General Care for the Freshwater Aquarium

Okay, so you have decided that you want to own an aquarium. It is a good idea to make out a wish list before purchasing any fish for the aquarium. Keeping an aquarium will require patience. Unfortunately, it is not realistic to go the pet store and just start picking out fish. Take a trip to the pet store in order to gather information and window shop to determine the types of fish you wish to keep in your aquarium. Carefully research these fish to ensure that they are compatible for water temperatures and P.H., as well as the food that they eat. Be careful not to put prey and predator together in the same tank. Keep in mind that freshwater fish are hardier than the marine variety, and will be less susceptible to water fluctuations.

One reason that freshwater fish are hardier than saltwater fish is the saltwater itself. Just like any living creature, a fish’s body requires water in order to function properly. Water is absorbed through a fish’s skin in the freshwater environment. Alternatively, a saltwater fish actually has to drink the salt water, because the body fluids are extracted through the skin by osmosis. The salt is then excreted in the form of highly concentrated urine. Freshwater fish are a good choice for an inexperienced aquarium owner because there is more wiggle room in the water specifications. Some freshwater fish have a variation of as much as ten degrees of acceptable water temperature. Conversely, most tropical fish will only allow about two degrees of variation in water temperature

It is not uncommon for the novice fish keeper to become easily discouraged. Water conditions are hard to regulate and unfortunately fish, even the freshwater variety, are not the hardiest of creatures. Sometimes they do not survive these fluctuations. It is important to be patient. An aquarium needs to run for a minimum of twenty four hours before adding any fish at all. You may want to allow the tank to run and filter with decorations and any plant life for a few days before introducing the fish. Be sure to clean the decorations and any substrate thoroughly before adding them to the aquarium. Live plants are highly recommended in new aquariums as they will help to generate the good bacteria necessary to reduce the amount of ammonia in the tank. It is a good idea to test the ammonia and nitrite levels before adding fish to the aquarium. Begin by adding only three to four small fish. A general rule is to wait another thirty days before adding additional fish, because that is the incubation period for most fish illnesses. In addition, test the nitrite and ammonia levels before adding these additional fish. The ammonia levels should return to zero. This also takes about a month.

There are a few basic tips that will keep fish healthy. Don’t over feed the fish. Any excess food will become debris in the tank, and then turns into ammonia, which is toxic to fish. Change the water in the aquarium regularly. Replace approximately one third of the water in the tank every two to three weeks. This will minimize the disruption to the fish in the aquarium, eliminating the need to remove the fish from the tank. Lastly, don’t forget to clean the filter. Follow the manufacturer’s instructions, as some filters need to be replaced more frequently than others

Marine Aquarium Care- Invertebrates Only

The care required for an invertebrate only tank is very similar to that of any other saltwater tank; however, the invertebrates are far less hardy than fish. It is recommended that you become skilled with a fish only tank before attempting an Invertebrate aquarium. Most Invertebrates require a specialized diet. Check with the supplier before purchasing and be sure that you are willing to make the commitment to have food delivered if necessary. There are two different types of invertebrates, tropical and cold water. Make sure that the type you are buy is compatible with its other tank mates.

A few examples of tropical invertebrates are tubeworms, red hermit crabs, cleaner shrimp and the sea apple. All of this marine life is compatible in terms of water conditions. They require a water temperature between seventy five and seventy nine degrees Fahrenheit, a P.H. between 8.2 and 8.4 and a salinity content of 1.020-1.024. As you can see, there is very little wiggle room associated with these measurements. It is extremely important to check the levels daily, or the results could be costly. These invertebrates are not compatible, however, with their food source needs. Check with the supplier for compatibility before combining tropical invertebrates.

Unlike their tropical counter parts, cold water invertebrates are usually not sold in stores. They have to be collected from tide pools. It is important to make sure that these species are not on the endangered species list before removing them from their home. It is equally important to do research in order to verify that you are able to properly feed them and care for their very specific needs. Sea Anemones, prawns, shrimp, and starfishes are a few varieties that have been successfully maintained in an aquarium. They require a water temperature between fifty four and fifty nine degrees Fahrenheit, a P.H. between 8-8.4 and a salinity content of 1.024-1.025. Luckily they do eat the same food. They feed off of a diet of small pieces of raw fish, shrimp, squid and mussels.

When keeping cold water invertebrates such as the species mention above, it is a good idea to keep a separate tank full of shrimp, mussels, and scallops to be used as a food source, if you wish to use fresh rather than frozen foods. Be careful when keeping shrimp, as all of the invertebrates listed above feed on shrimp, including shrimp themselves. It is unlikely, however that a healthy live shrimp will be eaten whole by another shrimp or starfish. Invertebrates should be fed more frequently in smaller amounts than fish. Try to feed only an amount that can be consumed in the first thirty to sixty seconds.

When setting up an invertebrate tank remember to include live rock, because some invertebrates feed on the parasites that grow on the live rock. A substrate should also be included in this type of aquarium. It will provide a place for the crabs and shrimp to dig and bury themselves. A light should be included as well, if you intend to keep anemones.

Coldwater Aquarium Set-up and Care

As the hobby of having an aquarium becomes more and more popular, it should be noted that the easiest aquarium to care for and set up is a coldwater tank. As the name suggests, coldwater tanks require no heating set up. This cuts costs when setting up your first tank. It also makes the aquarium much easier to maintain in the long run. Keep in mind that only certain coldwater fish can survive in a tank without heat. Most common are goldfish and guppies, but there are a multitude available and you will be able to have an array of fish living in your coldwater tank.

The supplies you will need to set up your aquarium may seem lengthy, but it is actually a much shorter and cheaper list than that of a heated freshwater tank or a saltwater tank. Obviously the first thing you need is a tank. It’s all about personal choice here as they come in many sizes and shapes. When you purchase the tank, a kit often comes with it and includes some of the other things you may need. Just to make sure, check that you have a filter and  an air pump. These are the most important pieces to the whole set up. If you are buying your tank as a kit, make sure it is specified to be a coldwater set-up. You will notice that no heater will be included.

After the purchase of your tank, you can now consider how you wish to decorate it. Many types of gravel and sand are available in a lot of colors. You can add accent plants as well to make it appear more natural. Many people add little figures or signs to personalize their aquariums. It’s all up to you in regards to décor. Be sure to buy a net, an algae scraper and conditioner for the water.

If you choose to have a tank with lighting, that is ok, just be aware of the problems it may cause. By adding light to the tank, you are also adding heat. Algae thrives on heat. Though a light won’t harm your tank, it may add to algae growth. This is not uncommon and is easily cleaned. Your fish will enjoy having the light, so it is probably best to buy a hood that includes a light. Try to keep the tank out of direct sunlight when you choose it’s position within your home. This will also add to algae growth.

Once you have your tank set up and the water is stabilized, you may add your fish. Be sure to only buy coldwater fish to add to this tank. If you are unsure of what types of fish are coldwater, ask for help at a pet store. They will offer you some extra tips on the types of fish you are purchasing as well. Once your fish are added, you will have a wonderful underwater scene to enjoy for years to come. It is important to clean and care for your tank on a routine basis. A complete cleaning of the tank should be done every 2 months, including a water change, scraping algae, rinsing the gravel of waste and changing filters.

You will find that as time passes, you will form a routing of caring for your coldwater aquarium. It is worth the effort to maintain the tank, as you will be rewarded with a wonderful addition to your home.

How to Care For Aquarium Fish

An aquarium is perhaps the easiest type of pet to have. There are some basic steps to caring for fish once the tank is established. There are things that should be done daily to care for fish and some things that need only be done weekly or bi-weekly. Daily maintenance of an aquarium is fairly minimal. Look at the fish every day to make sure they appear to be overall healthy and happy. This may seem silly, but the main cause of sickness in fish is stress. So, a happy fish is a healthy fish. Check to see that all lights and filters on the aquarium are plugged in and functioning correctly. Feed the fish daily. Only feed what can be consumed in the first two to five minutes. Any excess food will become debris in the tank and lead to illness or attribute to excess nitrite levels. You should check the water ph and temp weekly. Any necessary adjustment should be made promptly. Check with your local pet store when purchasing fish to find out what levels are appropriate. They vary amongst fish species.

Filter cleaning is extremely important. Filters collect waste excreted by the fish and left in the tank in the form of excessive fool. The filters will eventually fill with debris and be unable to do their job unless they are cleaned. In addition to eliminating waste, filter sometimes act as an aeration device cycling oxygen through the tank. If the filters are clogged, circulation slows. This limits the amount of oxygen in the tank. If left untreated, this could be deadly for your fish. Change the filter on the aquarium every two to three weeks depending on need. You will know when it needs to be cleaned because the water will become cloudy or smelly. Some filters need to be replaced, while other simply need to be cleaned with water.

The proper way to change water in a tank is to do it gradually. First unplug any lights and equipment before cleaning the aquarium. Change approximately one third of the water in the aquarium every one to two weeks. Water from the tap should be treated accordingly before adding to the tank and adjusted within two degrees of the aquarium. Again, check with your local retailer when purchasing fish. Some treatments allow the tap water to be ready in as little as an hour, while others need to sit overnight before being added to the tank.

Clean the sides of the tank with a scrubber to remove any built up algae. Be careful not to disturb or scare the fish. Move rocks and decorations to loosen any debris. Try to collect this debris when removing the water, either with a bucket or a vacuum type of siphon. Prune any dead leaves from aquatic plants. Clean the outside of the tank with a squeegee and clean tap water. Clean the cover and lid. Lastly, plug the aquarium back in, and enjoy the freshly cleaned tank.

Tips on Aquarium Care and Cleaning

The proper care and cleaning of your aquarium is the most important, yet most overlooked aspect of owning an aquarium. By avoiding the care and maintenance of a fish tank, not only will it lose the visual appeal, but your fish will be unhealthy and unhappy. By following a daily, weekly and monthly care program, you will maintain a beautiful, clean and healthy aquarium.

Daily Cleaning Routine

To maintain a clean aquarium, there are some daily tasks that must be done. First and foremost, it’s important to check the temperature of the tank and make sure it stays consistent. For tropical freshwater fish, the temperature should average at around 77 degrees. Too much heat in your aquarium will promote the growth of algae. Always check for sick or dead fish daily. If you have a sick fish, it should be removed from the tank immediately or it may harm the other inhabitants of the aquarium. Lastly, check that the pump and filter are functioning properly.

Weekly Cleaning Routine

Weekly maintenance is necessary to keep the tank healthy. On a weekly basis, any waste should be removed from the surface of the gravel at the bottom of the tank. Using a siphon tube will accomplish this. If water is removed during this process, be sure to replace it and keep the water in the tank at the same level. Add chemicals and chlorine weekly so the balance within the tank remains the same. At this time, it is best to test the water for the ammonia and nitrate levels. Don’t overlook testing the pH of the water as well. If you are raising live plants, tend to them each week. Trim them back if they are getting too big, and remove any dead or sick leaves. Re-anchor and new sprouts into your gravel. Also, check your tank for snails. You can remove snails by floating a piece of lettuce leaf in the tank. The snails will be attracted to the lettuce, and you can remove them using a net.

Monthly Cleaning Routine

Finally, some monthly steps will assure that your aquarium stays clean and healthy. A partial water change should be performed each month. Using a siphon hose, remove 20 to 25 percent of the water from the tank. Always make sure that your chemical balance is correct. High levels of chlorine and ammonia will cause death. Cleaning the filter should be a monthly task as well as changing the filter cartridge. Be sure not to clean the filter too thoroughly as it contains helpful bacteria that aids in stabilizing the chemical balance in the tank. During the monthly cleaning, scrape and remove all algae from the surface of the tank. If you find you are having a significant amount of algae, consider adding an algae eater to the tank. Should you already have one, be sure to keep an eye on the temperature of the tank and you may also want to limit the time in which a light is used. Any increased heat source will speed up the production of algae inside the aquarium. If your tank is located in direct sunlight and you are having an algae problem, it is best to relocate the tank.

By following a maintenance schedule, you will be sure to keep a clean, clear and healthy tank. Aquarium care is essential and must be performed regularly to ensure the long and happy life of your fish. Provide yourself with an aquarium to be proud of by keeping up with the care and cleaning.

Aquarium Care Guide- New Tanks

When starting a new aquarium it is important to understand the nitrogen cycle. Many new aquarium owners jump into the hobby of fish keeping too quickly. Before purchasing fish, the aquarium must be cycled. This could take anywhere from twenty four hours to four weeks. In an established aquarium there are certain bacteria that help the breakdown of ammonia to nitrates, but they are not present in a new tank because they are generated from existing fish. If there are no existing fish, then there are no good bacteria.

The basic principle of the nitrogen cycle is this. Fish eat food and generate waste. That waste along with excess food and plant debris become ammonia in the aquarium. Ammonia is toxic to fish and needs to be broken down. That’s why the nitrifying bacteria is important. This bacteria, turns the ammonia into nitrites which are more tolerable to fish than ammonia. Next, different nitrifying bacteria will turn the nitrites into nitrates, which are even less toxic to the fish and other aquarium life. The nitrates are collected and minimized by filters; however they will eventually accumulate in the tank. Regular water changes are required to remove the nitrates from the water.

It is important to set up and run an aquarium before any fish are introduced into the environment. Wash the tank and any substrate and decorations thoroughly with water. Don’t use any soap. Fill the tank with de-chlorinated water and attach filters and lighting. Allow the tank to cycle until the water is no longer cloudy and sufficient P.H and water temperatures have been established.

Now it is time to purchase the fish! Buy hardy fish such as danios, barb, gouramis, and live bearers. They should be able to withstand the high nitrite levels and ammonia in the new aquarium. Only introduce about four fish at a time. Float the fish in the bag in the aquarium for about fifteen minutes before adding them to the tank. This will help the fish become acclimated to the water temperature in their new home. When adding the fish, be careful not to allow the water from the bag into the aquarium. It may be contaminated, or will at the very least, throw off the temperature and P.H. Allow the fish about two hours to become acclimated before feeding.

Only feed an amount that can be consumed in the first two to five minutes. Overfeeding is a common problem in an aquarium. It is important not to overfeed, because excess food will become debris adding to the ammonia levels. This is especially important in new aquariums that lack nitrifying bacteria. Test the water P.H. every day within the first month. Watch the tank for cloudiness; if the aquarium becomes cloudy, it may be necessary to add a clarifier. Monitor the fish for signs of stress or illness. A healthy fish will be swimming regularly. Lethargic fish will usually hover near the surface of the aquarium. After about a week change approximately ten percent of the water and begin regular maintenance.

All about Care for an Acrylic Aquarium Kit

The practice of keeping aquariums came about in the late 1800′s. They were fairly crude. Usually these ancient aquariums only had one side that was made of glass, with the other three sides being made of metal or wood. Most aquariums consisted of fish that were native to the region of its owner simply because of availability. Also most old school fish tanks contained only fresh water fish. The reason being that salt water would corrode the metal frame that held the aquarium together.

Aquariums drastically changed in the 1960′s with the invention of silicone adhesive. Metal frames became obsolete and more people started to keep salt water fish and invertebrates. More recently glass tanks have become less frequently used due to the flexibility of acrylic. Literally flexibility! Acrylic aquariums are far more for forgiving than there glass counterparts. If a heavy object strikes a glass tank, it will almost certainly break. The flexibility of an acrylic tank will prevent this catastrophe from happening. In addition, acrylic offers more flexibility in design than glass. Acrylic aquariums have been made into everything from coffee tables to gum ball machines.

That being said, there is a short downfall to owning an acrylic aquarium. They do scratch more easily than glass. When cleaning your aquarium, be careful not to use paper towels, and harsh or abrasive chemicals, as they can scratch the acrylic surface of the aquarium. Always use a cleaner specifically labeled safe for acrylic. Use plastic or rubber scrubbers, rather than metal to clean the sides of an acrylic tank. Be careful not to accidentally pick up a piece of substrate or gravel while cleaning the inside of the tank. However, if you do happen to scratch an acrylic aquarium, all is not lost. The tank can be repaired, unlike glass. There are acrylic repair kits available at specialty pet stores, your local hardware store and of course online.

When purchasing an acrylic aquarium kit, there will be many different options to choose from, at many different price points. Aquarium kits can be purchased at places such as specialty aquatic pet stores, from huge retail chains, or again online. A fish lover can choose from small cylinder shaped tanks that can double as a coffee table lamp to wall huge wall sized aquariums. While, there are some basic things that will be included in most kits, such as, a filter, some substrate or coral and sometimes lighting, the kits themselves can vary greatly. It really doesn’t matter where you buy your starter kit, but keep in mind that it is extremely important to buy your fish from a reputable dealer. Don’t buy fish that are hovering near the surface, or that are located in a tank with other dead fish. Fish diseases are extremely communicable. Be weary of a fish dealer that refuses to catch a specific fish out of the tank for you. After all this is going to be your fish and you have a right to choose.

Caring for your Freshwater Aquarium

The most important factor of owning an aquarium is the proper cleaning of the tank. Many new owners are unsure of how to go about this. This information will help new freshwater aquarium owners keep a clean and healthy tank. These first two questions are the key to maintaining your aquarium allowing you to enjoy this beautiful addition to your home.

When should I clean my tank? You should clean your tank once every two months unless you can really tell it needs cleaned before then. Why should I clean my tank once every two months? Because your tank will start building up algae on the inside and your gravel will retain waste that could make your fish ill in the future.

The following steps are easy and quick and will provide your fish with a clean and happy aquarium.

Step 1 (prepare for cleaning)

You have to prepare for the steps to follow before removing your fish from your freshwater aquarium. There are some supplies you will need to clean the tank, so it’s best to have them handy before starting. You will need some kind of container that your fish can be placed in until it’s time for them to be put back in the tank. It doesn’t have to be a large container, but make sure your fish do have enough room to swim freely. This container is dependant on how many fish are living in the tank. You will also need a fish net, a towel or paper towels to wipe up any spills that may occur, a water pitcher or a bucket for refilling the tank, food drainer, a clean sponge, and a clean rag. After you have these things gathered, you’re now ready to begin cleaning your freshwater aquarium.

Step 2 (Removing your fish)

This may be the most important step in the cleaning process. It is time to remove the fish from the tank. The first thing to do is make sure that the container in which the fish are being placed has water that is about the same temperature at the tank, other wise your fish will go into shock. When the container of water is ready, use the net to catch each fish one-by-one and place them in the container. Once all the fish are collected, be sure to place the container in a safe place where it will not be spilled. It is common for fish to become stressed when they are moved, so the water temperature and reducing as much unneeded activity is very important.

Step 3 (Removing the fish tanks old water)

When all the fish are out of the tank, it is time to start emptying the water from the aquarium. Using the pitcher or small bucket, begin to remove the water. The water from the tank may be disposed in a sink or toilet. This can be a messy task, so be sure to clean up all spills to prevent any possible accidents. It is not necessary to remove all the water from the tank. Most freshwater aquarium owners remove approximately 3/4 of the water. The remaining original water will help acclimate the new water you will add later.

Step 4 (Removing and cleaning your tanks gravel)

Most of the waste that gathers in a tank settles into the gravel at the bottom. It is very important to clean the gravel when you clean your tank. At this time you will remove the gravel. You can use the fish net, a small scoop or even a dustpan to do this. Place the gravel in a container. Once you have removed all the gravel, transfer it into a strainer of some sort and run it under hot water. Be sure to mix it up while you are rinsing so that all the sediment and waste is removed. Once the gravel has been cleaned, place it aside. You will not be putting it back in the tank at this time.

Step 5 (Cleaning the tank)

Now it’s time to clean the inside of the tank. This can be a tedious chore if there is a lot of build-up on the glass. Some freshwater aquariums have algae growth on the glass. The warmer the water is inside and the more the aquarium is exposed to natural sunlight, the more algae growth you will have. This can be cleaned off by using a scratch pad. Try to use the least abrasive pad you can to avoid scratching the class. Cleaning with hot water will aid in the removal of algae. Make sure to never use any type of cleaner or detergent when cleaning the tank. This will be fatal to the fish. After removing the algae, finish by wiping down the rest of the tank with a towel or soft rag. You may have to repeat this a few times. Try to rinse the rag or towel frequently to remove all the waste. If you have decorative pieces in the tank, be sure to wash them as well using hot water. After completing these steps, your tank should be clean of waste and build-ups.

Step 6 (Putting it all back together)

Now it’s time to replace everything. Start by replacing the gravel into the tank, followed by refilling the water. Take notice of the temperature once again. Try to add water that is of the same temperature as the original water in the tank. Add your finishing touches with decorative pieces, then carefully move the fish back in. It may take a little while for the fish to adjust to the new water, but after having followed all these steps, you can be sure that your tank is clean and healthy.

You won’t have to completely clean your tank for another 2 months. Always remember to change the filters if they are dirty. As an added tip, if you remove 20% of the water every month and replace it with clean water, this will cut down on the complete cleaning of the tank in the future. To maintain a healthy tank, it is important to clean it properly and keep up with the aquarium care. By doing this, you will ensure a long life for your fish and an enjoyable experience for observers.

Caring for Bubble Coral in an Aquarium

As more and more people set up saltwater aquariums, more are also adding coral to the décor. As with any living thing, it is best to understand the creature and how to care for it properly before bringing it home. Coral is no different as it is a live animal that you will be adding to your tank. The care and maintenance of coral should be well understood before making the final decision to add this beautiful animal to your aquarium.
The most common species of coral that are used in aquariums are called bubble coral. Due to the fact that they are so common, we will use this species as a guideline. Within the bubble coral family, there are three subspecies. They are simple bubble coral, pearl bubble coral and grape bubble coral. They are all cared for in the same way, so they will be referred to as bubble coral throughout the rest of the article.

One of the most important things to know about your coral is how to space them when you add them to the tank. Bubble coral have long tentacles which are armed with stinging cells. Mostly, they remain retracted until nightfall, when they are extended to aid in feeding habits. These tentacles will sting neighboring coral if they are close enough. Be aware of this as you position the coral in your tank and try to keep coral pieces at least 6 inches away from others.

As your consider the placement. Also take into consideration the available lighting where they are placed. If you have additional light sources aside from the tube in the hood, bubble coral should do well anywhere in the tank. If you are using the included florescent tubes for lighting, it may be better to place the coral closer to the surface. This species of coral prefers low movement of the water. Be sure not to place it in any direct current. Doing so will cause the coral’s vesicles to remain closed. This will eventually result in death.

When you have the coral situated in the aquarium, you must remember it is a living animal and must eat just as your fish do. For bubble coral, feed it shrimp or small pieces of clam one to two times a week. Place the food morsels on the polyp of the coral. Any food that is trapped by the tentacles or among vesicles, will be eaten almost immediately. It is important not to overfeed the coral or your fish. Algae is a pest that will cause damage or even death of the coral. Keep the algae as controlled as possible by scheduled and routine cleaning of your aquarium. Bubble coral may also get flat worms. These worms are easily spotted and usually appear as circular spots on the coral’s vesicles. They are not a cause for alarm and usually do little damage if any. However, if you notice a significant amount or a large population of these worms, you will have to take action as they could cause death.

Coral is a wonderful addition to any aquarium. Many people are uninformed as to how to care for this animal. It is advised that you learn all you can about the animal, how it functions and lives before adding it to the aquarium. Once you have the knowledge and can properly care for it, coral will help to create a studding underwater paradise.

Aquarium Care for the Freshwater Guppy

Guppies are perhaps the most popular type of freshwater fish to keep in an aquarium. Luckily, they are fairly easy to keep as well. Guppies are hardy fish that can adjust easily to minor fluctuations in water quality. However, don’t allow these fluctuations to become common practice, as they do cause some stress to the fish. The water temperature in an aquarium for guppies should be kept between seventy two and eighty two degrees. The P.H. level should be kept between 7.0 and 8.2. As you can see these specifications are much more forgiving than those for certain tropical or marine fish. Guppies mature quickly and usually only grow to be about one and a half to two inches long. There small bodies and feathery fan like tails add a lot of interest to the tank. They are just fun to watch.

As with any type of aquarium, there are three basic components to caring for the fish. Diet is very important. Guppies should be fed very small amounts as often as three times a day. Guppies will eat just about anything, but their main diet should consist of frozen or flake foods. This should be especially regarded when there are baby guppies in the tank, because guppies will eat their young. The next most important feature to caring for any fish is appropriate water regulation. The specific temperatures are listed above, but it is also important to make frequent water changes. Usually every one to two weeks, depending on need. If the water starts to smell or become cloudy, this is a good indication that it is time to change the water. If water changes are made gradually, meaning change approximately one third of the tank at a time, then there is little disruption made to the fish.

Last on the list for keeping fish healthy, is to keep them happy. Try to recreate their natural environment. It is recommended to keep a variety of plants in the aquarium for guppies to seek refuge. There should be about one to two inches of substrate in the bottom of the tank. Colored rock or dead crushed coral make a nice addition to the aquarium, and may help to make the fish feel more at home.

A few varieties of guppies are the Fantail, Flagtail, Spadetail, Deltatail and the Roundtail. The names of all of these different types of guppies focus on the tails because they are so remarkable and unique. The tail itself is usually about one third of the size of the whole fish. It is possible to mix guppies with other varieties of fish. However be careful when mixing because, guppies are targeted as easy prey due to those fancy tails. Guppies breed very quickly, usually about every three to four weeks. They will interbreed amongst themselves, so the aquarium could very quickly become filled with many different varieties of color. It is very feasible to have an attractive aquarium without having any other fish at all. If you don’t want the species to interbreed, simply keep them in separate tanks.
