Fantail Guppy: Why Their Care Requirements Are Unique

The Fantail guppy is a member of the family Poeciliidae. The fantail guppy is a popular aquarium fish due to its vibrant colors and tail shape. The fish is small, typically only growing to 2-3 inches in length. The male fantail guppy is usually more brightly colored than the female and also has a bigger and more extravagant tail.

Fantail guppies are known to be peaceful community fish. A Fantail Guppy Tank Community should have at least 5-6 different fish species that are all relatively the same size. They do well with other small, peaceful fish such as neon tetras, mollies and platies. Larger tank mates should be avoided as they may see the guppy as food. Like all aquarium fish, fantail guppies need a properly balanced diet to stay healthy.

A diet for a fantail guppy should include live food, frozen food and flake food. A fantail guppy's perfect aquarium habitat has a natural gravel substrate with live plants. This type of varied habitat will be fascinating and entertaining for the Fantail guppies, while live freshwater aquarium plants provide further protection for Fantail guppies that are born in the tank.

One of the things that makes fantail guppies so popular is that they are easy to care for. They are very hardy fish and can tolerate a wide range of water conditions. To learn more about fantail guppy care, read on.

Fantail Guppy Care

If you're thinking of getting a guppy fish, the fantail guppy is a popular choice. They're striking fish with beautiful tails, and they're relatively easy to care for. However, there are some things you need to know about caring for a fantail guppy that is unique to this species.

Fantail guppies are relatively easy to care for, but they do have some specific requirements. For example, they need a lot of plants in their tank. This is because they like to hide, and plants provide them with places to do that. They also need a lot of food, since they're constantly grazing.

One thing you need to be aware of when caring for fantail guppies is that they're very sensitive to changes in water quality. This means that you need to be very careful about water changes and make sure the new water is of the same quality as the old water.

Another thing to keep in mind is that fantail guppies are livebearers. This means that they give birth to live young, and you may end up with more fish than you started with! Overall, fantail guppies are relatively easy to care for as long as you keep their specific needs in mind. With a little bit of care, they make wonderful additions to any aquarium.

Fantail Guppy Size

On average, fully grown Fantail guppies are about two inches long. Female guppies reach twice the size of male guppies when they mature. Their average size is 0.6–2.4 inches. Juvenile guppies are usually about half the size of an adult.

Fantail Guppy Lifespan

Male and female Fantail guppies can live for two years in the wild and up to three years in captivity. Guppies can live longer in captivity than in the wild because guppies in the wild are exposed to more predators.

Fantail Guppy Appearance

The fantail guppy males' caudal fins are roughly as long as the fish's body, and they're enormous and distinctive! The breed's typical characteristic is a long, triangle-shaped tail with straight sides. This breed's distinctive feature is its large, triangular dorsal fin.

These guppies come in a variety of colors, including blue, yellow, red and black. In fact the Fantail guppy is a species of fish that come in all sorts of colors. Fish owners prefer them because they are easy maintenance and hardy. Fantail guppies are also known to have patterns on their bodies.

The most common pattern is the tiger pattern, which consists of black stripes on a light background. Fantail Guppy Yellow and Red are the colors that are most popular in the fish world. Red Fantail guppies are high in demand.

Fantail Guppy Food & Diet

A well-rounded diet is essential for fantail guppies to stay healthy. For the healthiest guppy diet, feed them a combination of live food and fish flakes that contain both veggies and protein. Fantail guppies adore live foods such as microworms and baby brine shrimp.

Feed your Fantail guppies once in the morning and once at night, an hour after the aquarium light comes on and an hour before it goes out. If you don't want your guppies to eat food that's been sitting out, only give them as much as they can finish within the hour. Gradually reduce the amount you're giving them at each meal until there's zero waste.

Fantail Guppy Behavior

Fantail Guppies are gentle fish that feel more comfortable and secure when swimming in schools with other guppies. They are rapid, active swimmers who usually spend their time investigating and chasing each other. Male guppies predominantly try to attract females by displaying their impressive swimming speed and patterns.

Guppies are typically peaceful, but they can become aggressive bullies if other fish challenge them during feeding or if the tank is too small. Although guppies will swim in all areas of the tank, they generally prefer to stay near the top where it is close to the surface of the water. When guppies feel playful or threatened, they enjoy swimming in the open but also find safety in hiding behind plants and in caves. Guppies prefer to sleep in the dark and are most active during daylight hours. They also tend to eat more during the day.

Fantail Guppy Tank Mates

Although guppies play nice with other fish, their small size makes them a potential meal for bigger fish and a target for aggressive ones. So Fantail guppies should be kept with other small fish that won't bully or harm them. Fantail Guppy Swims Along Surface, so pick tank companions that stay near the bottom and in the middle of the aquarium to keep them from getting in each other's way.

Suitable tank mates for guppies include:

  • Cory catfish
  • Rummy nose tetras
  • Sparkling Gouramis
  • Mollies
  • Kuhli loaches
  • Cardinal tetras
  • Harlequin Rasboras
  • Dwarf chain loaches
  • Zebra danios

Non-fish tank mates for guppies include:

  • Shrimp
  • Nerite snails

Fantail Guppy Tank Setup

Fantail guppies are found in fresh and brackish water habitats in the wild, so they will do best in an aquarium with similar water conditions. Here are a few things you need to consider while setting up a tank for your Fantail guppies:

Tank Size and Population

Fantail guppies are social creatures who do best when living in a group, or at school. The number of fish in your fantail guppy school will depend on the size restriction of your tank. A good rule of thumb is one gallon of water for each fantail guppy.

A 10-gallon fish tank should never house more than 10 fantail guppies. Fantails need a lot of space to move around, so when picking a tank size, always go bigger. You will need a larger fish tank if you plan on adding fish that are compatible with fantail guppies. Some examples of these types of fish include neon tetra, glass fish and cory catfish.

Water Conditions 

A pH of 7.0 is ideal for fantail guppies, although a slight fluctuation in water pH levels of 6.0 to 8.0 is okay for the aquarium; an aquarium pH water kit will help you keep the water pH around a neutral level. Fantails need a water temperature of 70 to 78 degrees Fahrenheit, and guppies are especially susceptible to harm from sudden changes in water temperature. You can use an aquarium light or heater to keep the water at a steadier temperature.

Good water quality is vital to guppy health and preventing disease. For a healthy and clear aquarium, the International Guppy Society suggests changing 30%-40% of the water every week. In addition, using an air pump and filtration system will help maintain cleanliness.


Make sure to verify that the filter accompanying the aquarium is able to clean sufficiently for both the tank size and number of fishes. Please be sure to follow the instructions on how to properly install your filter. Your tank's filter is key in maintaining oxygen levels, so be sure to check it frequently for dirt and discoloration.

Fantail Guppy Breeding

Guppies are easy to breed--many will do so even if you don't encourage them to! Guppies are ovoviviparous, meaning that the females carry their eggs inside their bodies until they hatch. Selective breeding of guppies has led to the development of many different colors and patterns.

If you want to breed guppies, follow these steps:

  • For less stress on the female guppies, choose one male and up to three females. The males will then attend equally to all of the females.
  • For 10-gallon fish tanks, install a filter, low-floating plants, and caves. This will provide optimal conditions for breeding guppies. Make sure to set the tank temperature to 79 degrees Fahrenheit.
  • After you put the male and female guppies in the breeding tank, wait for them to mate. The male will breed with one or more females several times so that eggs are definitely fertilized.
  • If you see a dark mark (Gravid Spot) on a female guppy's stomach, it means that she is pregnant. To determine how many fish are pregnant, check the females. Afterwards, remove the male and any non-pregnant female fish and return them to the home tank.
  • Allow the pregnant females to gestate for approximately one month. Feed them 3-5 times daily with small, highly nutritious meals.
  • Keep a close eye on female guppies during the birthing process, as they will hide and shiver just before giving birth. Once the fry have been born, return the mother to her home tank to prevent her from eating them.
  • Replace 40% of the tank's water every three days with new water, and feed the fry powdered fish food flakes and brine shrimp. Do this until the fry are six weeks old or older, or big enough to join a regular-sized tank.

Fantail Guppy Fry

Fantail Guppy fry (baby guppies) are born fully-formed and free-swimming, and can fend for themselves almost immediately. However, they are extremely vulnerable to predators at this stage of their lives. For this reason, it's best to keep them in a separate fry tank until they're big enough to join the adults.

To ensure that your fry thrive, you'll need to provide them with plenty of hiding places. Fine-leaved plants like java moss are ideal, as the fry can tuck themselves away in the dense foliage. You'll also need to provide them with plenty of live food, such as brine shrimp or daphnia.

As they grow, you can gradually start to introduce them to other foods, such as flake food or pellets. Be sure to remove any excess food, as it can quickly pollute the water.

Once they reach adulthood, fantail guppies are relatively easy to care for. They're adaptable creatures that can thrive in a range of different tank conditions. With proper care, your fry will grow into healthy adults in no time!

Fantail Guppy Diseases 

Guppies kept as pets are vulnerable to several diseases. Guppy disease is a catch-all term used to describe a range of different infections that can affect these fish.

Here are some of the common symptoms of guppy disease:

  • White spots on the skin
  • Frayed fins
  • Loss of appetite
  • Lethargy
  • Unusual behavior
  • Weight loss

If you notice any of these symptoms in your fish, it's important to take action immediately. The sooner you treat the infection, the better the chances are of your fish making a full recovery.

There are a number of different treatments available for guppy disease. Some common methods include using anti-fungal medications, changing the water conditions, and increasing the temperature of the tank.

If left untreated, guppy disease can be fatal. However, it can be easily prevented by maintaining good water quality and ensuring that your fish have a nutritious diet. Here are some of the most common diseases that can affect fantail guppies:

Protozoan Disease

Because Protozoan disease is so common in guppies, it has earned the nickname "guppy disease." The disease is most often caused by a single-celled protozoan creature called Tetrahymena sp., and it typically thrives where water quality is poor or the temperature isn't warm enough.

Symptoms of protozoan disease include:

  • Loss of appetite.
  • Problems breathing.
  • Excess slime production.

By regulating water conditions and temperature between 74-82 degrees Fahrenheit, the disease can be effectively treated.


Ich is a common fish disease that affects both freshwater and saltwater fish, including guppies. A guppy with ich will have white spots on its body and might often scratch against Tank surfaces.

Ich is caused by a parasite called Ichthyophthirius multifiliis. To treat it, quarantine the affected fish and increase water temperature by two degrees. This will speed up the parasite’s life cycle, causing it to die off faster. In order to treat Ich, you can dissolve one tablespoon of salt in every five gallons of the fish’s tank water.

Fin Rot and Tail Rot 

Inconsistent water parameters, stress, and overcrowding are the primary causes of fin rot and tail rot in guppies with lengthy fins.

The symptoms of fin rot are a discoloration or milky coloration, as well as ragged, frayed, and shortening fins. The best way to treat fin rot and tail rot is by doing a full water change and using antibiotics recommended by your veterinarian.

Fantail Guppies are also susceptible to a number of other diseases, including:

  • White spot disease
  • Velvet disease
  • Columnaris disease
  • Popeye

If you think that your fish might be suffering from guppy disease, it's important to consult a veterinarian who specializes in treating fish. They will be able to diagnose the problem and recommend the best course of treatment.

Preventing Fantail Guppy Disease 

The best way to prevent guppy disease is to maintain good water quality and to ensure that your fish have a nutritious diet. Here are some tips for preventing guppy disease:

  • Test your water regularly and make sure that the ammonia, nitrite, and nitrate levels are all within the safe range.
  • Keep your tank clean and free of debris.
  • Avoid overfeeding your fish.
  • Don't overcrowd your tank.
  • Quarantine new fish before adding them to your main tank.
  • Be sure to treat your fish with a dewormer on a regular basis.
  • Keep an eye out for early signs of disease and take action immediately if you notice anything abnormal.

By following these tips, you can help to prevent guppy disease and keep your fish healthy and happy.
