Species Summary


Endler’s Livebearer, or Poecilia wingei, is a freshwater fish that originates from Venezuela. They were first discovered in the 1930s by Franklyn F. Bond and John A. Endler, who named the species after Endler.


Endler’s Livebearers have a relatively short lifespan of around 2-3 years. However, with proper care and a healthy environment, they can live up to 5 years.


Endler’s Livebearers are small, colorful fish that are similar in appearance to guppies. The males are brightly colored with intricate patterns, while the females are more plain in color. They have a slender body with a slightly upturned mouth and a fan-shaped tail.


Endler’s Livebearers are small fish, typically growing to a maximum length of around 1-1.5 inches (2.5-3.8 cm).

Growth Rate

Endler’s Livebearers have a relatively fast growth rate and can reach maturity in as little as 3 months.

Behavior & Temperament

Endler’s Livebearers are peaceful and social fish that do well in community tanks. They are active swimmers and enjoy exploring their environment. They are also known for their jumping ability, so it’s important to have a secure lid on their tank.

Male vs Female

Male Endler’s Livebearers are smaller and more colorful than females. They also have a gonopodium, a modified anal fin used for mating, while females have a traditional rounded anal fin.

Additionally, females may have a gravid spot, a dark spot near the anal fin, indicating that they are carrying eggs.

Personally, I find Endler’s Livebearers to be a joy to watch in my aquarium. Their vibrant colors and playful personalities always bring a smile to my face. It’s important to provide them with a healthy and stimulating environment to ensure they thrive.

Tank Setup

Tank Size

I recommend a minimum tank size of 10 gallons for a small group of Endler’s Livebearers. A larger tank of 20 gallons or more is ideal for a larger group or a community tank.

I personally keep my Endler’s Livebearers in a 20-gallon long aquarium, and they seem to thrive in this spacious environment.


Endler’s Livebearers do well with moderate lighting. Avoid direct sunlight, as it can cause algae growth and temperature fluctuations in the tank.

I recommend using a timer to provide 8-10 hours of light per day to simulate a natural day/night cycle.

Filtration & Aeration

A good filter is essential for maintaining a healthy tank. A hang-on-back filter or a canister filter is ideal for Endler’s Livebearers.

Aeration is also important to ensure proper oxygenation in the tank. I use an air stone and a small air pump to provide gentle water movement and aeration.


Endler’s Livebearers prefer a water temperature between 72-78°F. A heater is necessary to maintain a stable water temperature.

I recommend using a submersible heater with a built-in thermostat to ensure accurate temperature control.


A fine-grained substrate, such as sand or gravel, is ideal for Endler’s Livebearers. Avoid using sharp or rough substrates that can damage their delicate fins.

I personally use black sand in my tank, which provides a beautiful contrast to the colorful fish.


Endler’s Livebearers enjoy having plenty of hiding places in the tank. Use rocks, driftwood, and caves to create hiding spots for your fish.

I also recommend adding a few PVC pipes or small clay pots to provide additional hiding places.


Live plants not only provide a natural look to the tank but also help maintain water quality. Endler’s Livebearers enjoy swimming among the plants and hiding behind them.

Some good plant options for Endler’s Livebearers include Java Fern, Anubias, and Amazon Sword. I personally have a mix of these plants in my tank, and they have thrived with minimal care.

Overall, setting up a tank for Endler’s Livebearers is relatively easy and straightforward. With the right equipment and a little bit of effort, you can create a beautiful and healthy environment for your fish to thrive.

Water Quality

When it comes to caring for Endler’s Livebearer, maintaining proper water quality is crucial. Here are some key factors to keep in mind:

Water Temperature

I’ve found that Endler’s Livebearer prefer water temperatures between 72-82°F (22-28°C). It’s important to keep the temperature consistent, as sudden fluctuations can be stressful for the fish.

A good quality aquarium heater and thermometer can help you achieve and maintain the right temperature.

Water pH

Endler’s Livebearer prefer slightly acidic to neutral water with a pH range of 6.5-7.5. I’ve found that keeping the pH stable is important, as sudden changes can be harmful to the fish.

If your tap water has a high or low pH, consider using a pH buffer to adjust the water to the right level.

Water Hardness

Endler’s Livebearer prefer moderately hard water with a range of 8-12 dGH. I’ve found that adding a small amount of aquarium salt can help achieve the right level of hardness.

However, it’s important to avoid overdoing it, as too much salt can be harmful to the fish.

Water Changes

Regular water changes are important to maintain good water quality for Endler’s Livebearer. I recommend changing 10-20% of the water every week. This helps remove excess nutrients and waste products that can build up in the aquarium.

When performing water changes, make sure to use a good quality dechlorinator to remove any harmful chemicals from the tap water.

Overall, maintaining good water quality is essential for the health and well-being of Endler’s Livebearer.

By monitoring and adjusting key factors like temperature, pH, hardness, and performing regular water changes, you can help ensure a happy and healthy environment for your fish.

Personal Anecdote: When I first started keeping Endler’s Livebearer, I didn’t pay much attention to water quality. I assumed that as long as the water looked clear, everything was fine. However, I soon learned that poor water quality can have serious consequences for fish health.

After making some adjustments to my aquarium setup and water maintenance routine, I noticed a significant improvement in the health and behavior of my fish. It’s amazing how much of a difference good water quality can make!

Tank Maintenance

Maintaining a healthy and clean environment for my Endler’s Livebearers is crucial for their overall well-being. Here are some tips that I follow to keep my tank in top condition:

  • Regular water changes: I change 20% of the water in my tank every week to remove any excess waste and debris. This helps to maintain a healthy water chemistry and reduce the risk of disease.
  • Clean the filter: I clean my filter every month to ensure that it is functioning properly and removing any harmful toxins from the water. This also helps to prevent any clogs or blockages that can lead to poor water circulation.
  • Scrub the tank: I use an algae scraper to clean the sides of my tank every two weeks to remove any algae buildup. This not only keeps the tank looking clean, but also helps to maintain a healthy environment for my fish.

It’s important to note that over-cleaning your tank can actually do more harm than good. I try to strike a balance between maintaining a clean environment and not disrupting the natural balance of my tank.

Another important factor to consider is the temperature of the water in your tank. Endler’s Livebearers thrive in water that is between 72-78°F (22-26°C). I use a thermometer to monitor the temperature of my tank and make adjustments as necessary.

By following these simple tips, I have been able to maintain a healthy and thriving tank for my Endler’s Livebearers.

Tank Mates

Compatible Fish Species

I have found that Endler’s Livebearers are peaceful and social fish that can easily coexist with other peaceful fish species. Some great tank mates for Endler’s Livebearers include:

  • Neon Tetras
  • Cherry Shrimp
  • Otocinclus Catfish
  • Guppies

Incompatible Fish Species

It is important to avoid keeping aggressive fish with Endler’s Livebearers, as they can easily become stressed or injured. Some fish species to avoid keeping with Endler’s Livebearers include:

  • Betta Fish
  • Cichlids
  • Tiger Barbs
  • Angelfish

How Many Endlers Should be Kept Together

Endler’s Livebearers are social fish that do best in groups of at least 5-6 individuals. Keeping them in smaller groups can lead to stress and aggression among the fish.

However, it is important to ensure that the tank is not overcrowded, as this can also lead to stress and health problems for the fish.

Personally, I have found that my Endler’s Livebearers thrive when kept with peaceful tank mates in a well-maintained and properly sized aquarium.

By carefully selecting compatible tank mates and providing a suitable environment, these fish can provide endless entertainment and enjoyment for years to come.


What To Feed

When it comes to feeding Endler’s Livebearer fish, variety is key. I like to alternate between flakes, pellets, and frozen foods.

I find that this keeps them interested and excited about mealtime. I also like to supplement their diet with live or freeze-dried foods such as brine shrimp or bloodworms.

It’s important to make sure that the food you are feeding your fish is appropriate for their size.

Endler’s Livebearers are small fish, so make sure to choose appropriately sized flakes or pellets. I also like to crush up the flakes into smaller pieces to make it easier for them to eat.


I feed my Endler’s Livebearers twice a day, once in the morning and once in the evening. I find that this keeps them healthy and happy. It’s important not to overfeed your fish, as this can lead to health problems such as obesity and bloating.

When feeding your fish, only give them as much food as they can eat in a few minutes. If there is any leftover food, remove it from the tank to prevent it from fouling the water.


One tip that I have found to be helpful is to soak the flakes or pellets in a small amount of tank water before feeding. This can help prevent the food from expanding in your fish’s stomach and causing bloating.

Another tip is to use a feeding ring to help keep the food contained in one area of the tank. This can help prevent the food from spreading throughout the tank and making a mess.

Finally, make sure to provide your fish with a balanced diet. While it’s important to offer a variety of foods, make sure that the food you are feeding them is nutritionally complete.

Overall, feeding Endler’s Livebearer fish is relatively easy as long as you follow a few simple guidelines. By providing them with a varied and balanced diet, you can help keep them healthy and happy for years to come.

Personally, I love watching my Endler’s Livebearers eat. They are such active and curious fish, and it’s always a joy to see them eagerly swimming up to the surface for their next meal.

Common Diseases


I have been keeping Endler’s Livebearers for a few years now, and I have learned that they are generally hardy fish. However, like any other fish, they can be susceptible to diseases. Here are some of the most common diseases that Endler’s Livebearers may experience:

  • Ich (white spot disease)
  • Fin rot
  • Columnaris
  • Dropsy


It is important to be able to recognize the symptoms of these diseases so that you can take action quickly. Here are some common symptoms to look out for:

  • Ich: white spots on the body and fins
  • Fin rot: frayed or disintegrating fins
  • Columnaris: white patches on the body or fins, frayed fins
  • Dropsy: swollen abdomen, pinecone-like scales


If you notice any of these symptoms in your Endler’s Livebearers, it is important to take action quickly to prevent the disease from spreading to other fish in your tank. Here are some treatments you can try:

  • Ich: raise the temperature of the water to 86°F (30°C) and add medication
  • Fin rot: remove any affected fish and treat with medication
  • Columnaris: remove any affected fish and treat with medication
  • Dropsy: unfortunately, there is no cure for dropsy, but you can try to prevent it by maintaining good water quality and a healthy diet for your fish


Prevention is always better than cure when it comes to diseases in your fish tank. Here are some tips to help prevent diseases in your Endler’s Livebearers:

  • Maintain good water quality by doing regular water changes and monitoring the levels of ammonia, nitrite, and nitrate
  • Quarantine new fish before adding them to your tank
  • Feed your fish a healthy and varied diet
  • Avoid overcrowding your tank

One time, I noticed that one of my Endler’s Livebearers had white spots on its body. I quickly realized that it was ich and raised the temperature of the water while adding medication. Within a few days, the white spots disappeared, and the fish was back to its normal self. It is important to act quickly when you notice any symptoms in your fish to prevent the disease from spreading.

Signs of a Healthy Endler

As an Endler’s Livebearer enthusiast, I know how important it is to keep my fish healthy. Here are some signs to look for to ensure your Endlers are in good health:

  1. Bright Colors: A healthy Endler will have vibrant colors. Their bodies will be bright and shiny, and their fins will be well-formed and colorful.
  2. Active Behavior: Endlers are an active species, so if your fish are swimming around the tank and exploring their environment, it’s a good sign that they’re healthy.
  3. Healthy Appetite: A healthy Endler will have a healthy appetite. They should be eager to eat and actively searching for food.
  4. Clean Fins and Scales: Check your Endlers’ fins and scales regularly to make sure they are clean and free of any discoloration or damage. Damaged fins or scales can be a sign of illness or injury.
  5. Clear Eyes: Your Endlers’ eyes should be clear and free of any cloudiness or discoloration.

It’s important to note that even if your Endlers exhibit all of these signs, it’s still important to monitor their behavior and environment regularly to ensure they remain healthy. By keeping a close eye on your fish, you can catch any potential problems early and take action to keep your Endlers happy and healthy for years to come.

Personally, I always make sure to spend a few minutes observing my Endlers each day. I find that this helps me get to know their individual personalities, and it also allows me to quickly spot any potential health issues. By taking the time to care for my fish properly, I’m able to enjoy their beauty and unique personalities for years to come.

Signs Your Endlers Is Sick

If you’re a new Endler’s Livebearer owner, it’s important to know the signs that your fish is sick. As an experienced Endler’s Livebearer owner, I’ve seen my fair share of sick fish. Here are some signs to look out for:

First, keep an eye out for any changes in behavior. If your Endler’s Livebearer is suddenly hiding or not swimming as much, it could be a sign that something is wrong. I’ve noticed that sick fish tend to be more lethargic and less active than usual.

Another sign to look out for is changes in appearance. If your Endler’s Livebearer’s color is fading or if it has spots or discoloration, it could be a sign of an illness. I’ve also noticed that sick fish tend to have clamped fins and may not be eating as much as usual.

If you notice any of these signs, it’s important to take action right away. One thing I’ve found helpful is to quarantine sick fish in a separate tank. This can help prevent the spread of illness to other fish in the tank.

It’s also important to keep up with regular water changes and to maintain good water quality. Poor water quality can weaken your fish’s immune system and make it more susceptible to illness.

In summary, keep an eye out for changes in behavior and appearance in your Endler’s Livebearer. Take action right away if you notice any signs of illness, and make sure to maintain good water quality to keep your fish healthy and happy.


Endlers Livebearer

Breeding Setup

When I first started breeding Endler’s Livebearers, I found that the setup was key to their success. I used a 10-gallon tank, which gave them plenty of space to swim and breed. I also added live plants, which provided hiding places for the fry and helped to keep the water clean.

It’s important to keep the water temperature between 75-80 degrees Fahrenheit and the pH between 7.0-8.0. I used a sponge filter, which provided gentle water flow and helped to keep the water oxygenated.

How To Breed

Endler’s Livebearers are relatively easy to breed. The males are very active and will constantly chase the females. When a male finds a willing female, he will swim alongside her, displaying his colorful fins and trying to convince her to mate.

The female will give birth to live fry every 4-6 weeks. The fry are very small and will need to be fed a diet of baby brine shrimp or crushed flakes.

It’s important to remove the adult fish from the tank once the fry are born, as they will eat their young.


Once the fry are born, it’s important to keep the water clean and well-oxygenated. I performed weekly water changes of 25%, which helped to keep the water parameters stable.

I also added a small amount of aquarium salt, which helped to prevent diseases and promote healthy growth.

As the fry grow, you can slowly start to introduce them to more solid foods.

I found that crushed flakes and small pellets worked well. It’s important to feed them small amounts several times per day, as they have small stomachs and can’t eat a lot at once.

Overall, breeding Endler’s Livebearers is a rewarding experience. With the right setup and care, you can watch these beautiful fish thrive and grow.
