Endler’s Livebearer – scientifically known as the poecilia wingei – is a beautiful species of freshwater aquarium fish. It is known as the livebearer because this fish gives birth to a baby fish instead of laying eggs. It is a trait that is seen only in a few genera of fish. This makes it a very unique fish species, but it is not the only thing that is unique about this fish. It is also a very beautiful, and colorful fish species. In aquariums, it is known with multiple names such as Endler’s, and Endler’s Guppy. It belongs to the genus of fish known as Poecilia.

These fish are known as guppies because the original Engler’s Livebearer species can breed with guppies and produce colorful offspring. These colorful offspring are known responsible for the popularity of the fish. A lot of fish keepers want to have them in their tanks. Also, it is a fish species that is known for being an active breeder. According to data collected by researchers and fish keepers, the average birthing time of the Endler’s Livebearer is about 23 days. They produce new offspring every 23 to 24th days. This is something that has helped this breed survive in captivity because, in the natural habitats, their population was declared under the threat of extinction. Below is complete information about this fish and how to keep it in your tank.

How To Select Tank Companions?

Endler’s Livebearer is one of the most beautiful fish species that comes with a fluorescent color combination. As these look very beautiful, a lot of fish keepers want to keep them in a separate tank to enjoy their beautiful appearance. But if you want to pair them with other species, you can also do that. The Endler’s Livebearer is a very peaceful, joyous, and social fish species that can get along with any of the smaller members of the tank. They do not do well with larger and more aggressive fish species, also some small aggressive fish species are not meant to be in the same tank with the Endler’s Livebearer.

The list above contains a list of the possible tank mates for the Endler’s Livebearer, but if you want to pair them with other fish species, you can do that as well. But you will need to select the tank mates with great care. Because these fish are small and defenseless, you must select a tank mate that is suitable for them, and that is also compatible with them in terms of environmental conditions. To decide if Endler’s Livebearer can live with any other fish, you need to check three things about the other fish species. Here are further details about this.

First, you need to make sure that the species of fish you are selecting for the tank of Endler’s Livebearer, is not an aggressive fish species. This is a very important factor because the lifespan and quality of life of your Endler’s Livebearer fish would depend on it. There are a lot of fish species that are peaceful, and social. You need to select a species that shows no signs of aggression towards any other fish species, whether it is small or large.

Size is the second most important factor here because size determines whether a fish can live with the Endler’s Livebearer or not. There are a lot of fish species that can live with other fish species peacefully, but when you put them in a tank with smaller fish, they would become aggressive and would try to attack the smaller fish. You can prevent this from happening by selecting the fish of appropriate size. Make sure that the fish is not too big to eat the Endler’s Livebearer or too small for them.

Living conditions are the third most important factor when selecting a tank mate for the Endler’s Livebearer. This is important because you cannot select a tank mate that can not live within the same environment or living conditions as the Endler’s Livebearer. For example, the Endler’s Livebearer is a freshwater fish species, you cannot pair it with a marine or saltwater fish species. Because the hostile environment will affect other fish species. For these reasons, you need to make sure that you select a small fish, that has peaceful nature, and that can live in the same tank as the Endler’s Livebearer.

Apart from this, you may also have to look for a few factors. For example, the Endler’s Livebearer is an active breeder, which means that they breed a lot. So, if you are not planning on breeding them, you should not introduce any species of fish that can spawn with them. For example, the Guppies are a common mate for the Endler’s Livebearer. So, you should not put them in the same tank unless you want them to spawn and breed. It will help you create new varieties and genetically mutant Endler’s Livebearer subspecies.

Species Overview

The Endler’s Livebearer is one of the most unique fish species, from its coloration to body shape, and its breeding habits, everything is unique and rare about this fish. For example, the coloration of the bodies of Male and Female Endler’s Livebearers are different. Male has a more fluorescent appearance, and colors, while the females have a dull, and silver appearance. Male use their appearance to attract females for spawning and breeding in the tank. You will notice this behavior more often if your tank is full of opposite genders of Endler’s Livebearer fish.

The Endler’s Livebearer is from the genus of Poecilia. It is a genus that also contains other fish species such as mollies, and guppies. Due to this genetic similarity, the  Endler’s Livebearer fish can breed with guppies and mollies. According to researchers in genetics, the species of  Endler’s Livebearer is not an actual species. They are the same as the Guppies, but due to breeding with other species, Guppies’ genetic material changed and a new subspecies was born.

But researchers wanted to conserve the population of this species, hence it was given a separate name and status as a separate fish species. It is native to Laguna de Patos, which is in Venezuela. Also, the researchers say that its natural habitat has been destroyed and this fish is prone to becoming extinct. Hence it was declared an under-threat species of fish. As it is a colorful fish species, its popularity grew and it became a common aquatic fish. This is helping in the conservation of this species. This fish is capable of surviving in a tank environment and can breed quickly, which is helping this species successfully survive in tanks. 


It is one of the most colorful fish species, with a very unique appearance. The bodies of male Endler’s Livebearer are covered with different types of fluorescent colors. Meanwhile, the bodies of females are physically similar to the male, but they do not have a colorful appearance. The bodies of female Endler’s Livebearer are dull and silvery in color. Most Endler’s Livebearers grow up to 1.5 inches. If you provide them proper care, some can reach 2 inches in length. Anything larger than 2 inches would be a rare incident. Also, if you do not provide the proper care, the size of this fish can be smaller than 1.5 inches.

As mentioned above, it is not a single species of fish, but a group of fish that come from Guppies, but is known as a separate species. As they can breed with more than one fish species, they are capable of creating multiple varieties of fish. Each of these varieties can have different shapes, sizes, and colors, but in most cases, only the color is different while the shape and size remain the same. Here is a list of a few popular aquarium varieties of the Endler’s Livebearers.

  • Emerald: This Endler’s Livebearer is known for having a greenish fluorescent appearance.

  • White Peacock: The white peacock is also a color variation of the Endler’s Livebearer.

There are many other variants, you can ask your aquarist to help you find the one that you want.


This fish is native to the Laguna De Patos in Venezuela. The genetic make-up of this fish suggests that it is the same species as the Guppies but with more colors. This coloration happened because the guppies were breeding with other species of fish from the same genus in their natural habitats. This led to the creation of a subspecies that has become so popular that it has been given a separate name. It became a very popular aquarium fish because of its beautiful fluorescent appearance.

Natural Habitat

Taller tanks have a low surface area and that can cause oxygen shortages in the tank. You can only prevent this by making sure that you select a tank with the right size and dimensions.

Tank Setup

After you are done with the selection of an appropriately sized tank, it will be time for you to start creating a tank setup for the Endler’s Livebearer. For this purpose, you need to know the living conditions of Endler’s Livebearer in their natural habitat. You need to start with knowing more about their natural habitat and create a tank setup that is similar to their natural habitat. When you are creating a tank setup, you need to start from the bottom layer of the tank. There are a lot of different types of substrates that you can use.

It would be better to use soft treated sand, refined gravel, and a layer of fine-grained substrate. This would act as a bed underwater for your fish where they can come to find food, hide, and explore the bottom layer. After doing this, you need to find some aquatic plants that are suitable for your fish and that can produce more oxygen. After that, add them into the tank and once you are done with that, you can put some decorations, and caves inside the tank to make the habitat more interesting for the fish.

Water Conditions/Parameters

There are some parameters and water conditions that you need to control and maintain before putting your fish inside the tank and while your fish is in the tank. These parameters include acidity, temperature, and hardness of the water. Apart from this, filtration, lighting also needs to be maintained properly. Here are the recommended parameter ranges that you need to maintain.

  • The temperature is at 64°F to 84°F.
  • Acidity level at 5.5 to 8.0, try maintaining neutral.
  • The hardness of the water at 10 to 30 KH.

To maintain the temperature in your tank, you will need to put in a temperature sensor, and controller devices in the tank. These devices are available for tanks of all sizes and are very easy to use. It will allow you to directly monitor the temperature and make changes according to the season. For example, if it is too hot, you can add ice cubes to lower the temperature while if it is too cold, you can heat the water.

A filtration system is also one of the important systems that allow you to cycle the water in the tank and provide more oxygen to the tank of fish. Also, the Endler’s Livebearer needs movement in the water to breathe and swim. Apart from the filtration system, you also need digitally controlled lights for your tank to make sure that they light up during the day and turn off during the night. Additional items that you may also need to use include a tank lid to cover the tank.

Water Source

According to expert fish keepers, you can use the water from any freshwater resource, but you will have to make sure that the water is safe for the fish. You can do it using the water quality tests. If there are any harmful elements inside the water, you should remove them first before using the water.

They are not territorial, but male members sometimes show aggression, especially when the female is pregnant.

But they do not attack any member of the tank. Also, if your Endler’s Livebearer is being intimidated by other fish, it would run and hide instead of fighting. These fish are very active breeders, so you will notice them spawning every few weeks, but this can be prevented by only using males or females exclusively and not using both of them in the same tank.

Breeding Endler’s Livebearer

From the discussion above, you may have noticed that it is one of the easiest fish species when it comes to breeding. They do not lay eggs and carry their babies inside their belly for three to four weeks. After that, they give birth to the baby and start spawning once again. This quick breeding behavior allows you to successfully breed them. You do not need a special tank for them to breed. You just need to introduce a healthy amount of males and females in the same tank and wait for them to acclimate and start spawning.

Eggs and Fry Care

When a female Endler’s Livebearer gives birth, she can give birth to more than 30 Fry. The females do not protect these small creatures and might even try to eat them as food. So, it is better to remove the male and female from breeding tanks. It will take a few weeks for the Fry to be able to defend themselves and find food for themselves. Until then, you can feed them the food that is developed for them.

Diet of Endler’s Livebearer
