The Endler’s livebearer is commonly found in South and Central America. Most of these fish thrive in Venezuela’s Paria Peninsula.

The fish’s natural habitats are unique due to their water chemistry, which has gradually shifted from brackish to freshwater.

Endler’s livebearers and their natural habitat have become threatened by human activity and water contamination, but the fish are not yet listed as an endangered species.

Only one of the four lakes that served as the fish’s original natural habitat remains. Otherwise, the fish can only be found in captivity.

Adult Size and Lifespan

The size of the Endler’s livebearer varies, ranging from 2 to 6 inches

The livebearer generally lives between three and seven years. An Endler guppy typically lives two to three years. Males often live longer than females.

Other factors, like the quality of care and heredity, also determine lifespan. To extend your fish’s lifespan, provide your fish with a diet rich in nutrients and a tank setting that is conducive to good health.


Endler’s livebearers can easily be found at common pet stores. Depending on color, size, and texture, an Endler’s livebearer fish ranges from $2–$6.

Females have a rounder belly and are typically tannish-silver in color, growing to a length of 1.8 inches.

Colors, Patterns, Fins, and Sex Differences

Endler’s livebearers appear in a wide variety, all with different characteristics. Different varieties of fish can also be bred together to create new colors and appearances.

Class N: Class N is the purest type of species, originating from fish living in the species’ natural environment.

Class P: Although its origins are uncertain, Class P fish are virtually identical to Class N fish.

Class K: Fish in the Class K category are hybrid and crossbred fish found in pet stores.

Typical Behavior

Endler’s livebearers are highly active swimmers and enjoy exploring their surroundings. The fish love to greet and interact with visitors. However, the fish sometimes nip at the fingers of visitors who put their hands in the tank.

The males are usually more reserved in nature, while the females are more aggressive.

Habitat and Tank Setup

To replicate the fish’s natural habitat, add algae and plants to the tank. You may also add small pebbles or sand grains. Plants are important because they also act as a source of food.

Floating plants are a good choice, as well as stemmed plants that extend above the water’s surface.

Tank Requirements

Endler’s livebearers require at least a 10-gallon tank. A 20-gallon tank is even better, giving the fish more space to swim around, especially if there are other tank mates.

Make sure your tank has a lid, as these fish are known to jump out of the tank.

Common Endler’s Livebearer Health Issues and Diseases

Livebearer fishes often suffer from the most common fish disease, ich. This condition is characterized by white spots and is more common when fish are under stress. To prevent ich, keep your tank’s water within the correct parameters, monitoring temperature and ammonia levels.

Parasites, fungi, and bacteria caused by overpopulation and higher ammonia levels can also affect these fish. To prevent these problems, make sure not to add too many fish to your tank.

Tank Mates

Endler's Livebearer tankmates

Endler’s livebearers are best kept with tank mates of the same species. However, the following types of fish can also be good tank mates.

  • Cherry barb
  • Ember tetra
  • Dwarf gourami
  • Honey gourami
  • Neon tetra
  • White Cloud
  • Corydoras catfish
  • Glassfish
  • Glowlight tetra

Diet and Feeding

As an omnivore species, Endler’s livebearers can eat a variety of foods, including algae, bloodworms, brine shrimp, and fauna. The livebearers are not picky eaters.

You may also feed them flaky and frozen food, pellets, and live meals.

However, the fish has a small mouth opening, so you need to make sure the fish’s feed is small enough. Crush larger feed into smaller pieces before feeding.

Give the fish only a little quantity of food per feeding.

Breeding the Endler’s Livebearer

Breeding Endler’s livebearers are usually easy compared to other fish species. These fish are almost always raised in captivity, making breeding much easier.

To breed, simply keep male and female livebearers in the same tank. However, make sure to keep more female fish than males in the tank to avoid the same female fish getting pregnant and becoming stressed.
