Mating System

Endler’s Livebearers are livebearers, which means that females give birth to live young rather than laying eggs. The mating system of this species is characterized by the males courting the females through chasing displays. Once the female is receptive, mating occurs, and she will carry the developing fry internally until birth. Males may mate with multiple females, and females can store sperm to fertilize multiple batches of fry.

Pregnancy and Birth

The gestation period of an Endler’s Livebearer is relatively short, usually lasting around 28 to 40 days, depending on various factors such as water temperature and the female’s health. During this period, the female’s abdomen gradually expands as the fry develop inside her. When the time comes for birth, the female will release the fry into the water, and they will begin swimming and fending for themselves almost immediately. It is essential to provide plenty of hiding spots and floating vegetation for the fry to seek refuge and increase their chances of survival.



While Endler’s Livebearers are currently listed as “Least Concern” by the IUCN, there are still threats to their populations in the wild. One significant threat is habitat destruction, as human activities such as deforestation and water pollution impact their natural habitats. Additionally, the introduction of non-native fish species can pose a threat to their survival, as they may outcompete or prey on Endler’s Livebearers.

Conservation Efforts

To ensure the long-term survival of Endler’s Livebearers, various conservation efforts are underway. These efforts focus on protecting their natural habitats, conducting research on their biology and population dynamics, and promoting responsible aquarium trade practices. It is important for aquarium hobbyists to support these conservation endeavors by sourcing their fish from ethical and sustainable sources and promoting the responsible care and breeding of this species in captivity.

Tank Requirements

Tank Size and Setup

For keeping Endler’s Livebearers, it is recommended to provide them with a tank that has a minimum capacity of 10 gallons (38 liters). A larger tank, however, would allow for better swimming space and provide room for a small community of fish. Setting up the tank should involve creating a well-planted environment with both floating and rooted vegetation. This will mimic their natural habitat and provide plenty of hiding spots and territories for the fish.

Water Parameters

To ensure the well-being of Endler’s Livebearers, it is important to maintain appropriate water parameters in the aquarium. The water temperature should ideally be kept between 75°F to 82°F (24°C to 28°C), with a pH level ranging from 6.5 to 8.0. It is also crucial to regularly monitor ammonia, nitrite, and nitrate levels, as keeping these parameters within appropriate ranges is essential for the health and longevity of the fish.


Endler’s Livebearers are generally peaceful and can be kept with other non-aggressive fish species. They can coexist comfortably with other livebearers, small tetras, Rasboras, and peaceful bottom-dwelling fish like Corydoras catfish. It is important to avoid keeping them with larger or aggressive fish that may pose a threat or engage in fin-nipping behavior.



Endler’s Livebearers are omnivorous fish and have a relatively diverse diet. They will eagerly consume high-quality flakes or pellets specifically formulated for tropical fish. However, to maintain optimal health and vibrancy, it is recommended to supplement their diet with frozen or live foods, such as brine shrimp, daphnia, and bloodworms. These additional food sources provide essential nutrients and help mimic their natural diet.

Breeding Setup

Endler’s Livebearers breeding can be a rewarding experience for aquarium enthusiasts. To encourage successful breeding, it is recommended to provide a well-planted tank with plenty of hiding spots. Floating vegetation, such as Indian Almond leaves or moss, can be utilized to provide additional hiding places for the fry and to mimic the natural environment. Maintaining stable water conditions and ensuring proper nutrition are also essential for successful breeding.

Fry Care

Endler’s Livebearer fry are relatively self-sufficient and will begin swimming and foraging for food shortly after birth. However, to enhance their chances of survival, it is crucial to provide ample hiding spots and floating vegetation in the breeding tank. These hiding spots protect the fry from potential predators within the tank. Additionally, it is advisable to feed them with high-quality, finely crushed fry food and infusoria to ensure their nutritional needs are met.

Sex Determination

Distinguishing between male and female Endler’s Livebearers can be quite straightforward. Adult males are typically smaller and more colorful than females, with vibrant patterns adorning their bodies and fins. Females, on the other hand, tend to have a larger body size and display less vibrant colors. Females also have a more rounded abdomen, which may become noticeably enlarged during pregnancy. This simple visual observation can help determine the sex of these fish with relative ease.

Common Health Issues

Disease Prevention

Preventing disease is crucial for the overall well-being of Endler’s Livebearers. To minimize the risk of diseases, it is important to maintain optimal water quality by regularly testing and monitoring water parameters.

In the event that a disease does occur, prompt identification and proper treatment are essential. Seeking guidance from a knowledgeable aquatic veterinarian or an experienced fishkeeper is highly recommended. It is important to follow their advice and use medications specifically formulated for fish health. Additionally, providing a stress-free environment with excellent water quality and proper nutrition can greatly aid in the recovery process.

Final Thoughts

Endler’s Livebearer is a captivating fish species that showcases remarkable beauty and engaging behavior. Their colorful patterns and active nature make them a joy to observe in an aquarium setting. However, it is important to consider their conservation status and promote responsible care and breeding practices to ensure their long-term survival.
