Endler's Livebearer (Poecilia wingei) is a small, colorful, and popular freshwater fish native to Venezuela, specifically the Laguna de Patos and associated waters. They belong to the family Poeciliidae and are closely related to guppies, often interbreeding with them in the wild.
These fish are named after Dr. John Endler, an ecologist who extensively studied their behavior and distribution.
Endler's Livebearers are known for their striking colors, vibrant patterns, and active swimming behavior, making them a favorite among aquarium enthusiasts. They are relatively easy to care for and are suitable for both beginners and experienced aquarists.
In the wild, Endler's Livebearers inhabit slow-moving or still waters with dense vegetation, where they feed on small invertebrates. They are livebearers, meaning they give birth to live fry rather than laying eggs.
Water Size
One individual Endler's Livebearer typically requires a minimum tank size of 5 gallons (approximately 19 liters) due to their small size.Recommended Water Parameters
Temperature: 72-82°F (22-28°C)pH: 6.5-8.0
Water Hardness: 5-20 dGH
Ammonia, Nitrites, and Nitrates should be kept at minimal levels through regular water changes and maintenance.
Water Changes
Regular water changes of 20-25% every 1-2 weeks help maintain water quality and promote the health of Endler's Livebearers.Schooling Behavior
Endler's Livebearers are not strict schooling fish but are social and thrive when kept in small groups. A small school of these fish adds vibrancy to the aquarium.Air Pump
An air pump is not typically necessary, but it can improve oxygen exchange and water circulation, particularly in tanks with limited surface agitation.Filter
While not absolutely necessary, a filter is recommended to maintain water quality by removing waste and toxins.Tank Cover
A tank cover is not strictly necessary, but it can prevent fish from jumping out and provide added security.Aquarium Lighting
While not necessary, aquarium lighting can enhance the colors of Endler's Livebearers and promote plant growth if live plants are present in the tank.Heater
A heater may be required to maintain a stable water temperature within the recommended range, especially in cooler environments.Substrate
They are flexible regarding substrate and can thrive with various types, including sand, fine gravel, or planted substrates.Interaction with Plants
Endler's Livebearers typically interact well with live or artificial plants in the aquarium. Plants provide shelter and a natural environment.Feeding Regimen
They are omnivorous and should be fed a balanced diet consisting of high-quality flakes or pellets designed for small tropical fish. Supplement their diet with occasional live or frozen foods like brine shrimp or daphnia. Feed them 2-3 times a day, only what they can consume in a few minutes.Lifespan
Endler's Livebearers have an average lifespan of 2-3 years, although with proper care, some individuals can live longer.Interesting Facts
- Endler's Livebearers are often hybridized with guppies, leading to unique and colorful strains known as "Endler-Guppies" or "Endler's Guppies."
- These fish are named after Dr. John Endler, who conducted extensive research on their natural behavior and distribution in the wild.
- They are sometimes called "the orchid of the fish world" due to their striking and varied coloration, which has led to the development of numerous selectively bred strains.
