Endler's Livebearer
Also known as: Poecilia wingei
Endler's Livebearer is a small, vibrantly colored freshwater fish closely related to the guppy but distinguished by its unique patterns and slimmer body. The Endler's Livebearer originates from Endler's Livebearer (Poecilia wingei) is native to the Laguna de Patos and surrounding freshwater lagoons and streams in northeastern Venezuela, particularly in the state of Sucre, where it inhabits shallow, vegetated, slow-moving waters with sandy or muddy substrates., reaches {'adult_size_cm': 3.5, 'adult_size_inches': 1.4} in captivity, typically lives 2.5, and is kept at {'celsius': 24, 'fahrenheit': 75}. Individual fish vary, so treat this as a general guide rather than a guarantee.

About the Endler's Livebearer
Endler's Livebearer is a small, vibrantly colored freshwater fish closely related to the guppy but distinguished by its unique patterns and slimmer body. Males display striking iridescent hues of orange, blue, green, and black, while females are larger and less colorful. They are prolific breeders, giving birth to live young every 24–30 days under optimal conditions. Their hardy nature and adaptability make them popular among both beginner and experienced aquarists.
Lifespan and health
Endler's Livebearers typically live 1.5 to 3 years in captivity, with exceptional individuals reaching up to 4 years under optimal care; females often have slightly shorter lifespans due to the energetic cost of frequent reproduction, which can occur every 3–4 weeks when well-fed and warm. Lifespan is strongly influenced by water quality, diet, and genetic lineage—wild-type strains tend to be hardier and longer-lived than highly inbred ornamental varieties. Common health issues include fin rot (often from poor water quality or aggression), ich (white spot disease) triggered by temperature fluctuations or stress, and internal parasites like nematodes, which may cause wasting despite normal appetite. Swim bladder disorders can occur from overfeeding or constipation, particularly in females carrying multiple broods. Preventive measures include maintaining stable parameters, quarantining new fish, avoiding overstocking, and providing a varied diet; prompt treatment with appropriate medications (e.g., copper-based for ich, antibiotics for bacterial infections) is critical due to their small size and rapid disease progression.

Care and tank setup
Endler's Livebearers require a minimum tank size of 38 liters (10 gallons) for a small group, though 57–76 liters (15–20 gallons) is recommended for a stable population with room to swim and breed. The tank should be densely planted with fine-leaved species like Java moss, hornwort, or guppy grass to provide hiding spots for fry and reduce stress, while open swimming areas should be maintained. A gentle filter with low flow is ideal, as strong currents can exhaust these small, active fish; a sponge filter or adjustable hang-on-back unit works well. Water parameters should be kept stable: temperature between 24–27°C (75–81°F), pH 7.0–8.0, and hardness between 10–25 dGH. Weekly water changes of 20–25% are essential to maintain low nitrate levels (<20 ppm), as Endlers are sensitive to poor water quality despite their hardiness. Substrate can be fine gravel or sand, and lighting should be moderate to support plant growth without encouraging excessive algae. Feeding should occur 2–3 times daily with small amounts of high-quality flake or micro pellet food supplemented 2–3 times per week with live or frozen foods like brine shrimp, daphnia, or bloodworms to enhance coloration and breeding vigor. Overfeeding must be avoided, as uneaten food decomposes quickly and spikes ammonia. Fry can be fed infusoria or powdered fry food for the first 3–5 days, then transitioned to baby brine shrimp.
