The Endler Guppy (Poecilia wingei), often called Endler's Livebearer, is a vibrant, small freshwater fish closely related to the common guppy (Poecilia reticulata). Endlers are prized for their neon-like coloration, compact size, and lively behavior. They are ideal for nano tanks, breeding projects, or aquascaped aquariums.

Common Name | Endler Guppy, Endler’s Livebearer |
Scientific Name | Poecilia wingei |
Family | Poeciliidae |
Origin | Laguna de Patos, Venezuela |
Type | Livebearer, closely related to guppies |
Lifespan | 2–3 years |
Size | Males: 1 in (2.5 cm), Females: 1.5 in (3.8 cm) |
Feature | Endler Guppy | Common Guppy |
---|---|---|
Size | Smaller | Larger |
Coloration | Brighter, neon-like | Wide color range |
Fins | Shorter, sleeker | Often elaborate and long |
Hybridization | Can interbreed with guppies | Can hybridize with Endlers |
Wild Types Exist | Yes (true wild strains exist) | True wild guppies are rare |
Wild Type: Green, orange, black patterns (especially in males)
Selective Strains:
Tiger Endler
Blue Star Endler
Black Bar Endler
El Silverado Endler
Red Flame Endler
Females are usually silver-gray with faint patterns.
Parameter | Ideal Range |
---|---|
Tank Size | 5–10 gallons minimum (larger for colonies) |
Water Temperature | 72–82°F (22–28°C) |
pH Range | 6.5–8.0 |
Water Hardness | Moderate to hard (8–20 dGH) |
Filtration | Gentle (sponge filter ideal) |
Plants | Live plants like Java moss, Hornwort, Guppy grass |
Lighting: Moderate; enhances color display.
Tank Lid: Required – Endlers may jump.
Temperament: Peaceful, highly active
Schooling: Males chase females constantly—best kept in ratios of 1 male : 2–3 females
Tankmates: Compatible with:
Small rasboras (e.g., Chili, Harlequin)
Dwarf shrimp (Neocaridina)
Corydoras
Otocinclus
Avoid fin-nippers or large fish
Type: Omnivore
Staple Diet:
High-quality micro pellets or flake food
Supplements:
Live/frozen: baby brine shrimp, daphnia, microworms
Vegetables: blanched spinach, spirulina flakes
Feeding: Small portions 1–2x daily; avoid overfeeding to maintain water quality.
Common Issues | Prevention/Treatment |
---|---|
Ich | Avoid sudden temp drops, quarantine new fish |
Fin Rot | Maintain clean, well-oxygenated water |
Swim Bladder Disease | Caused by overfeeding or poor water |
Stress from chasing | Maintain proper sex ratio and space |
Lifespan: 2–3 years on average; longer in stable tanks with good genetics
Breeding Type: Livebearers (no eggs; give birth to fry)
Gestation: ~23–28 days
Fry Count: 10–30 fry per birth
Breeding Tips:
Males breed constantly—provide hiding places for females
Plants like Java moss or spawning boxes help fry survive
Adults will eat fry—separate or heavily plant tank
Hybridization with guppies is common—not recommended if preserving pure Endler genetics.
Pros | Cons |
---|---|
Beautiful neon colors | Very small – can be eaten by larger fish |
Peaceful and great for nano tanks | May hybridize with guppies |
Easy to breed | Males may harass females without balance |
Hardy and beginner-friendly | Prone to overpopulation in mixed colonies |
Trait | Info |
---|---|
Size | M: ~1 in, F: ~1.5 in |
Lifespan | 2–3 years |
Water Temp | 72–82°F (22–28°C) |
Best Setup | Planted nano tank or colony tank |
Diet | Omnivore – high variety recommended |
Behavior | Peaceful, energetic, easy to breed |
Tankmates | Small peaceful species |
Pure Endler strains are kept by breeders to preserve genetics.
Hybrid Endlers (crossed with guppies) may have more variety but lose original traits.
Reputable breeders often label fish as "N-Class" (pure), "K-Class" (hybrid), or "P-Class" (pet quality).
