Diet

Omnivorous micro-predator and grazer that thrives on high-quality flakes or micro-pellets, regularly supplemented with small live or frozen foods like daphnia, baby brine shrimp and mosquito larvae plus some spirulina or vegetable matter.

Community Compatibility

Peaceful nano livebearer ideal for planted community tanks with small, non-aggressive tankmates such as rasboras, tetras, Corydoras and shrimp that won’t nip fins or swallow adults.

Good to Know

Endler’s livebearers (Poecilia wingei) were rediscovered by Dr. John Endler in Venezuela’s Laguna de Patos in the 1970s and many modern strains, including Yellow Cobra, descend from those tiny endangered lagoon populations now maintained almost entirely in aquaria.

Gender Differences

Males are much smaller, slimmer and intensely coloured with neon patterns and a gonopodium, while females are larger, more rounded and mostly silvery or tan with a gravid spot when pregnant.

About the Yellow Cobra Endler Guppy

The Yellow Cobra Endler Guppy, a striking variant of Poecilia wingei, is one of those fish that immediately pulls your attention the moment it enters the tank. Its vivid yellow tones, contrasted by intricate cobra-like striping and patterning, give it an almost electric presence. Unlike more uniform fish, each individual carries a slightly different arrangement of markings, making every specimen feel unique and collectible. This variability is part of what keeps enthusiasts coming back—no two Yellow Cobras ever look exactly the same.

Originating from the Endler lineage, this fish carries the wild charm of its Venezuelan roots while showcasing the refinement of selective breeding. The cobra pattern itself is a hallmark of careful genetic selection, blending bold coloration with intricate, almost maze-like striping across the body and tail. The result is a fish that feels both natural and designer at the same time—wild energy shaped into a visually consistent aesthetic.

Behaviorally, Yellow Cobra Endlers are lively and constantly in motion, bringing a sense of energy and life to any aquarium they inhabit. They tend to occupy all levels of the tank, darting and weaving in a way that feels almost playful. This constant activity, combined with their bright coloration, makes them especially captivating for viewers. They are the kind of fish that turns even a simple tank into something dynamic and engaging to watch.

What truly sets the Yellow Cobra Endler apart is how it bridges the gap between wild-type fish and ornamental showpieces. It doesn’t rely on exaggerated fins or unnatural shapes to stand out—instead, it uses color, pattern, and motion. For hobbyists and creators alike, it’s a perfect subject: visually rich, genetically interesting, and endlessly photogenic. Whether seen in a planted aquascape or a minimalist setup, it consistently delivers visual impact far beyond its small size.
