Purple Cobra Candiru — Cetopsis candiru
River myth turned real predator
The Purple Cobra Candiru is one of the most intense oddball predators you can keep. Long, slender, and built like a living blade, this South American catfish carries a smoky violet-to-charcoal body that can shift in tone depending on mood and lighting. Its elongated head and sharp, fang-like teeth give it a cobra-like appearance — a look that earned it its name.
Native to Amazonian river systems, Cetopsis candiru is not a timid scavenger. Unlike parasitic candiru species people talk about in myths, this member of the whale catfish family is an active carnivorous predator. It patrols the lower water column with purpose, using speed and precision to strike.

This catfish is striking in appearance and very active. It patrols the tank with purpose and shows interest in live prey. The color changes in different lighting are fascinating to watch. Requires a good-sized tank and consistent water parameters.

A unique addition to my aquarium. It doesn’t eat much but is always moving around. The violet hue is beautiful, especially under soft LED lights. Needs a bit of space and a good filter.

I was skeptical at first, but it’s a real showstopper. The cobra-like head and body movement are impressive. Feeds on small live foods and stays calm when not hunting.
