Appearance and Identification

A tiny, rare African barb from the Congo, with a dark stripe through the nose. It prefers cool, soft water, and tends to be expensive when found.

Behaviour and Tankmates

Active and social, and most settled when kept with its own kind.

Keep a group of at least 6, and more if you can. Larger groups are calmer and show better colour and behaviour.

Not territorial, although males may spar and display.

Suits a community of similar-sized, peaceful fish that like the same water. Avoid large predators, which will treat it as food. It may eat baby shrimp.
