About

Hemigrammus unilineatus, the Featherfin Tetra, is a slender species from Trinidad and northern South America, displaying a crisp black lateral stripe and a distinctive white-tipped dorsal fin that flutters beautifully when the fish schools. Hardy and adaptable across a broad range of water conditions. Its active schooling behaviour and elegant finnage make it a charming community tank resident.

Care Guide

Keep in schools of 8+. Hardy and adaptable to a wide range of soft to moderately hard water. Feed flake, micro-pellets, and small frozen foods. Provide open swimming space with planted margins. The white dorsal fin tip creates a striking visual effect in large schools — keep in large groups for maximum impact.
