Denisoni Barb

Denisoni barbs are also known as the red-line torpedo barb, Denison barb, or roseline shark. These fish are active swimmers and get more and more color as they age, showing bright reds and yellows. We recommend a school of three or more. Roseline sharks are hardy and eat flake and live foods. A school of roseline sharks is a nice addition to planted tanks, peaceful community tanks, and larger species fish tanks, but these fish do require well-filtered aquarium water.

Quick Facts

Care Guide

Tank setup: These barbs grow large and swim fast, so give them lots of open space, strong filtration and a tight-fitting lid, since they can jump.

Feeding: Feed a quality flake or small pellet once or twice a day, only as much as they eat in a couple of minutes. They also enjoy frozen foods like bloodworms and brine shrimp.

Tankmates: Keep them with similar-sized, active fish such as rainbowfish, larger barbs, larger tetras, loaches and peaceful cichlids. Very small fish may be eaten or stressed.

Good to know: Denison barbs are fast swimmers that need strong filtration, lots of oxygen and a tight lid, since they can jump.
