Roseline Shark / Denison Barb

Select Import

The Roseline Shark, also known as the Denison Barb or Red Line Torpedo Barb, brings striking color and constant movement to a spacious freshwater aquarium. A bright red stripe and bold black lateral line contrast against its silver body, creating an eye-catching display as the group swims together.

Despite the common name, Roseline Sharks are barbs rather than true sharks. They are social fish best kept in a school of at least six, with larger groups offering an even more impressive display.
