Freshwater Fish
Roseline Shark.
The roseline shark is a torpedo-shaped fish with a bold red-and-black stripe, peaceful despite the name and far more demanding than it looks. Native to fast-flowing hill streams in India, it needs cool, well-oxygenated water with current — keep a school of six or more in a 55-gallon-plus tank.

Good tank mates
Despite the 'shark' name, the roseline shark is peaceful and community-safe, and it's best kept in an active group of six or more rather than singly. It pairs well with other lively, similarly-sized fish that enjoy current: larger tetras, barbs, danios, rainbowfish, and bottom-dwellers like larger corydoras. Avoid slow or very timid fish that its fast pace would stress, plus anything aggressive or large enough to eat it. It wants cool, oxygen-rich water with flow, so match it with fish that like the same.
Good to know
The roseline shark is native to fast-flowing hill streams in the Western Ghats of India, where cool, well-oxygenated water shaped its torpedo build and love of current.

Bronze Cory
Peaceful, armored bottom-dwellers that share compatible water parameters with Roseline Sharks and occupy an entirely different tank zone. Their armored plates protect them from any incidental contact with boisterous roselines, and they pose zero aggression or fin-nipping risk in return. This is a universally accepted community pairing with no documented compatibility problems.

Rosy Barb
Temperature range (64–75°F) aligns closely with Roseline Shark preferences (optimal 72–75°F), making it one of the best parameter matches available. Both are short-finned, active schooling barbs of comparable size, which removes the long trailing fin trigger that typically drives barb fin-nipping behavior. Kept in groups of 6+, they school actively alongside roselines without the chronic stress or harassment associated with more aggressive barb species.
