Denison Barb / Roseline Shark (Sahyadria denisonii)
Quarantined barb for planted and community aquariums in Canada.
The Denison Barb, also known as the Roseline Shark, is a premium active schooling fish with a bold red stripe, black lateral line, and yellow-black tail markings. It is best suited to larger aquariums with strong filtration, good oxygenation, and open swimming space.
Why This Fish Stands Out
- Premium schooling fish with red-line and roseline pattern
- Peaceful but very active fish for larger aquariums
- Excellent movement fish for large planted or river-style displays
Aquarium Setup & Behaviour
Provide a long aquarium, strong filtration, good oxygenation, and open swimming space. This fish thrives in well-maintained environments with ample room to swim and school.

The Denison Barb adds a vibrant splash of color to my 80-gallon planted tank. It schools well and moves gracefully through the water. The red stripe is striking and the fish are active without being aggressive. I’ve had them for three months and they’re thriving.

Great addition to a river-style aquarium. The fish are lively and enjoy the open space. I paired them with tetras and Corydoras, and they coexist peacefully. A bit of space is needed, but worth it for the visual impact.

Ordered quarantined fish, and they arrived healthy. The red and black markings are very distinct. They swim in tight groups and bring energy to the tank. I’m happy with the purchase and the quality of the fish.
