Denison Barb

Also known as the Red Lined Torpedo Barb and the Rose Line Shark, the Denison Barb is easily identified by its striking coloration. These fish have a slightly longer body than most Barbs and their bodies sport several different colors. Yellow and black accents adorn the tails of Denison Barbs and their dorsal fins are tipped with red. These fish also have a black line running along the length of their silver bodies with a red stripe through the eyes.

Tank Set-up

Denison Barbs are peaceful fish, unlike some other species of Barb. These fish can be safely kept in a large community tank and they thrive best in groups with at least eight of their own species. Denison Barbs originate in the swiftly flowing streams and rivers of southern India. Therefore, they will be able to tolerate some degree of current in the aquarium. These fish tend to prefer cooler water temperatures and enjoy densely-planted tanks decorated with pieces of bogwood to imitate their natural habitat.


These Barbs are omnivores in the wild, feeding on insects and invertebrates as well as algae and other plant matter. Denison Barbs should be offered a staple diet of high-quality flakes or granules along with small live and frozen foods such as bloodworms, Artemia and Daphnia. This diet should be supplemented with vegetable matter such as algae flakes and blanched vegetables. Feed a diet consisting of a variety of foods on a regular basis to promote the best health and coloration.


There are few known cases in which Denison Barbs have been successfully bred in the home aquarium but it is believed that a gradual lowering of the pH in the breeding tank may trigger spawning. Other studies suggest that these fish may be more inclined to spawn in large groups rather than pairs. The addition of bogwood to the breeding tank may also help to encourage spawning behavior.
