    , Red Line Torpedo Barb


    Asia: Primarily from Kannaur, Kerala in India.

General Body Form:

    Slender and elongated torpedo shaped body with a slightly rounded belly.


    Body of gold or silver with red and black stripes running front to back and coming to a point at the nose. A red stripe runs through upper part of eye. Tail has 2 bright yellow slashes topped with Black. Dorsal fin has a Red swatch starting at the base and continuing along the top, thinning as it nears the end.


    A peaceful and extremely active schooling fish-especially when young, less so as adults. They will use all water levels (top , middle and bottom). Recommended in a school of 6 or more. These fish are omnivores and eat pretty much whatever is offered. Loves freeze-dried bloodworms and sinking shrimp pellets. Live food is a nice treat as well as fruits and vegetables. Denison Barbs require a large enough tank to allow sufficient swimming space, but appreciates plants and driftwood (or ornaments ) to swim in through and around. Use hardier plants as they will nibble at soft plants. Provide a lot of current. Ideally keep them with active fish of similar size, but they will work well in most community set-ups providing extreme size differences and no overly aggressive fish are present. Coming from swift flowing cool water at 59-77°F (15-25°C) the oxygen content is high and the water conditions in your tank should try to mimic this as much as possible with the use of powerheads, excellent filtration and maintenance practices. Although I would recommend a heater -if your house temp is stable they do not actually need a heated tank.



    Fast flowing mountainous streams.

Breeding:Sexing and breeding is unknown, I have not seen any reports of tank breeding.
