Denison Barb (Puntius Denisonii) Fish Species Profile
The Denison Barb is long torpedo-shaped fish (hence one of its other popular names "Torpedo Barb") which grow up to 6 inches in length. Due to their larger size, an aquarium of at least 200 litres is recommended.
The Denison Barb is described as being mainly silverish with a greenish tinge that appears once mature. A black line which runs from the snout to the tail fin and is contrasted by an adjacent red line running from the nose to the midpoint.
The dorsal fin is edged in red, while the caudal fins exhibit prominent black and yellow stripes. It's a beautiful looking fish and a very active fish best maintained in groups.
The popularity of this beautiful fish resulted in intense overfishing of the wild stock, pushing them into becoming endangered. Thankfully they are now captively bread which has taken the pressure off of the wild population and reduced the selling price in the hobby.
There are also rarer gold and grey morphs of the Denison Barb which have been line bred for the inclusion in the fishkeeping hobby.

The Denison barb originates from Western India, mainly in the rivers Chalakkudipuzha, Chaliar, and Kallada. Denison barbs are now captively mass bread and are readily found throughout local fish shops around the world.
In the wild, the Denison barb feeds mainly on insects and water crustaceans as well as eating algae and plant matter. In an aquarium, the barbs will eat almost everything you provide, all types of natural and artificial food.
To ensure they remain in optimal health, you should supplement their diet with live and frozen food and some vegetable matter such as boiled broccoli.
