Description
The redside barb is a small fish with a slender, compressed, torpedo-shaped body. The adult size for both the sexes is maximum 7 cm. This species exhibits sexual dimorphism, which allows for easy identification of the sexes. It has two black spots: one at the base of the dorsal fin and one at the junction of body and caudal fin. There is a colored band from its eyes to the spot at the caudal fin. In mature males, the band has a distinct dark red coloration in the middle with a bronze-greenish-colored stripe above the red band. The eyes have a red-colored outer semi-circle. In females, the red is less pronounced and the bronze-colored band will be difficult to distinguish from its body scale color. The females has a slightly plumper body.
Habitat
The redside barb lives in hill streams, lowland swamps and dry zone rivers and tanks. They are benthopelagic and feed on green algae and detritus.{2,3}. They live on water with pH range 6.5 - 7.5 and dH 5-15.It is found abundantly in the river bank, lowland and hilly stream in Tripura caught mostly by the indigenous tribes
In the aquarium
Redside barbs are very active, fast swimmers and are very peaceful towards other tank mates. They will be attractive in a school of more than 6. They love moderate currents and swim against it. With a free space to dart around they would appreciate hiding spots between plants, driftwoods and rocks. In a planted tank they use to nibble the green algae from the leaves. They are non fussy eaters and accepts most of the prepared foods. In a school the most dominant male would be showing brilliantly colored red stripe with a greenish bronze colored upper band. It is not known about its breeding in the aquarium. Being of peaceful temperament they are suitable to most of the community aquaria.
Commercial importance
The redside barb is important in the aquarium trade {4}.
