Barbs are a group of active, colourful freshwater fish belonging to the subfamily Barbinae within the large carp family Cyprinidae, and they are among the most popular choices for community aquariums in the UK. The group includes a wide variety of species, from the widely kept Tiger Barb (Puntigrus tetrazona) and the Cherry Barb to larger species such as the Tinfoil Barb. All species share the characteristic barbels — small whisker-like sensory organs near the mouth — that give the group its common name. Barbs are native to freshwater habitats across Asia and Africa, preferring soft, slightly acidic to neutral water with good aeration.
Barbs are schooling fish and do best when kept in groups of at least five or six individuals; solitary or small groups can become nippy and stressed. Within a school they establish a natural social hierarchy, and this interaction keeps even the more boisterous species occupied and less likely to harass tank mates. They are hardy, adaptable fish that tolerate a range of water conditions, making them well-suited to newcomers to the hobby as well as experienced aquarists. Most species thrive in a planted aquarium with open swimming space, a temperature between 22 and 26°C, and a varied diet of flake food, micro pellets, and live or frozen invertebrates. Their speed, colour, and lively group behaviour make barbs a rewarding and visually striking addition to any community tank.
