Puntigrus

Puntigrus anchisporus is a small cyprinid endemic to Borneo, recorded from Kalimantan in Indonesia and much of Sarawak in Malaysia. One of the four-barred species once called the 'Puntius tetrazona group', it has a complete lateral line, a black dorsal fin with a red outer band and red pelvic fins. It occasionally appears in the hobby, but the trade relies largely on commercially-produced 'tiger barbs' of questionable origin.

Puntigrus navjotsodhii is a small cyprinid known only from the upper Katingan and Barito river basins in Central Kalimantan, Indonesian Borneo. The type series came from a small clear-water hill stream of riffles and deeper pools over sand, gravel and rocks. Among the four-barred Puntigrus species it has broad black bars up to five scales wide, black lips and almost entirely red pelvic fins in life.

Puntigrus partipentazona is a small cyprinid recorded from numerous river basins in Vietnam, Cambodia, Laos, Thailand and Peninsular Malaysia. It is easily told from congeners because the dark blotch on its dorsal fin extends onto the body. Typically found in heavily vegetated parts of rivers and sluggish streams, it is generally peaceful, though rival males continually battle for position within the group.

Puntigrus pulcher is a small cyprinid endemic to the Indonesian part of eastern Borneo, with records from the Kayan and Mahakam rivers. Considered a synonym of P. anchisporus for decades following Alfred (1963), it was revalidated by Kottelat and Tan (2011). It has an incomplete lateral line, an entirely black dorsal fin and black pelvic fins, and occasionally appears in the hobby, though the trade relies largely on commercially-produced 'tiger barbs'.

The tiger barb, Puntigrus tetrazona, is a small cyprinid probably endemic to central and southern Sumatra, Indonesia. Among the most ubiquitous species in the aquarium trade, it is seen mostly as commercially-produced fish and ornamental strains, and wild examples are rarely traded. The identity of the 'aquarium' tiger barb is the subject of ongoing confusion, and many farmed fish are weak or deformed through inbreeding.
