Brevibora is a genus of small rasbora-like cyprinids from Sundaland, recorded in the atlas across Indonesia, Malaysia, and Thailand. The three species are diminutive schooling fish, 1–2 in, typical of the blackwater and peat-swamp streams that define much of lowland Sumatra, Borneo, and the Malay Peninsula - tea-colored, acidic water stained by tannins and low in dissolved minerals.
The eyespot rasbora (Brevibora dorsiocellata), named for the dark spot near its dorsal fin, is the species most likely to show up in the aquarium trade, kept in small shoals in soft, acidic blackwater setups alongside other Sundaland micro-fish. One species in the genus is assessed Endangered, which fits the well-documented conservation squeeze on Sundaland's peat-swamp forests - large-scale drainage and conversion for agriculture has destroyed much of this once-extensive habitat type across the region.
