Open encyclopedia reference
Ambastaia nigrolineata is a vulnerable species of loach found in the Mekong basin in Southeast Asia and China. It occurs in clear, fast-flowing riffles and hillstreams with moderate currents and substrates composed primarily of sand. It is known to feed on insect larvae and other benthic organisms.
Ambastaia nigrolineata reaches 8 cm (3.1 inches) in standard length. It is sometimes seen in the aquarium trade, but it has historically been confused with the only other species in the genus, the similar A. sidthimunki.
