Siamese algae eater
The Siamese algae eater (''Crossocheilus oblongus'') is a species of freshwater fish in the carp family, Cyprinidae. This bottom-dwelling tropical fish is found in mainland Southeast Asia, including the Chao Phraya and Mekong basins as well as the Malay Peninsula. Its natural habitats are streams and rivers as well as flooded forests during the rainy season. The Siamese algae eater should not be confused with the Flying fox (''Epalzeorhynchos kalopterus'') or the False siamensis (''Garra cambodgiensis'').
==Description==
The Siamese algae eater has a black horizontal stripe extending from opercle to tail. The stripe can fade to camouflage the Siamese algae eater against its surroundings. Genuine ''Crossocheilus siamensis'', without maxillary barbels and with deeply fringed V-shaped upper lip are rarely encountered in the aquarium trade.
Closely related is the Red-algae eater ''Crossocheilus langei'', a species that is widely sold as the Siamese algae eater. It has a bright brownish elongate body with a slightly flat belly. It has a prominent brown-black horizontal stripe extending from nose to tail. This fish may grow to measure up to 16 centimeters. It possesses small maxillary barbels and an unfringed shallowly arcuate upper lip. Two other similar species are traded as Siamese algae eaters, namely ''Crossocheilus atrilimes'', a species that prefers Java moss than red algae, and an undescribed species of ''Crossocheilus''.〔
