Oreichthys is a genus of tropical barbs found in Thailand, India, Bangladesh, Myanmar (Burma), northern Malay Peninsula, and the Mekong basin in Laos. They are found in ditches, ponds, streams (both highland and lowland) and canals.[1] The genus Oreichthys (Smith 1933) was originally established to receive little fish collected in a small brook on Kao Sabap, an extensive mountain range near Chantaburi, Thailand.[2]

Physical description
All Oreichthys, with the exception of O. crenuchoides, possess a triangular-looking body, with the face being pointed. In O. crenuchoides, the body and face are more rounded. The last simple dorsal ray is flexible and smooth. Scale count is 23 in the lengthwise series and 7 in the transverse series. The tube-bearing scales of the lateral line are restricted to the first 6 or 7 scales anteriorly. The head is marked by numerous fine rows of pores, mostly in parallel groups on the snout, cheeks, interorbital space, and operuclar bones. Barbels are absent.
