The dwarf loach is found in the Mae Klong River and the Khwae Noi River in western Thailand. This species is endangered and is a protected species in Thailand. It was thought to be extinct in the wild until recently rediscovered in Sangkhla Buri.

The dwarf loach closely resembles Ambastaia nigrolineata , another Thai protected species, especially when the fish is fully grown. The difference is easily seen when the fish is still small. Juveniles of A. sidthimunki have dotted patterns while A. nigrolineata have horizontal lines on them. Furthermore, the chain pattern of A. sidthimunki develops in fish at a smaller size. [8]
