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. While they disappeared from the wild, it remained in the aquarium trade because of artificial breeding by private fish farms for over three decades.

The fish was discovered by Somphong Lekaree (สมพงษ์ เล็กอารีย์) and Damri Sukaram (ดำริ สุขอร่าม) in 1959. Lekaree was an aquarium fish exporter while Sukaram was a fisherman for aquarium trade.<ref>Kittipong Jaruthanin (story) and Kamphol Udomritthiruj (photo), ตามรอย...

The specific epithet of this fish honors Aree Sidthimunk (Template:Langx), a researcher at Department of Fisheries, Ministry of Agriculture.

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.<ref>Loaches Online - Botia sidthimunkis vs Botia cf. nigrolineatas (Archived 4 December 2004 at web.archive.org)</ref>
