Gastromyzon farragus is a small gastromyzontid loach from swift hill streams in the Sadong River basin of southern Sarawak, Malaysian Borneo. It is dark brown with thin cream bars across the back and a red caudal fin, and is very close to G. ocellatus. One of the more commonly traded members of the genus, it often arrives in mixed shipments labelled 'Borneo sucker' or 'Hong Kong pleco', and needs clean, well-oxygenated water with strong flow.

Gastromyzon scitulus is a hillstream loach endemic to tributaries of the Sungai Sadong basin in southern Sarawak, Malaysian Borneo. One of the more commonly-traded members of the genus, it usually arrives in mixed shipments labelled 'Borneo sucker' or 'Hong Kong pleco' regardless of species. It forms a pair of cryptospecies with the very similar G. ctenocephalus, and intermediate forms of both mean identification can sometimes be tricky.
