There are many similar-looking hillstream loaches in the genus Gastromyzon native to fast-flowing streams of Borneo. Several are black with small white spots. Their bodies act as suction cups to cling on to rocks, stones or vegetation in their fast-flowing habitat while their underside mouths rasp algae.
