while the caudal fin may be plain or have dark margins. They are sexually dimorphic with the females having fuller, rounder bellies than the males, the males develop a red inside of the mouth during the spawning season and both sexes develop tubercules on the head and snout when breeding, although these are more obvious in the males. They grow to 15 cm standard length.

Habits and ecology

The Cambodian logsucker lives in rapidly flowing, small to medium sized streams with rocky beds. In submontane to hill regions, it may also occur in larger or lowland rivers. At the start of the monsoon, it moves into floodplains or paddy fields where it breeds. The fry are cared for by the parents until they are juveniles, at which point they return to the streams. It feeds on periphyton, phytoplankton and some insects. It is sociable in the wild, forming hierarchies in loose shoals. To settle disputes, the males charge each other, flare their fins, become paler in colour and extend their rostral processes.

Human use

The Cambodian logsucker is eaten by some local humans, especially when spawning. It is common in the aquarium trade, but must be hormonally induced to breed in captivity.
