Ecology of Mastacembelus armatus
 
Main Ref. Lim, P., S. Lek, S.T. Touch, S.-O. Mao and B. Chhouk, 1999
Remarks Lives in highland streams to lowland wetlands (Ref. 57235). Usually found in streams and rivers with sand, pebble, or boulder substrate. Seldom leaves the bottom except when disturbed. Also occurs in still waters, both in coastal marshes and dry zone tanks. Sometimes stays partially buried in fine substrate. Enters flooded forest (Ref. 9497). Reported to occur in areas with rocky bottoms in the Mekong mainstream during the dry season, but enter canals, lakes and other floodplain areas during the flood season (Ref. 37770). Forages at night on benthic insect larvae, worms and some submerged plant material (Ref. 12693). Common during the summer months. Recorded as having been or being farmed in rice fields (Ref. 119549).
