Also lives in still or gently flowing water of pools and side channels. A solitary species. Feeds  on mollusks, insects, prawns crustaceans and worms. Spawning period coincides with the rise of the monsoonal floods. Adults migrate upstream into shallow riffle zones where they spawn in pairs. The demersal eggs lodge in crevices on the bottom and hatch 2-3 days later. Aquarium Care: In the aquarium they tend to be less inclined to like company as they get older, and are very much a digger. Better suited to larger tanks of 4ft (120cm) or over with rocks and plants provided for cover. It has been reported that they are easily spooked in the aquarium. Best kept in small groups of 4-6 individuals. Diet: Snails, insects, prawns and earthworms.
