Feeding Ambush predator. Easily adapts to a diet of frozen food and pellets in the aquarium. May eat small bottom dwellers.
Furniture Inhabits clear, swiftly flowing forested streams with sandy or rocky bottoms; hides under submerged logs or rocks with some leaf litter in the swifter parts of the stream. The fish does appear to move about after dark, as it is often found wedged under cover during the day. Driftwood and rocks seem to be their favorite cover, so provide plenty of these.
Compatibility Can be kept with anything other than small bottom dwellers.
Breeding Not reported.
