Facultative air-breathing in the genus (Ref. 126274); Live in the margins of lakes and streams, usually in rocky areas or around vegetation and debris. Bottom-dweller in shallows of lakes and inlet streams over rocky substrates. Often sheltering in crevices under rocks, woody debris or among aquatic plants. May also occur in deeper lacustrine waters. A nocturnally active, seldom seen species. Breed in summer (December-January), releasing demersal eggs among rocks at lake margins which hatch in two weeks. Juveniles swim in midwater feeding on plankton, and colonise the bottom after about six months. Sexual maturity is attained at the end of the first year; the maximum life span is probably about three years (Ref. 44894). Feed on insects, small crustaceans, algae and eggs of other galaxiids.
