Description
Adults inhabit cool, vegetated, sand or mud bottoms of lakes and ponds. Also in pools and backwaters of creeks and small rivers. Rarely found in brackish water. Feed on crustacean and insect larvae, eggs and larvae of fishes, snails, oligochaetes and algae. Preyed upon by kingfishers, herons, and mergansers and occasionally by fishes like Salvelinus fontinalis and Esox lucius. Males build, guard and aerate the nest where the eggs are deposited.
