Adults occur mainly along weedy bays and backwaters, entering brackish water and to a limited extent, fresh water (Ref. 3814). They feed along the bottom, primarily on diatoms, worms and crustaceans by sucking in the prey with a pipetting action (Ref. 27549). Males build, guard and aerate the nest where the eggs are deposited (Ref. 205).
