FEEDING ECOLOGY AND DIET
Feeds both amidst vegetation and in open waters on small fishes and invertebrates. Primarily feeds at dawn and dusk.
Spawning occurs in late spring and early summer. Males make nests, sometimes near other males, in the substrate of weedy or rocky areas. Females may mate with several males. Females lay spherical, demersal, adhesive eggs singly or perhaps in small clumps. Males guard the eggs and young, which hatch in two to three days. Reach sexual maturity by two to four years old.
