FEEDING ECOLOGY AND DIET
Feeds on aquatic plants, invertebrates, and fishes, occasionally conspecifics.
Spawns in late spring and early summer over male-constructed and guarded nests. The demersal, adhesive eggs hatch in three to four days. The male continues to protect the young as long as they remain in the nest area. Once they scatter, usually within a few days, protection ceases. They reach sexual maturity at three to five years.
