Remarks | Occur in lentic and lotic freshwater (Ref. 7300); also found in coral reefs (Ref. 58534). Found over shallow sandy bottoms, in the vicinity of river mouths. Enter estuaries and rivers (Ref. 1479). Scale-eating behavior was suggested to originate from modified predation and modified parasite removal (Ref. 28733). Juveniles common in sandy intertidal areas. Omnivorous (Ref. 7300), feeding on fishes, insects, algae, and sand-dwelling invertebrates (Ref. 9710). Coastal.
