BiologyFound in lakes and coastal rivers (Ref. 3236) and appears to tolerate a certain amount of salt (Ref. 78218). Occurs usually over soft, slightly muddy substrates or substrates with heavy layers of leafy detritus in deep, relatively quiet waters (Ref. 6868). Feeds on mollusks and small crustaceans (Branchiopods, Copepods, Ostracoda) which it digs from the substrate (Ref. 27935), and also on insects (Ref. 28714) and fish (Ref. 28714, 78218).
