Kurzbeschreibung Morphologie | Morphometrie

A dark blue or black "ear" on an extension of the gill cover called the opercular flap; a prominent dark blotch at the base of the dorsal fin, close to the tail; typically olive-green backs, with a blue or purplish sheen along the sides; faint vertical bars may be present along the sides; breeding males may have more blue and orange coloration on their flanks (Ref. 44091).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Adults are found frequently in lakes, ponds, reservoirs and sluggish streams (Ref. 5723, 10294); occur primarily in reservoirs in Hawaii; preferably live in deep weed beds (Ref. 5723). Active mainly during dusk and dawn. They feed upon snails, small crayfish, insects, worms and small minnows (Ref. 5723). Young feed on crustaceans, insects and worms (Ref. 5723, 10294).
