Inhabits lakes, ponds, pools of creeks, and rivers. Also found in brackish water and in salt lakes. Most commonly found in clear water near vegetation; tends to shoal near the shore during spring (Ref. 9988, 10294). Feeds on immature insects, larger invertebrates, fishes and fish eggs during the day. Preyed upon by fishes and birds (Ref. 1998). Spawns between February and July in the northern hemisphere and between August and October in the southern hemisphere (Ref. 10999). Neither anterolateral glandular groove nor venom gland is present (Ref. 57406). Marketed fresh or frozen; eaten pan-fried, broiled or baked (Ref. 9988).
Nonobligatory plant spawner.
