    Found over sandy and muddy bottoms of coastal waters, bays, estuaries, and may ascend rivers into freshwaters (Ref. 9812, 44894). Adults inhabit brackish coastal lakes (Ref. 44894). Found in schools (Ref. 9812). Shoal-forming (Ref. 44894). They are omnivores, feeding mostly on benthic detritus, algae and small invertebrates. Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Spawn in coastal waters in summer and autumn, probably in estuaries (Ref. 9812, 27012, 28470, 28707, 28708).
