A short, deep-bodied, compressed fish. Scales large, dorsal profile straight from tip of snout to front of dorsal fin; dark marginal band on tail (Ref. 26938).
Occurs usually near vegetation in salt, brackish and fresh water (Ref. 86798). Inhabits hypersaline lagoons and connecting channels. Found on muddy bottoms in turbid waters (Ref. 5217). Omnivorous; consuming organic detritus and algae, as well as microcrustaceans, and dipteran larvae (Ref. 79012). Caught with fine-meshed nets. Very abundant and easily reproduced in captivity. Used as a forage fish in mariculture (Ref. 5217). Not a seasonal killifish. Is easy to maintain in the aquarium (Ref. 27139).
