Euryhaline, found among detritus or vegetation over sand or mud, within a temperature range of 8° to 24°C. Probably an amphidromous species (Ref. 51243) but migratory behavior needs verification. Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Early free-living young measure 23 mm TL (Ref. 6733).
Females lay 10-60 eggs into a brood pouch on ventral surface of tail of males. Males fertilize the eggs as they enter the pouch. Eggs incubate in the male´s brood pouch for about 20-32 days, depending of temperature. (Ref.59043).
