Biologie     Verklarende woordenlijst (b.v. epibenthic)

Common in the lower reaches of rivers and streams, and in estuarine habitats. Ovoviviparous (Ref. 205, 44894). Occurs in mangrove estuaries and tidal creeks (Ref. 44894). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Male matures at 7.5-8.0 cm SL.

Life cycle and mating behavior Geslachtsrijpheid | Voortplanting | Kuitschieten | Eieren | Fecundity | Larven

Female deposits eggs on the ventral surface of the male's trunk or tail, where they are incubated for several weeks (Ref. 2847).
