📖 Overview

Adults occur in coastal rivers and streams , and swamps . Seems confined to fresh water habitats and breeds in fresh water . Ovoviviparous . Feeds (mainly) on copepods . Male carries the eggs in a brood pouch which is found under the tail . Dawson (1981) reported 17-36 postlarvae in the brood pouch of males of 75.5-82.5 mm SL; a larger male (MRAC 143259: 136.4 mm SL) caught in December 1964, in a swampy area about 200 m from the coast of Bioko Island (formerly Fernando Poo), has its brood pouch filled with several hundred postlarvae .
