Size / Gewicht / Alter
Geschlechtsreife: Lm ? range ? - ? cm
Max length : 13.6 cm SL Männchen/unbestimmt; (Ref. 81680)
Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 22 - 29; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 2 - 3. Diagnosis: 11-15 (median 13) pectoral fin rays; head length 8.4-10.8 (mean 9.4) times in SL (Ref. 57226, 81680). Snout tubular, relatively short (Ref. 57226), ratio head length/snouth length 2.0-2.8 (mean 2.5)(Ref. 57226, 81680).
Body shape (shape guide): eel-like.
Adults occur in coastal rivers and streams (Ref. 4127, 81680), and swamps (Ref. 57226, 81680). Seems confined to fresh water habitats and breeds in fresh water (Ref. 81680). Ovoviviparous (Ref. 205). Feeds (mainly) on copepods (Ref. 81680). Male carries the eggs in a brood pouch which is found under the tail (Ref. 205). 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 (Ref. 81680).
