Etymology: Enneacampus: Greek, ennea = nine times + Greek, kampe = curvature (Ref. 45335).
Eponymy: Dr William John Ansorge (1850–1913) was an English explorer and collector who was active in Africa in the second half of the 19th century. [...] (Ref. 128868), visit book page.

Ecology
Freshwater; brackish; demersal; pH range: 7.0 - 7.5; dH range: 10 - 18. Tropical; 24°C - 28°C (Ref. 1672)

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 13.6 cm SL male/unsexed; (Ref. 81680)
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).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00037 (0.00016 - 0.00085), b=3.18 (2.99 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
