Etymology: Hylopanchax: Greek, hylo, hyle = material, wood + Panchax, a word created by Meinken in 1932 . More on author: Fowler.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; pH range: 5.0 - 6.0; dH range: ? - 5; non-migratory. Tropical; 20°C - 24°C (Ref. 2060)
Africa: Alima and Likouala River drainages (middle Congo River basin) in Republic of Congo (Ref. 94189). Reports of Hylopanchax stictopleuron from other parts of the central Congo basin and the upper Ivindo River (Ref. 59344) are misidentifications of other Hylopanchax species (Ref. 94189).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 3.5 cm TL male/unsexed; (Ref. 27139)
Small brooks and rivers, usually of the black water type, under forest cover (Ref. 59344). 4.5 cm max TL (Ref. 3788). Not a seasonal killifish (Ref. 27139).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.0 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (11 of 100) .
