Alestidae (African tetras)
Etymology: Brachypetersius: Greek, brachys = short + Peters, 1877, naturalist, expeditionary in Asia.
More on author: Poll.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; pelagic. Tropical
Africa: Lower Guinea endemic, restricted to the Ogowe and Como River basins in Gabon (Ref. 80290).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.0 cm SL male/unsexed; (Ref. 80290)
Anal spines: 0; Anal soft rays: 21 - 22. Diagnosis: 4.5 scales between lateral line and dorsal fin origin; 18-19 anal fin branched rays; flanks with dark lateral pigment band from opercular margin to caudal fin; humeral spot present (Ref. 80290).
Affinities: most similar to Brachypetersius huloti from the Congo River basin, from which it differs in the extension of the lateral band onto the median caudal fin rays, presence of a humeral spot and fewer scales (4.5-5.5 vs 6.5) in transverse series between lateral line and dorsal fin origin (Ref. 80290).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00528 - 0.02495), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.3 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).
