Africa: Ganana (=Juba) River in Somalia and (lower) Tana River in Kenya (Ref. 43912).
Length at first maturity / Size / Peso / Age
Maturity: Lm ?, range 5 - ? cm
Max length : 6.9 cm TL maschio/sesso non determinato; (Ref. 3570)
Spine dorsali (totale): 0; Raggi dorsali molli (totale): 0; Spine anali 60-75. Diagnosis: adipose fin always present; inner side of pectoral spine without serrations, being entirely smooth (Ref. 43912).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00263 - 0.01321), b=3.02 (2.83 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
