Environment: milieu / climate zone / depth range / distribution range
Ecologia
; acqua dolce demersale; pH range: 6.8 - 7.8; dH range: ? - 25. Tropical; 22°C - 28°C (Ref. 13614); 35°N - 5°N
Africa: Nile and Chad basins (Ref. 3202, 57223). Report from the upper Benue (Niger basin) (Ref. 57223) needs confirmation.
Size / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 3.1 cm TL maschio/sesso non determinato; (Ref. 57223)
Spine dorsali (totale) : 1; Spine anali: 0. Diagnosis: body short and robust, its depth 4.2-5.2 times in standard length; head as long as broad, dorsal surface rough; maxillary barbels non-membranous and unbranched, up to 2 times longer than head; mandibular barbels with short, simple ramifications; humeral process long and pointed; 1st dorsal-fin spine smooth on anterior and posterior margins; 2nd dorsal fin with 10-14 rays; pectoral-fin spines more strongly denticulate on inner than on outer margin; caudal fin deeply forked, with upper lobe slightly longer than lower (Ref. 57223).
Coloration: general colour pattern similar to that of M. niloticus, but there seem to be fewer dots on dorsal fins (Ref. 57223).

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=0.00933 (0.00303 - 0.02871), b=3.05 (2.80 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±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).
