Wervels: 35 - 36. This species differs from M. aureum by having the last abdominal spine reaching the anal-fin origin or almost so (vs. last abdominal spine clearly separated from the anal-fin origin), vertebrae 35-36 (vs. 38-39), and a conspicuous black blotch on opercle (vs. no black blotch or inconspicuous); differs from M. albiscopum by anal-fin with branched rays 26-32 (vs. 31-38); differs from M. unimaculatum by having circumpeduncular scales 30-34 (vs. 34-40), perforated scales on lateral line 74-98 (vs. 95-110) and vertebrae 35-36 (vs. 37) (Ref. 117280).

Reported to be an herbivore fish, which is highly dependent from the floodplains and of great economic importance for both commercial and sport fisheries (Ref. 117280).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02512 (0.01329 - 0.04746), b=3.03 (2.86 - 3.20), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisch niveau (Ref. 69278): 2.8 ±0.36 se; based on food items.

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).

Prijsklasse (Ref. 80766): Unknown.
