脊椎骨: 37. This species is distinguished from M. aureum by having the last abdominal spine reaching the anal-fin origin or almost (vs. last abdominal spine clearly separated from anal-fin origin), vertebrae 37 (vs. 38-39), and a conspicuous black blotch on opercle (vs. black blotch absent or inconspicuous); differs from M. albiscopum by the anal-fin branched rays 28-32 (vs. 31-38), circumpeduncular scales 34-40 (vs. 28 to 36), pored lateral line scales 95-110 (vs. 74-99); differs from <>M. duriventre by the circumpeduncular scales 34-40 (vs. 30-34), pored lateral line scales 95-110 (vs. 74-97), and vertebrae 37 (vs. 35-36) (Ref. 117280).
Reported to inhabit rivers margins and lagoons, feeding primarily on leafs, fruits, seeds and invertebrates, and total spawning during the flood season (Ref. 117280)..
