Body covered with very big scales; dorsal and anal fins almost fused with the caudal fin; 2 barbels at the extremity of the lower jaw; adult silvery, juvenile with blue glints and a yellow-orange bar (Ref. 12225).

Biologie     Verklarende woordenlijst (bv. epibenthic)

Is an omnivore with a tendency to feed on fish at the surface. The superior position of the mouth allows it to capture its prey while swimming from below. Also jumps out of the water to feed on large insects (Coleoptera; Ref. 27548). It is capable of adapting to environments with low oxygen levels (Ref. 12225).

Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven

The male carries eggs, larvae and early juveniles (alevinos) in his mouth (Ref. 1672), which lasts for nearly six weeks (Ref. 102836).
