Biology

Forming small groups of up to 12 individuals, Bedotia geayi can usually be found in the calmer regions of its fast-flowing habitat, where the water is shaded by overhanging trees. Its diet appears to consist predominantly of insects which have fallen from the trees into the water. Bedotia geayi's reproduction is believed to be similar to that of the closely related species, Bedotia madagascariensis (2), which attaches its eggs to vegetation, leaving them to develop unguarded (3) (4). Once hatched, the juveniles usually occupy the shallows near to the riverbanks, while the adults inhabit deeper water (2).
