Habitat and Ecology:

Habitat and Ecology

This species prefers well-vegetated muddy bottomed marginal habitats of rivers and floodplains. It migrates within rivers and moves up tributaries in shoals during the flood season (Bell-Cross and Minshull 1988). It feeds on invertebrates, especially insect larvae. Electroreception is described in detail by Kramer et al. (2007).
