Opmerkingen | Common at altitudes of 300-1000 m, especially in clear streams of the sandstone belt. Prefers pools, where it is frequently the only fish species present apart from eels. It thus represents an important link in the food chain, feeding on aquatic insects and other small invertebrates and falling prey to eels, birds and others (Ref. 7248). Feeds on insects and frogs (Ref. 12501). |
