📖 Overview

Inhabits cave, most commonly found resting on the bottom of shallow pools with flowing water. Sometimes occurs in mid-water, or also co-exists with Neolissochilus subterraneus in deeper areas with little flow. Swims along the surface of pools with its snout raised up, out of the water while moving it head from side to side. Large fish occur in the deeper zone, far from the entrance of the cave.
