Otocinclus Catfish
Otocinclus catfish are commonly found in slow-flowing shallow rivers and streams in South America.
In their wild habitat, the fish attach themselves to rocks, driftwood, and other stable surfaces to feed off algae. The waters in this habitat are moderately-vegetated, with good access to sunlight and a soft, sandy riverbed.
