Tetra Congo

These African Characins are found in the upper reaches of the River Congo in Zaire. They populate streams, tributaries, pools, and marshes, preferring murky, slightly acidic water. Congo Tetra generally congregates in areas with tall vegetation, few trees, and substrates made up of sand, silt, and mud. Swimming in large schools, the Tetra feed on worms, crustaceans, insects, plant matter, and algae.
