Congo Tetra in nature approaches 4 1/2 inches. However farm-raised varieties, though full finned and rich with color, will generally not grow beyond 3 or 3 1/2 inches. They have long, flat bodies with large scales. This fish shows amazing rainbow luminescence along the whole body from back to front. They are generally blue on top, red and gold in the middle, and blue on the belly. Males also have long, flowing fins that are violet with white edging. The male’s tail fin is long and flowing along the vertical medial line.
These African characin fish are found in the upper reaches of the River Congo in Zaire. They populate streams, tributaries, pools, and marshes, preferring murky, slightly acidic water. The 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.
