The Congo tetra has a typical full-bodied tetra shape with rather large scales. When mature, the iridescent colours of the Congo tetra run through the fish from front to back, starting with blue on top changing to red through the middle, to yellow-gold, and back to blue just above the belly. It is not its fluorescent colours that make this tetra so distinct, but rather its tail fin, which develops into a most beautiful grey-violet feathery appendage with white edges.
