Description

The Congo tetra is a beautiful characin of the family Alestidae (African tetras) reaching about 8.5 cm. The body shines iridescent in rainbow colours - blue-green, gold and orange - and has an adipose fin, as in many characins. The male is larger and has greatly elongated, frayed dorsal, tail and anal fin rays, which it displays during courtship. The species comes from the Congo basin in Central Africa and lives in schools in clear, flowing rivers and creeks. As an omnivore it eats insects, plant matter, algae and small invertebrates. In the rainy season it spawns among the water plants. For its gorgeous colours the Congo tetra is one of the most popular African aquarium fish.
