Description: While African red-eyed characin is requires a larger tank, this is one of the finest of African characins and a species everyone should try at least once. They are characterized by two lateral bands, the upper one red or orange, and the lower blue-green. The upper half of eye is red, giving this species one of their common names. The Niger tetra has huge scales. The anal fin is convex with red, yellow and black stripes on male, and nearly straight with a black point on female. For breeding use soft, slightly acid water.

One pair has laid more than one thousand eggs in a sigle small tank. Those fry hatched after 30 to 35 hours, surfaced on the fifth day and were swimming by the seventh. The fry are especially timid and when frightened flee head-first to the tank bottom - so this should be soft, of peat or very fine sand. The fry grow rapidly and are nearly 2 inches long within seven weeks. They should be first fed finely ground food then, from the second week, brine shrimp, finely ground flake, egg-yolk, Liquifry and Cyclops - all foods easily obtained.
