CONGO TETRA

Congo tetras are fairly hardy, but only if kept in habitats that are maintained correctly. They prefer still, dark, soft, peat-filtered water with low light levels. This can be achieved with dim aquarium lights and floating plants. They like darker substrates and enjoy nibbling on bottom-growing plants.

To help your fish maintain good health, you'll need to provide them with plenty of space and carefully filtered water. If the quality of the water drops, Congo tetras may lose some of their colorations or wind up with damaged fins.

The males get up to 3.0 inches (8.5 cm). Females up to 2.75 inches (6 cm). The male is larger with more color, also the tail fin and dorsal fin are more extended. They also have different colors and extensions in the caudal fin.
