Central Africa, in the Zaire river basin.
General Body Form:
Long and stretched out, with large eyes and scales. In the males the
middle rays of the Caudal fin are long and the Dorsal fin is also very
pronounced, reaching all the way back to the start of the tail (caudal)
fin. The females are smaller and their fins are not as elongated as
The colors on this fish vary from individual to individual and can show
the complete spectrum of iridescent colors. The sides are marked by
a light Brown stripe and under this are stripes that vary in color from
a shining Gold to Green. The fins themselves also vary in color ranging
from a pale red to Gray. The tail and Anal fins are edged in white,
with the Anal having a Black blotch in the middle. The base color of
the fish is Olive in color, and the underside has a Purple to Violet

The fish we see today pales in comparison to the original wild caught
specimens, the finnage is shorter and the colors less pronounced. They
are best kept in schools of at least six with other non aggressive fish.
A fairly large tank is best, arranged with dark colors and substrate.
Provide plenty of open areas for swimming, loosely planted along the
sides and back. Good water circulation is a must. The Congos are Insectivorous,
but will accept flake and frozen food as well. To bring out their best
colors, you should supplement their food with live Daphnia, mosquito
larvae and brine shrimp when available. They will thrive in slightly
acidic, soft water with an average temperature around 77 F. water changes
are a must as they are sensitive to water quality.
The Zaire River watershed.
A large breeding tank is needed, with acidic very soft water. A peaty
substrate is best. After an energetic courting the female will scatter
about 300 pale Brown eggs among the bottom plants. This is usually done
early in the morning when the first rays on the sun hit the tank. The
eggs will hatch in six days and they must be fed at once with brine
shrimp nauplii, rotifers or finely crushed flake food.
