It belongs to the family Cichlidae
Central Amazon basin, Rio Negro
General shape, similar to most other cichlids, straighter belly profile. Has large dorsal and anal fins. Grows up to 7 inches (18 cm)
Said by some, including me, to be one of the colorful fish in ones aquarium. The basic colors are gray-brown to a vibrant red-brown. There are usually seven to eight black vertical lines, with old age these lines will disappear completely. There is one lateral black line that starts on the gill covering and ends in a black patch on the middle of the body.
The female will be paler in color, while the male will be a brilliant deep blue to attract the female. On the males the dorsal fin will come to a point, while the females will be rounded.
Temperature 72-75 degrees Fahrenheit (22-24 Celsius). The ph and hardness are of medium values. A large non-planted tank with a substrate of sand or fine gravel would soot this fish well. Coconut shells and some stones will give the Jack hours of enjoyment.
Lots of live, coarse food. Some substitute for live food would be a high quality dried food.
A territorial fish once adulthood is reached, while in it’s younger years it’s a schooling fish.
Sexual maturity and reproduction:
Form strong united pairs. Will reach sexual maturity at a length of 3-4 inches (8-10cm). Open spawners.
Highly aggressive and excitable, especially during spawning periods. Best when kept in a species tank.
