The Northwest Arkansas Aquarium Society is an organization formed to bring together the aquarist community in Northwest Arkansas and the Ozark region. Our members range from new hobbyists to long time breeders, and we keep a large variety of fishes.

Come to a meeting! Learn about fish and make friends with fellow hobbyists.

    Triangle Cichlid

    Vital Statistics




    Origin: Amazon and Rio Negro basins, Brazil, Guyana

    Size: 10 inches total length

    Temperament: usually peaceful

    Sociability: schooler, except when spawning

    Breeding: egg depositor; exhibits parental care

    Sexing: difficult; males have smaller, pointer breeding tube

    Diet: omnivorous, but highly herbivorous; accepts flakes

    Water Chemistry: pH 5.0–7.0; dH 5–12

    Temperature: 79–82°F


    Above: adult triangle cichlids

    The uaru (prounounced "waroo") or triangle cichlid is a gentle and delicate fish. Though omnivores, they are highly herbivorous and will decimate aquatic plants. Supplement the diet with plenty of fresh greenery. Triangle cichlids will make short work of romaine lettuce and spinach leaves. Algae tablets and other vegetable-based foods should be offered along with other traditional aquarium foods. Flakes are readily accepted.

    Juveniles look nothing like their parents. They have a tan to dark body, whose color varies with mood. Against that background is a starfield of small, light spots. These disappear with age, to be replaced by a large, dark triangle.

    Triangle cichlids are difficult to breed. Like discus (Symphysodon spp.), the fry feed off the body slime of the parents at first.
