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.

    serpae tetra

    Vital Statistics




    Origin: Amazon, Guaporé, and Paraguay River basins

    Size: 1.5 inches

    Temperament: peaceful in schools

    Sociability: schooling, six or more recommended to prevent possible nippiness

    Breeding: egglayer

    Sexing: males are slimmer and have brighter colors

    Diet: omnivorous, accepting all foods

    Water Chemistry: pH 6.0–7.8; dH 10–25

    Temperature: 72–78°F


    Serpae tetras (pronounced sur-pee) get their name from the Amazonian village of Serpa. Wild fish are brick red with a greenish sheen, but tank-raised specimens often are bred to show a deep crimson color. In any case, these highly attractive schoolers look great in a community aquarium. Keep at least six, as the species is sometimes reported to be nippy when kept in small numbers.

    Serpae tetras are easily bred. Males chase females into plant thickets, where the fish release adhesive eggs. It is common to see serpae tetras spawning in the aquarium when morning sunlight hits the tank. However, eggs and fry are readily eaten, so a separate breeding tank should be used if you want success in reproducing this species.

    Flake foods are accepted readily. Feed foods high in carotenoids, such as brine shrimp, bloodworms, and color flakes, to keep the red colors bright.
