The Penguin Tetra's prominent black line and unusual swimming/resting motions can be quite eye-catching, and give the fish a strong sense of individuality amongst similar sized tank mates. Good water quality is preferred as these fish can be sensitive to nitrates. Otherwise they are relatively easy to care for and make a good addition to a community aquarium of similar sized fishes. Known to be nippy with long finned fish. Keep in groups.
