Penguin Tetra (Thayeria boehlkei)

Penguin Tetra Tropical Fish Learn all about the Penguin Tetra's feeding habits and food types, its behaviour, its origins, its natural habitats, is it male or female, breeding advice and information, suitable tank mates, its sizing and growth range, minimum tank size, water PH and more. Use our fish community creator tool to plan your tank set up and ensure that the Penguin Tetra is the right fish for your aquarium.

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.
