Penguin Tetras

Penguin tetras are fun schooling fish to keep. They are active fish that get along peacefully with other penguin tetras and other species that are calm and similar in size.

With the signature black band that runs across their whole body and their unique half-upright swimming style, they are entertaining. Penguin tetras are most known for being fin nippers. Don’t let that trait put you off them, though. The truth is that their nipping is nonexistent or greatly reduced when you keep them in a group.
