Penguin Tetra

Thayeria boehlkei

Family: Characidae

Ask Finn

The penguin tetra is immediately recognised by its bold black stripe that runs down the lower body and into the lower caudal lobe — and by the unique way it holds its body at a nose-up angle while swimming. This head-up posture gives schools a distinctive, elegant appearance. A hardy, peaceful fish that suits most community setups.
