A 120 gallon or larger, fish-only, carnivorous aquarium is suitable. The Arothron Dog Face Puffer makes a great addition to these tanks with its great personality and unusual appearance. It will eat invertebrates found in a reef tank. It tolerates other Puffers that are not more aggressive than itself. It is shy at first, and becomes alarmed when in a net, therefore, use a container to transfer it.
