Temperament: Generally peaceful but can be territorial towards other puffers or slow-moving fish. Not recommended for small or delicate tankmates.

Reef Safe: With Caution. May nip at invertebrates and corals, so caution is advised in reef setups.
Lighting Requirements: Standard marine aquarium lighting is sufficient.
