✗ Not recommended in most tanks

Why

  • Species conflict: Known conflict: Arothron puffers eat crustaceans and urchins — not safe with inverts
  • Reef safety hard block: Not reef-safe — Immaculatus Puffer will damage coral/inverts

It can work if…

  • Known incompatibility — these species are documented to conflict
  • Reef safety concern — relocate or rehome before adding to a reef tank
