Can a Copperband Butterflyfish Live With a Porcupine Puffer?
✗ Not recommended in most tanksVerdict from our compatibility engine, assuming a typical 90-gallon reef tank. Score: 0/100.
Why
- Tank poor (90gal for 130.0gal min)
- Reef safety hard block: Not reef-safe — Porcupine Puffer will damage coral/inverts
It can work if…
- Upgrade to a larger tank — this species needs more volume
- Tank is nearing capacity — consider removing a resident before adding this one
- Reef safety concern — relocate or rehome before adding to a reef tank
