Can a Threebanded Butterflyfish Live With a White Faced Butterflyfish?
✗ Not recommended in most tanksVerdict from our compatibility engine, assuming a typical 90-gallon reef tank. Score: 0/100.
Why
- Known conflict: Same-genus butterflyfish (Chaetodon) quarrel unless introduced as a known pair
- Reef safety hard block: Not reef-safe — White Faced Butterflyfish will damage coral/inverts
It can work if…
- Known incompatibility — these species are documented to conflict
- Upgrade to a larger tank — this species needs more volume
- Reef safety concern — relocate or rehome before adding to a reef tank
