Can a Copperband Butterflyfish Live With a Purple Tang?

~ Possible with caution

Verdict from our compatibility engine, assuming a typical 90-gallon reef tank. Score: 52/100.

Why

  • Tank poor (90gal for 130.0gal min)
  • Tank heavily stocked (211%) — over recommended load

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
