Can a Royal Gramma Live With a Spotted Sweetlips?

✗ Not recommended in most tanks

Verdict from our compatibility engine, assuming a typical 90-gallon reef tank. Score: 0/100.

Why

  • Tank overstocked (572%)
  • Size capacity hard block: Tank far too small (90gal vs 500gal min for Spotted Sweetlips)

It can work if…

  • Tank is nearing capacity — consider removing a resident before adding this one
  • Upgrade to a larger tank — this species needs more volume
