I was considering adding one to my tank. I have 110 gallon high with live rock. The tank contains about 50 hermit crabs, 2 emerald crabs, a cleaner shrimp, a scalet shrimp, 2 sea serpants, a yellow tang, purple tile fish, flame angel, coral beauty angel, two maroon clowns, and an orcid dotty back. My conserns are will it be to slow to feed in my tank and will he one day eat my dotty back? Any help greatly aprieciated
