Heres my 5 inch Humma from my 110FOWLR . Greatest personality in the world. Spits sand all over and knows every inch of HIS tank. So far very compatable with my Purple Tang and inverts.
I actually have 2 cleaner shrimp in the tank and both have been on the clown at the same time cleaning. They have all lived together for well over 6 months one cleaner was in there before the clown one added later with no problems. I have even seen them cleaning inside his mouth.
