thanks for all of the fast replys.... I curently only have a 75g FOWLR. I have about 120lbs of lr, choc chip star, Condy Anemone, Percula Clownfish, Pshodochromis, and a green chromis. Do I need a cleaner shrimp or can it hold off? I know that it is really nice to have them with Tangs and I do want to get (soon) a Regal Tang (lfs gets one in a week and is sold by the time I get there) and a Hawiian Yellow Tang.
