i got a small yellow tang about a month ago now hes a med. my lawnmower blenny's fins dont touch the rock when he perchs or more accurately weebles on top of the rock and corals. Probably more than 3/4 of my hair problem is gone and it doesnt seem to be coming back or growing where it already is now that i hooked up a fuge and run phosguard every other week for a coupla days.
