I add Kent PhytoPlex daily then Kent Microvert once weekly. I can move it to my 75 if you think i should. It seems fine where it is and it does eat, his tenecles or whatever their called are seen going in it's mouth. I don't have any aggresive fish, unless you thing my clown surgeon will pick at it. Everything else in my 75 are no bigger than 2-3 inches, and they aren't going to get any bigger
