its about 4 months old haha and yes at first i was just holding it in my tank for a week or so for a friend of mine but ive kept him in there for almost a month or so. the grouper is almost as small as the clown and they dont bother eachother. i also had a little snapper in there as well but hes going with the grouper back to my friend soon especially if you think thats the problem. other than thank thers about 10 to 17 pounds of live rock. my water was all god about a month ago a local pet store tested it and said it was fine. do you think i should get rid of the grouper and the snapper?
