Have one currently. No problems so far. Well, other than the gramma going on a rampage two days after I got the CB, hurting my fairy wrasse, and basically leaving his established territory and acting super aggressive for two weeks befor the CB and my female Midnight Clown both got tired of his crap and beat him into submission, with my now recovered fairy wrasse decidingto join in for some payback. Now my CB is the "sheriff" of the tank. Hence why my CB is named Wyatt Earp. And fairy wrasse is Doc Holliday, cause even while seemingly in terrible condition he still put up a fight (also he is the same color as a red huckleberry, which means he can say "I'm your huckleberry" to me, you know, if fish could talk.).
