Well our tank has been set up for a few weeks all parameters are good so we brought home our set of O. Clowns and one immdiatly went into the live rock and the other has been sticking too one corner of the tank been about 30 hours now. Its a 65G with 29G sump refugium the clown thats been out has ate but wont move from that side of the tank. There also very small clowns maybe 1/2 inch. Just wondering if its ok for one too be in the same spot for so long.
