so i went to look at my tank about 10 minutes ago and i can not find one of my ocellaris clowns i have 2 and 1 is quite a bit bigger then the other, The one that is missing is the small one and i cant find him anywhere. Ive checked the overflow box i took the drain line off that goes down to the sump and he is not in the hose checked my sump and refugium and hesw not there either. He has never done this before he is always with the otoher clown could he be hiding?
