i have a copperbanded buttery that is in a stock tank with all other corals and fish while i get my new house signed and moved into... i have seen him scavanging on the rocks and etc... he is in my shop all salinity and everything is right on no spikes of any sort or anything but i cannot find him today... he is usually very social and everything... and all fish get along... at one time he had some territory issues with my yellow tank but they dont mess with each other anymore .... any ideas why he i cant find him today...
