So I have had this hammer coral for about a little less than two months, I had to rearrange my tank because I had to install a overflow for my sump about a week after that my hammer started not opening all the way and it looks like his polyps might be shrinking, I have already lost another hammer coral so I cannot loose this one I don’t understand what’s wrong with it it is not in direct flow and no matter where I move it to in my tank I stays almost closed
