The back polyps on this frag have been partially closed up like this for several days now. The front polyps are happy as can be, but I don't understand why these guys might be so unhappy? Water conditions are good. There was a little time where a lot of activity was happening near there. I added a ywg/pistol and they made a burrow fairly close by. For a bit they were scared of the clown so I had to spot feed sinking pellets to them and that naturally attracted some cuc but honestly I haven't seen anyone climbing on it. Any thoughts as to why they might be sad?
