Hello all hope all is well and safe for everyone. So my acans have started to look very sad over the last week. I have the 2 of them in a 20 long tank with multiple other corals. The acans are the only ones looking sad and everything else is happy and growing. They closed up about a week and a half ago and it started with only one of them first and the the other followed a day and a half later. I have witnessed them at night and their feeder tentacles do come out. All of the research I have done leads to "sometimes scans do this and give it a week and they should open back up" but it's odd that they both are doing this at the same time. Any input is welcome and God bless!!
