Hi all, I have this Acan coral that I can't for the life of me get to open. I've checked all the parameters and nothing jumps out at me as the reason why it stays closed. I've also tried various locations and combinations of lighting and flow. Anyway, I'm not expecting a magic answer on how to make it open, but today I looked at it and though the polyp was closed, it's mouth was wide open. And I mean WIDE. Wider than I've ever seen a coral open it's mouth. It seemed to be expelling a trail of brown slime, which I've seen many of mycorals do, but never with the mouth this wide open. I attached a picture of it. Is this normal? Might this gaping hole hold a clue as to why it won't open? Thanks in advance.
