Hey everyone, recently I have been having trouble with my Acan frag. The coral is closed up tight and actually receding flesh, as well as the center mouth is wide open. What I think is the problem is that the temperature is fluxuating too much during the day because its so hot. The tank normally sits at 79-80 degrees and has been reaching up to 83 degrees at some points throughout the day. Other coral like my Trumpet frag rock has lightened up in color
