First post on here, hoping to get some help on IDing if this is something serious or a coral doing weird things. I have had this leptastrea for a few months now and it does this weird thing where it puffs up like this. Any idea what it could be? Overall seems healthy and has polyp extension but I am trying to determine if it is too much light, a disease, a leptastrea thing? No clue, any help is appreciated.
