welcome to the wonderfull world of zoanthids, one colony melts while its neighbors grows like crazy. a little tip if your gonna keep zoanthids is expect loss no matter what you do, each and every one reacts different to an aquarium and what does good in mine might die in yours and vice versa. yuou can try to move the frag somewhere else to see if its lights or flow bothering it, could be a fish nipping at it, amonia,could be sand,bristle worms,algae the list is literally endless. they are not a beginner coral regardless of what people say so spend small amounts on frags and trial and error untill you know which ones grow and do for you and which ones eventually melt away

I found with a few colonies that when they do this take out a turkey baster and blast them to clean everything away. That sometimes works. Then look for the little worms that can sometimes popup around them. They look like little tubes and I see them come out at night and sting the zoas. Break those off if they are close by. Good idea to take a look at them during the night and see what is going on. Too much light is definitely another killer and it wont kill them right away might take a week or more before they start to close up.
