It's been 3 days so far and the skeleton line doens't seem to be getting any worse. I was a little afraid yesterday because each of the mouths were opened to about the size of a dime. Next time I looked, they were back to closed.
One question I had was; when I got the coral he was attached to a small piece of rock, the rock actually fit like a puzzle piece into my own live rock, so I didn't bother removing him, but just added the new rock to my own.
After doing a little more poking around, I came across a couple of websites that said open brain corals prefer soft substrate. Do I need to position him in the sand bed instead of on the rock? I'm getting conflicting advice and would like some clarification.
Also, the lady at the store said that the coral was about to split. I haven't found any information on brain coral reproduction. Do brain corals actually divide?
