Hi, I have a sick brain coral that is confusing the heck out of me. I was out of town for two weeks and during that time the brain coral shrunk back to it's hard skeleton. Now, there is still color but holes are starting to develop in the skin. The odd part is the brain expands at night and looks like it is getting better. Then, during the day the skin shrinks and pulls tight. This is when the holes are evident and appear to be getting worse. Anyone have any ideas? I'm thinking of putting it in the dark for a while, but I don't know if soft brains can handle long periods of dark.
