It was fine two days ago, then I noticed the big ugly worm thing (that I hate) near it last night.
Today, I came home from work and it looked like this:
The whole thing is completely retracted, more that I've ever seen it- even when I've moved it. Then there's a cloudy slime on the top half, and it looks like the tentacles underneath are gone. The bottom half is retracted and looks like it's probably not going to make it.
Checked all water levels. They're good. All the other corals are good.
What happened?
