Bubble Coral

[donna2933]

I have a bubble coral that was doing great and expanding and I would occassionally feed it silver sides, however, the last couple of days it has started going inside the rock and you can hardly see any of it. I cannot find anything wrong with water conditions and nothing has changed in the tank. I can't understand why all of a sudden it isn't looking good.
Thanks

Mine does that occasionally and when it finally comes back it's bigger than before...

Thanks for the information. It is looking better now, just never had done this before since I've had it.
