My toadstool slumped and retract it's polyps. I've had this leather for 6 month now and then 3 month ago I relocated it here in the 10 gallon. It had doing well since I moved it here, it's getting good amount of flow and light, no problem at all. Then suddenly this happen. It has been like this for a week now, I've did 20% water change twice and it doesn't change anything. The other corals look happy with full polyp extension.
I little worried cause it has never been like this. A few week before I saw it shedding for 2 days and the polyps stretch out again, but it doesn't slumped when it was shedding
What should I do?
