I have a toadstool that was doing very well i haven't add anything new or changed any of my water care habits, but it closed up afew days ago and hasn't opened sence and last night i notice it was turning alittle green on top i thought it we just film so i ran my finger across it and it didn't come off.Any ideas of what is happening and what can i do.

mine did the same thing a few weeks ago it closed up one day and stayed closed and droopy for a few days it took a day or 2 for the waxy film to build up and then it started to shed and opened right back up and is doing fine now
