Great pictures Alex!
For the toadstool, slice off a section of the crown, a small section is fine. You can then rubberband that piece to a rock. I've done it this way with success before.
Keep the pictures coming!

Here is the last baby for awhile. She was born about 11 oclock this morning and was about an hour old in these pictures. A friendly little filly! :mrgreen:
Now I'll stop with the pony pictures...... :cool1:
What were the params when you tested last? How do the other corals look? It sounds like the bulbs might need to be replaced.
Also, if you haven't had these zoas long, they could just be adapting to your lighting.
I agree with Tim, a leak isn't anything to mess around with. There is alot of confined pressure inside a tank, and at any point it can give if there is a weak spot.
