umbrella mushroom help

[blue steel]

I finally got my umbrella mushrooms in and I was wandering how and what should I feed them. Also I place them on top of a rock and after a while they are on the sand bed shoud I just leave them on the sand or place them on the rocks?

Are they attached to anything?

yea it looks as if they are attached to a little peace of rock about 1/4 inch.

If it is attached to a rock then leaving it on the sand is ok. Or you could aqua epoxy or use superglue gel to attach it to a larger rock.
