Mushroom Coral (loose. (how to attach?)

I have a couple of loose mushrooms that keep floating around . I have to find them then put them back and hold them in place with some loose shells but they never seem to attach.
How do I attach them where i would want them?

 

There are a lot of ways but the one I find best is to use a mesh material (even a fish net) and cut a small swatch out. Then place the mushroom were you want it and wrap the mesh around it. Secure the mesh with a rubber band and let it be for 5 or 6 days. Then remove, it should be attached by then

what about super glue? I don't remember exaclty, but I think that mushrooms don't really like that? Maybe that was for Xenia ...

 

Most soft corals produce a slime when disturbed that makes it impossible to glue them onto rock.

 

thanks guys
