I bought 5 blue mushroom corals and wanted to have them stuck to a piece of live rock in my tank. To do this i tried letting them adhere to some gravel and then i was going to superglue them onto the rock. This failed.
Next i tried to get the mushrooms to adhere to the rock naturally. To do this i used a portion of nylon mesh. I got it from a used orange bag. I took the rock out of the water, placed the mushrooms on it and put the whole thing in the nylon mesh. I secured the mesh under the rock and placed it back in the tank.
I left the mesh on for about a week. After taking it off the mushrooms were nicely attached to the live rock. Sweet.
