Fragging ToadStool

I have a toadstool Leather I purchased today and want to cut it off and glue it to a larger rock. Can I glue this like I do many other frag's? The tank is in the office so I would like to do this before 5 if possible. Thank you very much for your time.
I will do an introduction in the appropriate forum after I get off of work this evening.

Toadstoal will slim up if you try to glue, cut it off and put a tooth pick thru the stalk, take a rubber band and fasten it from the tooth pick around the rock and it will attack on its own in a matter of weeks

 

Knowing that I might just bring my Dremel Tool and try to cut the rock down to a sliver. My intention's are to glue it half way down the back glass of my aquarium. As it grow's do you think it will attach itself to the glass?
Or must it be another rock for it to attach itself to?

+ 1 on toothpick and rubber bands....wont stick to glass...leave the dremel for LPS

 

It will eventually attach to anything near it
