Hammer coral question

[hammy]

I have a hammer coral frag that was trying to attach to a bigger rock. It has came off the rock that I bought it on. I was wondering if anyone knows a good way to get them to reattach. Can I use a rubber band or what is the best method to get them to attach to a rock?

branching ones wont attach, you have to use superglue
if its a wall hammer, i dont know.
i had to superglue mine/stick them in holes in the liverock
