Toadstool Leather seems to loose from rock

[MAXreefer]

Hi all,
I got a nice double Toadstool Leather Coral from my LFS couple weeks ago. He was attached to a smaller piece of rock which I glued to a big LR in my tank.
He seems to me doing very well. Since yesterday the biggest stem is not standing upright anymore and starts to lie a little flat.
Had a look at the piece of rock he was attached to and it seems he became loose and just a small part of the stem is still attached.
Is this a bad sign? What can I do to get him attached again?

Thanks for any help or suggestions
Michael

Can you post a pic and your water params? Usually a rubberband is enough to secure it to the rock while it attaches itself. Mine took about a week to attach.
