They don't ship well, and the LFS should have kept it longer than 24hrs to allow it to recover from the stress of shipment. at this point all you can do is minimize its stress by ensuring that it's placed under enough light, has a piece of LR to attach its foot to, and that nothing in the tank is disturbing it. Don't move it anymore than you have to, but it should not be directly on the sand. Realize though that once it attaches lo the LR you will never be able to move it, so we usually attach them to a small piece of rubble. Also, as stated, they need stable water conditions and they eat phyto so you should plan on starting to dose the tank with phyto.
