Shriveling

Hello all, Last night i won a toadstool leather frag at the led meeting featuring Jake Adams, Which was super informative and i always love meeting at the aquarium. but back to the leather, after i acclimated it and added it to my tank it was doing very well it actually expanded and had all its (fingers, toes, polyps,) i dont know what to call them, they were all out. now today when the light came on it began to shrivel, and its loosing color around the edge.... any ideas? water param are all where they are supposed to be i just checked everything on monday and it was good.

Those small things that extend from the top surface of the Mushroom Leather are called polyps or sometimes tentacles.
I agree with Jackie, those coral can sometimes shrink in for a week.
When you say the edges are losing color this is a little concerning. Also, please give the actual numbers for Alk and Ca and what is the temperature and salinity of this tank?
Can you post a pic?

Are you coming to the WMAS meeting next month?
