Thin finger Leather Coral

I just received a large finger leather yesterday, it came attached to some rubble rock. Overnight its detached itself from the rock, is that normal? Or it just didn't like the position it was in? Should i just leave it be? Here are a couple pics.
 
Looks like a rasta... Did you have it shipped or did you buy it locally? Since it's loose I would try and rubber band it between two pieces of rubble rock and stick it in a medium flow area. Plus make sure you Alkalinity is in balance because these softies tend not do good in low Alk.
