Carpet anenome

[Chase31]

So after much hmmmming and hawing and the lfs having a really nice healthy nem for 2 months or so now I made the purchase. I had a LTA before and my clowns didn't host it and wasn't really the look or color I want for my tank. So as my levels have been saying nice for the past two months and everything's starting to go well. I would like to know forsure what species it is, following are some pics, it's only been in the tank for 4-5 hours. Do the carpets generally like the sand or rock? It moved it self off the sand onto this rock and it's mouth is open. What do you guys think.
