Was I lied to?

I went to the LFS that I really like in centerville yesterday. I came home with a clarki and a waving hand coral. The little Clarki took to my tank like a champ. He and the Percula are jiving <---that's actually a word, like I hoped they would in a larger tank. But the waving hand is having some trouble extending some of it's appendages. More than half are out and so far seem to love the flow of the tank. It's the side that's away from the majority of the flow that isn't extended. Also, the LFS told me that it was an easy coral to take care of. However, when I got home and started researching while it was acclimating, I found out that it's a very difficult little bugger. Can anyone give me a leg up on how to care for this guy? I can throw up some pictures if it would help. Thanks everyone.

 

Do you have waving hand anthelia or do you have waving hand clove polyps?

 

Maybe a pic to get the correct ID would help

Thanks
