I picked up this coral from the LFS a few days ago. it was actually sold to me as a toadstool but i have a feeling it more of a devil's hand coral. the first pic is right after placing. seems closed. the second is the coral starting to open the third you can see some polyps coming out to play. Now the past couple of days the coral has not been extending its polyps but has been in the "closed" then soon after "open" positions. mostly open. Not too sure if the coral is healthy or not or whether its normal behaviour. its seems to have a purple coloring to it but i have noticed a few lighter grayish spots, maybe you can see from the pic. Kinda new to the hobby so any info or input would be great. most of what i find on net tells me that they are easy to keep and medium-high flow and light. kinda vague if you ask me.
