Did I get anemone hitchhikers? Newb here

[pollywog]

I have a ton of freshwater experience, but absolutely no reef experience, other than the past month of cycling my 37G. Now that all the levels are nil, I put a couple of zoa colonies from my lfs in the tank to get me going about a week ago. I got a bunch of hitchhikers, 3 brittle stars, some shrimp looking things, a ton of different worms, and some little bugs that crawl inbetween the zoas.

While the zoas have mostly stayed closed since they've been in the tank, there were two that always seemed to be open, and active at that. When open, they look very similar to the other zoas, but they seemed different. Their base/foot wasnt like the other zoas, and they were rooted in little tunnels in the rock.

This morning I noticed one in the middle of the tank, attached to what appears to be a dead shrimp. It finally hit me - those two things I thought were just mutant zoas might be anemones, or perhaps a different type of coral. There are two other things on the rock that I cannot identify. Let me know what you think! If they are, I got some research to do.
