New Deco Live Rock

[rrbigdog]

Newbie with limited knowledge.

First Pic can someone tell me what a few of the things on the rock are:

Long finger looking thing thats orange and in middle of picture..
The other item lower and to the right. Color not showing very good but it is green and white
Then I have a few rocks that have the white thing that is at 3 o'clock on the rock.

Second picture - Base of the horn looking thing.

Mushrooms, the long finger thing looks like it could be a Finger Leather of some kind. It also looks like Star Polyps on the rock and under the Finger it looks like a Hammer Coral and I see some skeletons there that could either be Candy Canes or possibly Sun Polyps.

I took a few more pictures to help. And I found something new. I think you are going to tell me its not good.

Is first pic a bad anemone? Seems to have moved from a hole in the rock to a small ledge.

Second Pic - ID Confirm. I have been target feeding mysis shrimp to this. Is that the right thing to do? Seems to look better and opens at night.

Third Picture - This looks like some skeleton but I have noticed feelers glowing under blue LED. Will this continue to grow? Target feed it mysis?

Any help thanks.
