Help IDentifying hitchhikers

[Cakebaker13]

Please help identify the following things in my tank!

1 is a cabbage-like thing growing on a very old rock I bought: http://imgur.com/pTApcpr

2 is a cluster of very tiny flowers that are popping up: http://imgur.com/a/EWZtB

Thank you!
Yes, I know there is a little bubble algae in the picture, not what I am asking about.

Those little flowers your seeing might be a patch of Clavularia or something similar. The second one looks like some type of red macro algae to me. (Fauchea?)

I think the flowers are green star polyps..?

Looks like some type of star polyp / briareum.
