First Post! Help I.D. Live rock Hitchhiker Please!

[tyveck]

Hey fellow reefers! I have been reading tons of post on here for the past 6 months. This is my first post! I just setup my first Saltwater aquarium on Christmas! I am very excited! I have had some live rock I purchased from a friend and it has started growing some pretty cool stuff on it already:> I would like an ID on a few of the cool things that have been growing:>
Here they are!

looks like an aiptasia

Thanks! I am still not sure about the other though

The first two pictures are of a Ball-Tipped anemone.

First ones are ok, ball anem, the second is an aptasia = bad. I would get some joes juice or use kalk paste to kill it before they spread

Agreed with the IDs of ball anemone and aiptasia.

I got rid of aiptasia by adding a peppermint shrimp. People say they are a hit or miss, mine was a total hit

My peppermint shrimp made quick work of all the nasties
