Okay all... I haven't been on for a while and while I still have my 10 gallon nano, it isn't looking to good at all. When I first set it up I got more live rock for it and it had some hitchhikers on it. Some good and now that it has been a few months I have found some to be bad. There is this one Zoa/Pally looking coral that has pretty much taken over my tank and almost all my live rock has been covered by it. I didn't think anything of this at first thinking it was a nice coral but it has now started to encroach onto my zoas and some other corals and is killing them! I don't know what it is and I don't know how to get rid of it. Please if anyone can help tell me what I should do that would be great!
I only have the one picture of it when I first got the new rock and there were only a couple of them but I will try to get more picks of it later today. It is just so bad in my tank I am almost embarrassed to put any pictures of it as it is now.

Please help.
