Tang attacked Goby!!!!

[gefilte]

I just got home and found that my gold headed goby was't looking too good. He looked a little tattered and was swimming (if you can call it that) like he was drunk. Then I saw my yellow tang attack him. He's totally terrorizing him and its not looking too good. I don't have a qt, but I put the goby in a cup inside the tank so the tang can't get to him. Is there anything I can do?

Watch for signs of infection and remove to a qt if necessary. I would definitely start getting the stuff together for one. You may not need it now, but more than likely will need it at some point in the future. It is also a good idea to qt all new fish.
