Hi All!
Aftre 3 weeks of successful quarantine, I finally introduced my little yellow tang into my 65g reef tank. The moment I did that, my foxface fish (thats been in the tank since xmas) went ape**** on it, trying to bite it, push it, and chase it around the tank. I had forgotten to kill the lights in the tank when I introduced the tang, so could that be the problem? Did I just shock the foxface? I have read nothing about foxfaces being aggressive except to other foxfaces. They are both yellow in color, but would that really be why one is attacking the other? My foxface has not done that to the other 7 inhabitants in the tank and he is usually a real pansy. You walk up to the tank and he hides, stick your hand in and he hides, new fish, he hides, etc....
I have put a net barrier up today splitting the tank in half. They can see each other but the fox hasn't tried to go after it or break through the netting.
Shoudl I leave the net in place for a week or 2 so they get used to each other

Or was it just that I didnt have the lights off? I love both fish and wouldnt want to have to get rid of either one (but would of course) if they were not compatible.
The tank has lots (probaby 70-80 lbs of liverock, and corals, as well as lots of hiding places.
Any advice, etc? I love both fish and want to keep them both, if possible...
