Purple tang is getting wrecked by my yellow tang...

[Mr Cob]

75 gallon regular tank with an Established Yellow tang.

Just added the Purple about two hours ago and he is getting worked by the Yellow. Yellow will not let him anywhere near the "reef" or rock work...

Purple's fins are getting torn. Both fish are the same size.

Should I wait it out?
Remove the Purple and put him in the sump?
Yellow is not coming out...he's smart, I already tried.

do you have any eggcrate to use as a divider to separate them out for a while?

I've had this happen before. What I did was turn off the tank lights and cover the tank with a sheet. I forced them to sit in total darkness for 24 hours. When the lights come back on they don't seem to be as aggressive. Just the occasional skirmish.

just let them be ... ours fought real bad for the first 3 days than after about a week they got along real well .... i just added a mimic tang (SP) and they let it in like it was there child lol

LOL that sounds like a good deal

It's funny, the purple has been forced to the upper left corner of the tank but he is starting to defend it now...so I'm hopeful.

I like the idea of turning the lights out and may do that if he loses his footing on the corner.

It's been exciting to watch these dudes.

Julian... I'll give you the shreds from his tail. LOL!

Okay, using Jacob's idea... lights out... the Yellow is getting too crazy.

The egg crate dividing the tank worked great for us. We added our purple into our 100g maybe three months after the yellow tang, who was very sure he was boss of the tank by then. They scrapped pretty badly. Had to move a couple of pieces of rock in order to get the egg crate in there, then left it for a week. When we finally pulled it out, there was peace on earth.

Funny enough, we could not wedge the egg crate perfectly no matter how hard we tried, there was always a tiny gap somewhere. Every other fish in that tank found its way between the two sides, but the tangs could not, so they were the only ones really on restriction.

I did the same thing when I introduced a Naso, my Powder Blue was really going at him. So I turned the lights out a few hours and the next day the Powder Blue wasn't as aggressive. I also put extra Nori in the tank because I read somewhere that if they're well fed they tend to be less aggressive as well. Worked so far. Good Luck!

One thing I've read about a number of places is that rearranging some of the rockwork when adding new fish helps decrease aggression because you essentially give the established fish a new territory to scout out rather dumping a new fish in when the old fish has an territory to defend.
