They are all in the same set up with a ton of live rock the juvenile was in the tank first for about a year. Then I introduced the adult and flag fin 2 months ago and at first there was a little aggresion but it only lasted a day or two and all has been well ever since. I also have 3 blue Hippo's and a Tennent, orange shouldertang and purple tang living in perfect harmony. If u can do the same thing in your set up that would be awsome geuss U just have to try if it doesn't work out u can always put it in your QT and sell it .
