Reintroducing a Trigger

[Joe Reefer]

When I added a pair of blue throat triggers recently, the existing niger decided it would chase the female blue chin around. So I promptly fished the niger out and placed him in the prop tank for temporary holding until I could find him a new home.

Now my question is what are the chances of everything being ok if I were to put the niger back in? The tank has been re-aqauscaped since its removal. He generally was very calm to other fish that have been added. In fact he is living with a little baby clownfish in the prop tank. Should triggers just not be mixed? I am not exactly sure on the mixing rules of triggers? Any thoughts are appreciated.
