Multiple tangs in a 125g

[Tek_Diver]

I have 2 Hippo, 1 Yellow, 1 Purple, 1 Sailfin, 1 Duce, 1 Valimigi, 1 Naso, 1 Sohal and a quite a few other fish in a 265. The Tangs all get along fine.

could they be fighting so much because there is only two. Should I consider getting like a yellow or something to make the numbers odd.
