Am I out of my mind?

[Steve1500]

I have a 180G DT with four tangs (yellow, purple, kole and a blue hippo). The tangs have been in there for about two years. I am trading my blue niger and would like to get a powder blue and a powder brown tang. Since the other tangs are not the Acanthus species, I’m wondering what my survival success rate would be with these two additions. Would certainly put in acclimation box.
In the past the yellow has been the aggressor when I added the fish, but if I added larger tangs, at the same time, would this help?

Other options include a magnificent fox face and a copperband butterfly, but I already have a fox face.

Out of my mind?

any more than 1 foxface is a no, and copperband butterfly’s are very hard to keep

The tangs could get along, but it is always a risk

Personally I’d pick only one of the powder blue and powder brown, especially if you’re aiming to add a larger specimen.
