Tang housing advice

[iceman86]

In my 8' tank I have a naso, yellow, sail fin, orange shoulder, liutenant, and clown tang. They are all 4-6" and all get along. I have a 3" Niger trigger in there as well and he's actually the bully.

I wanted to add a purple tang during the transfer from the 75g to the 150g. However I already have a powder brown, yellow and regal tang. Lots of information on this thread.

i guess is best to add them at the same time?
