In short, I got banned for arguing that you can keep many tangs in one tank without severe aggression as long as you keep them well fed. Here is the link to the thread and what I got banned for:
You got banned because you refused to listen to the advice you sought in putting five tangs in the 150 gallon you had at the time. That was excellent advice.
I see you took the advice and moved up to a 600 gallon.
Good move!
