Acclimation box and wrasse question

[spiraling]

Hey all,
So the newcomer has been in the box two days and I plan to let him out this evening (three days, two nights in box)
Both have been displaying quite a bit. I haven't seen anyone charging the box, but all fish are curious at times.

So how do I know its OK to let him out? Is it just that 3 days is usually enough to decide their social roles or am I looking for other clues?

Success!
I opened the box and everything has gone well. No major signs of aggression from any fish that I could tell. As the two wrasses were swimming together they were flashing a bit, which it the first time I've seen the Mccoskers do it.
