I have a trio of bartletts...... One male two females. I wouldn't say the male is overly aggressive but kind of just keeps the females in check once in a while. As long as they are well fed you will not see an exaggerated amount of aggression.

This is the comment I see most, and the reason I don't keep them, and too bad, I agree, they are so pretty.On 3 different occassions I have purchased groups of 10-12 Bartlett's and i have ended up with 1 each time (it is never the best looking one of the group either).
They are one of the most beautiful fish and that is why I have repeatedly tried to keep groups.
Bartlett's are great kept as individuals but their "desire to be male" is stronger than most species. In a 180 you will likely end up with multiple males and the aggression that comes with it, but I've seen tanks that size with 2 or 3 males do just fine. I've kept close to a dozen species of anthias and they are by far the hardiest.
