Get 3 females as young as you can. One will change to male. Just be forewarned that a female in transition to a male will be an absolute butthole to the females until the transition is done. After that, just minor aggression towards the females to keep them from transitioning. It's actually fascinating to witness, and the male will do mating dances daily with the females...
Carberryi get pretty big too. Dispars are nice, and smaller.
justinky: I did a QT regimen in a 55g tank with a trio of lyertails a year or so back. They survived, but could definitely benefit with more space. I don't doubt that they would've appreciated more that 20 additional gallons. They are very active swimmers...
You bring up a good point, and good on ya for taking it into consideration... I'd consider a smaller species of anthias like the dispar. I am not absolutely sure, but I believe they are just slightly less active and less aggressive than the lyertail...
Best of luck...
According to Liveaquaria they only get 3 inches at max size, require 70 gallon vs. 120 gallon tank? :hmm3:
