Anthias acclimation

[running scott]

I am trying to add some lyre tail Anthias to my tank. It's 168 gal mixed reef with a blue tang , yellow tang, blue throat trigger, flame hawkfish, 2 yellowtail damsels, Royal gramma, splendid dotyback, sunrise dottyback, and a hoevens wrasse. How would one add a group of 4 Anthias to the tank? I'm thinking either at night while all the fish are asleep, or some kind of acclimation box inside the tank.
