How long would you let the present yellow tang follow and attempt tail slapping the new white tail bristletooth? The white tail has been in acclimation box for 5 days with no aggression from the tank mates. Decide to open the door about 10 minutes ago. The yellow tang keeps trying to slowly get close and tail slap. Maybe try a mirror? Or should I attempt to catch one of the tangs and put back in acclimation box? Also lights are on currently? Should I turn lights off? I feel like that’s just delaying the current situation? New to tangs so what’s the best way to settle them in and coexist?

. Note I cut this out in about 3 minutes so top quality
