I recently tried to add a sailfin to my established reef and my powder blue wasn’t into it. Tried an acclimation box for the sailfin, after a day or two released him and powder blue at it again. This time I tried getting the powder blue out and saw the recommendation to sump the aggressor to show him who’s boss and make him reestablish dominance. He’s been in there almost 48 hours, how long should I leave him in there before putting him back in the tank? All my other tangs are happy with my new addition, just the powder blue causing problems. Any recommendations for adding him back in, turn off lights or time of day to reintroduce him? Thanks!
