That’s what I was trying to determine. My plan was for the broomtail to go in the 160 for now and the harlequin to go in the 210. But I have been moving fish out of the XXL750 into the 3XL900 that has been fallow. Might have gotten ahead of the schedule but had to free up my QT for a batch of tangs and wrasses for my Frag system. Just moved a rather larger Panther Grouper over last night and didn’t want to put any more strain on the bio load.The sunset is not going to be happy with the new additions. Do you have an acclimation box?
Tusks and broomtails typically do not get along so these two being together likely won't work out long term. The tusk and sunset should be fine together once the sunset gets over having new guys in his territory.
May have to move the broomtail (if I can catch him) in a week or two.
