I'm going to upgrade to a 180 gal tank from 125. I currently have a PBT, purple tang and sailfin tang. The purple tang is a bit aggressive but I feel hes just defending territory. When I first got the purple tang I had it in QT with the PBT and they never had an issue together and they never messed with each other in the DT. I wanna add a yellow tang and possibly a blue hippo. Do you think if I took them all out and had them in QT or left them in my current 125 and took all the rock out and added it to the 180 build then introduced them all at the same time this would be fine? or do you think that I'm pushing my luck?
