Hi guys, my tank is empty right now and I want to buy more tangs. Currently, i have a powder blue tang in my sump which i move it there from the display tank about 2 months ago. I had move it to the sump is because it is a bully to other tangs. If i want to add more tangs like a clown tang, should i move the powderblue when the clowntang is in the main display?
