Once my new system (270g 84"x30"x25") is up an running for several months I plan to add a few tangs. But I have questions. I 100% QT all my fish. But how should I go about adding let's say 5 tangs into a system? My plan was a 10g QT for each tang and once QT is complete, place all tangs in the DT. Does this sound correct? Is there a better way? Can I add tangs over time or do they have to be added together for the most success? I know they can be jerks and I normally use a mirror to distract my Kole Tang if he gets aggressive with a new fish. Just looking to see how others have done it. Any info is appreciated!
