AS a general rule you never want to have 2 tangs from the same family, they will fight. So the familys are Paracanthurus, Zebrasoma, Acanthurus, Ctenochaetus, and Naso.
But a 480 you may be able to get some juv from the same family and have them get along. But there is some luck involved.
Ya the PB and the entire Acanthurus can be very aggresive
