I just want to put this in perspective.
A Purple Tang should live 40- 50 years so saying yours did fine for a few years in a 55 really isn't that meaningful.
I agree that a Purple or Yellow could do fine for decades in a 55. All I'm saying is that it will be stressed and the chances of it leading a long life are severly reduced in a 4 foot tank.
