For a home tank, the most important criteria IMHO is to just give it a home free from other tangs. They'll have plenty to graze on if you don't have a lot of other algae eaters. These are not as tough as some people make them out to be.
For what it's worth a PBT will harass any butterflyfishes or angelfishes (and certainly tangs, which would be a mistake IMO) that you plan on adding later. They can be very aggressive.
