I think an P. antennata would a good choice, as long as tankmates are compatible.
I haven't kept PBTs, but understand they can be very touchy with ich. If you decide to get one, I'd look for a healthy and eating specimen, be sure to QT a good long time, and add before the yellow tang. I'd choose a tang with a better chance of long term survival, but understand why you'd want a PBT - they are gorgeous.
