First off welcome too AA.
Which porcupine puffer D. Holocanthus or Hystrix(spelling?)?Here's a good list that might help ya:
smallish puffer(dog face?)
Just some basic ideas there
you possibly could get away with those two only. The puffer needs a 90 gallon and the trigger a 75 gallon tank. What kind of filtration do youhave or are planning on? These are messy eaters and you`ll need good biological and mechanical filtration.
