There are more than just two species of Porcupine Puffers but yes, out of the commonly available ones, the Diodon hystrix is one of the biggest. They can reach close to 3 feet. The public Aquarium I am a member of, has one about 2.5'. This Porcupine Puffer is obviously not the best species to be kept by most of us in our small aquariums. These guys are generally more spotted than Diodon holacanthus, which is the species most people have.
Diodon holacanthus stays around 10" or up to about 12" in the wild. So much better to have at home.
