Natural History: The Porcupine Pufferfish is found in lagoons and shallow reefs. Adults are generally found singly, wedged in caves and recesses on the reef during the day. Juveniles may move with ocean currents over great distances, dispersing this species around the globe. This puffer species is reported to be poisonous to humans, due to tetrodotoxin.
Husbandry: The Porcupine Pufferfish will feed on ornamental invertebrates in captivity. Once acclimated, it will become very tame, capable of recognizing its keeper and begging for food. Some individuals have lived over 10 years in captivity. It is reported to nip at the fins of some of its tankmates.
