Common name: Porcupinefish

The genus Diodon, commonly known as Porcupinefish, includes species well-known for their ability to inflate their bodies as a defense mechanism. These fish are characterized by their spiny appearance, which becomes more pronounced when they puff up. Porcupinefish are fascinating additions to larger marine aquariums, but they require careful consideration due to their size and potential to release toxins. They are generally peaceful but may not be compatible with small invertebrates or sessile animals.
