Balloon Puffers/ Spiny Porcupine Fish

The Caribbean Balloon Pufferfish (Diodon holocanthus) is a fascinating and playful addition to large saltwater aquariums. Known for its unique ability to inflate when threatened, spiky texture, and charmingly expressive face, this species adds personality and a true Caribbean reef feel to your tank.

Native to Caribbean reefs, lagoons, and seagrass beds, Balloon Puffers appreciate plenty of swimming space along with rockwork and crevices for shelter. They are generally peaceful but may nip at very small or slow-moving invertebrates, so care should be taken in reef setups.

This species is hardy and adapts well to captivity, readily accepting a carnivorous diet of meaty frozen foods such as shrimp, squid, clams, and chopped seafood, along with high-quality prepared foods. Its distinctive appearance, playful behavior, and interactive nature make it a captivating choice for experienced hobbyists with established fish-only or FOWLR aquariums.
