Caribbean Balloon Pufferfish (Diodon holocanthus)
A fascinating and playful addition to large saltwater aquariums, the Balloon Pufferfish is known for its unique ability to inflate when threatened, spiky texture, and expressive face. This species brings personality and a true Caribbean reef atmosphere to your tank.
Native to Caribbean reefs, lagoons, and seagrass beds, these fish thrive in spacious tanks with plenty of rockwork and hiding places. They are generally peaceful but may nip at very small or slow-moving invertebrates, making them best suited for tanks with larger, active invertebrates.
Hardy and adaptable to captivity, the Balloon Pufferfish readily accepts a carnivorous diet of meaty frozen foods such as shrimp, squid, clams, and chopped seafood. A balanced, protein-rich diet ensures optimal health and behavior.

The Balloon Pufferfish is a delightful addition to my 120-gallon reef tank. It inflates when startled and looks very expressive. I feed it frozen shrimp and squid regularly. It’s peaceful and doesn’t bother my corals or other fish.
Adrian May –
Great fish with a unique appearance. It’s active and curious. I made sure to include plenty of rockwork for shelter. It’s not aggressive, but I do avoid keeping it with very small invertebrates.

Very easy to care for. I’ve had it for six months and it’s thriving. The inflation behavior is entertaining and adds a lot of character to the tank.
