Spiny Box Pufferfish (Chilomycterus schoepfi)
The Caribbean Spiny Box Pufferfish is a unique and eye-catching addition to large saltwater aquariums. Known for its rounded, spiny body and expressive face, this species adds character, curiosity, and a touch of Caribbean reef charm to your tank.
Native to Caribbean reefs, seagrass beds, and sandy bottoms, Spiny Box Puffers appreciate plenty of hiding spots among rockwork and open sand for resting. They are generally peaceful but can be territorial with smaller fish or invertebrates and may nip at coral 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.

The Spiny Box Pufferfish is a striking addition to my 120-gallon tank. It’s active and curious, often exploring the rockwork and sand areas. I feed it frozen shrimp and squid regularly, and it eats well. It’s peaceful with larger fish but I’ve had to keep it away from small shrimp and snails.

Great visual appeal with its spiny body and expressive face. I’ve had it for six months and it’s adapted well to the tank. Feeding is straightforward with frozen foods. Just make sure there are plenty of hiding spots to reduce stress.

This fish adds a lot of charm to the tank. It’s not aggressive and stays mostly in the back areas. I noticed it occasionally nips at a soft coral, so I’ve moved it farther away. Overall, a satisfying and unique species.
