Spiny Box Puffer (Web Burrfish)
The Spiny Box Puffer has a tan to yellow body with dark spots and short, fixed spines that provide protection against larger, more aggressive fish. It features a fused beak-like structure for feeding.
Requires a 180-gallon or larger aquarium with ample swimming space. Best suited for fish-only tanks. May nip at slow-moving or long-finned fish, but is generally peaceful with members of its own species. Will consume invertebrates commonly found in reef environments.
Feeding should include a varied diet of meaty foods such as squid, krill, clams, and hard-shelled shrimp to help wear down its continuously growing teeth.

The Spiny Box Puffer is a unique and interesting addition to my tank. It’s active and curious, and I’ve noticed it enjoys feeding on clams and shrimp. The tank is large enough, and I’ve kept it separate from long-finned fish to avoid nipping. Feeding it daily with squid and krill has helped maintain its dental health.

It’s a striking fish with a distinct appearance. I’ve had it for three months now and it’s adapted well to the environment. I feed it a mix of meaty foods every day, and it seems to be thriving. Just make sure to keep it in a spacious tank with no vulnerable fish nearby.

The fish is active and looks healthy, but I’ve noticed it occasionally nips at the edges of my tank. I’ve moved it to a corner with no long-finned fish nearby. Feeding it a variety of meaty foods has helped with its teeth wear. Overall, it’s a good choice for experienced aquarists.
