Stars & Stripes Puffer (Arothron hispidus)
The Stars & Stripes Puffer is a semi-aggressive fish that is not compatible with reef tanks. It will consume invertebrates and requires a minimum tank size of 72 inches (180+ gallons) when fully grown. The tank should provide ample swimming space and include a reliable protein skimmer for efficient nutrient control.
This species can inflate its body when threatened or frightened. It is essential to transfer the puffer from the shipping bag to the aquarium or acclimation container while submerged, using a bag or container instead of a net. Inflating the fish with air rather than water can pose health risks.
The diet should consist of meaty foods such as krill, squid, clams, and hard-shelled shrimp to support dental health and natural tooth wear. The maximum adult size is approximately 18 inches.

Una McGrath –
The puffer arrived healthy and was easy to acclimate. I made sure to transfer it underwater as instructed. It’s active in the tank and eats regularly on squid and clams. The tank is large enough and the protein skimmer works well. Only issue is it occasionally inflates when startled, but it’s not harmful.
Nicola Newman –
I followed the instructions carefully. The fish is semi-aggressive and needs a big tank. It eats meaty foods well and has adapted to the environment. I didn’t see any signs of aggression toward other fish, though it does chase small prey.
David Wilson –
The puffer is active and eats well, but I noticed it inflates when the tank is disturbed. I made sure to handle it underwater. The tank size is large, and I use a protein skimmer. It’s not ideal for a small setup, but works fine in a spacious tank.
