The Arothron Puffer is a remarkable fish, with the notable absence of pelvic fins. Despite this, it is incredibly agile and can move swiftly through the water, thanks to its pectoral, dorsal, and anal fins. Furthermore, it has a unique beak-like structure that it uses to process its food, rather than teeth. This is a truly remarkable adaptation that allows the Arothron Puffer to thrive in any environment. Additionally, the Arothron Puffer is a hardy species and can survive in a variety of water conditions. This makes it a popular choice for both beginner and experienced aquarists alike.
A 125 gallon or larger, fish-only aquarium is suitable for a beginner. It will eat invertebrates found in a reef tank. It will become alarmed when in a net, so it is best to transfer it using a container.
