Arothron citrinellus - golden puffer 

The Arothron citrinellus, commonly known as the Golden Puffer, is a captivating species of pufferfish found in tropical marine environments. This fish is renowned for its vibrant golden-yellow coloration, which can vary in intensity. Its body is robust and somewhat rounded, with small, bright eyes that add to its charming appearance.

The Golden Puffer is known for its playful and curious nature. It often interacts with its surroundings and can become quite personable with its keepers in an aquarium setting. These puffers have strong, beak-like teeth that they use to crack open hard-shelled prey such as mollusks and crustaceans. It's essential to provide them with a varied diet to keep their teeth worn down, as they can grow continuously.

In the wild, the Arothron citrinellus inhabits coral reefs and rocky areas, where it can find plenty of hiding spots and food sources. In captivity, they require a spacious tank with plenty of hiding places and a well-balanced diet to thrive. Their striking color and engaging behavior make them a favorite among aquarists.
