About This Species
Famously known as 'Dory,' the Blue Tang is a stunningly vibrant fish that captures the hearts of many. With its electric blue body, bold black markings, and a bright yellow tail, it's a showstopper in any saltwater aquarium. However, its beauty comes with a high level of required care, making it a challenging fish best suited for experienced aquarium owners. These fish are incredibly active, constantly swimming and exploring every corner of their environment. They are natural grazers, spending their days nibbling on algae and other plant matter, so a diet rich in greens is essential to keep them healthy. While they can be a bit bossy and territorial, especially with similar-looking fish, they can be a fascinating centerpiece in a very large tank. A key feature to be aware of is the sharp, scalpel-like spine located at the base of its tail, which it can use for defense. This is why it belongs to the 'surgeonfish' family, and handlers must be cautious. Due to its long lifespan, owning a Blue Tang is a significant, long-term commitment that requires a dedicated and knowledgeable aquarist to provide the stable, spacious environment it needs to thrive.
