The Blue Tang (Paracanthurus hepatus) is one of the most recognizable and vibrant reef fish, celebrated for its dazzling blue body and striking yellow tail. Constantly on the move, it is both a functional algae grazer and a stunning centerpiece, adding beauty, color, and energy to any reef aquarium.
A mature aquarium of at least 125 gallons is essential, offering strong water flow and wide swimming spaces to match its active lifestyle. Blue Tangs should be housed singly unless kept in very large systems and introduced simultaneously, as they can become territorial.
Their diet should be primarily algae-based, featuring marine seaweed and spirulina, supported by quality herbivore preparations. Occasional additions of mysis shrimp or krill provide extra protein and variety. Regular algae feedings help maintain strong immunity, reduce stress and aggression, and preserve their brilliant coloration.
The Blue Tang is available now at Ocean in a Box, offered at the best price for your reef aquarium.
