About
The Pacific blue tang (Paracanthurus hepatus), made famous by the film 'Finding Dory', is a surgeonfish of the family Acanthuridae found across coral reefs of the Indian and Pacific Oceans. Its brilliant royal blue body, bold black palette marking, and yellow tail fin make it one of the most visually striking species in the marine aquarium hobby. Adults can exceed 30 cm in length, requiring a minimum 90-litre tank, ideally 120 cm or larger. Susceptible to Cryptocaryon (marine ich), it demands stable, high-quality water with specific gravity 1.023–1.025 and pH 8.1–8.4. Ample swimming space is essential for its health and well-being.
