A legendary reef fish renowned for its brilliant blue colouration, active nature, and iconic appearance
The Blue Tang is one of the most recognisable marine fish in the world, prized for its vibrant electric blue body, bold black markings, and bright yellow tail. Constantly on the move, Blue Tangs bring energy, colour, and life to larger marine aquariums. They are excellent grazers, helping to control nuisance algae while providing endless entertainment as they cruise through the rockwork.
While hardy once established, Blue Tangs require excellent water quality, plenty of swimming space, and a varied diet rich in marine algae. Their striking colours and active behaviour make them a true centrepiece fish for suitably sized reef aquariums.
