About:

One of the most beautiful and desired Acanthuridae, also known as powder blue tang and powder-blue surgeonfish. Many people are amazed by its unique appearance. The fish is difficult to keep, in tanks that are not yet properly prepared for it, it often succumbs to smallpox. It’s not recommended for novice aquarists.

The fish is sensitive to water quality. Requires clean water and a tank with stable parameters, especially NO3 and PO4. After acclimatization, it can swim in the tank for years without any problems

Can be aggressive towards other fish from the same family. If there are more than one in the aquarium, they will establish a hierarchy. It’s worth letting in the generations in order from the least to the most aggressive.

Like other Acanthuridae, it likes plant food. If we don’t have algae on the rock in our tank, then, in addition to frozen foods such as mysis or artemia, we should provide it with an algae clip, which the fish will nibble on.
