Tank compatibility[edit | edit source]

Should not be kept with similar looking fish or with fish with the same feeding habits. Other species of Tang are not recommended as the Powder Blue can be territorial. The Powder Blue should be the only Tang-like fish in the system. Fish that do not resemble it should be fine however and should be peaceful yet robust.

Diet[edit | edit source]

Will mainly graze on algae and spirulina, and may also take lettuce, dried seaweed and zucchini. When buying these fish be aware that stock can easily starve, do not buy fish with sunken bellies.

Feeding regime[edit | edit source]

Feed 2-3 times a day.

Environment specifics[edit | edit source]

Behaviour[edit | edit source]

Active and territorial.

Identification[edit | edit source]
