Tank compatibility[edit]

Purple Tangs can be very aggressive to other Tangs, particularly to towards other Zebrosoma species.


A herbivorous fish, will take dried seaweed, marine algae, mysid shrimp, Spirulina, blanched Romaine Lettuce or fresh seaweed.

Feeding regime[edit]

Ideally they should be fed everyday with 3-4 supplemental feedings of dried algae.

Environment specifics[edit]

They are sensitive to water quality, needs an SG of 1.020 - 1.025. As with all Tangs, they need relatively large tanks, over 284 Litres (75 US G.).


It does get territorial and can be aggressive to new additions to the tank as it gets older. Should not be kept with similarly shaped Tangs.


They have a deep purple-blue body with a bright yellow tail and bright yellow accents on the pectoral fins. They have a single spine (or “scalpel”) on each side used for defence.
