Care Guidelines: The Chocolate Tang requires a spacious aquarium of at least 125 gallons to accommodate its active swimming behavior and potential size. Provide ample live rock formations to offer hiding spots and grazing surfaces. Maintaining high water quality with stable parameters is crucial, as this species can be sensitive to fluctuations.

Diet: Primarily herbivorous, the Chocolate Tang thrives on a diet rich in marine-based algae and seaweed. Supplement their diet with high-quality flake or pellet foods formulated for herbivorous fish. Offering dried seaweed tied to a rock or using a veggie clip at least three times per week will help strengthen their immune system, reduce aggression, and improve overall health.

Compatibility: Generally peaceful, the Chocolate Tang coexists well with other non-aggressive species. However, it may exhibit territorial behavior towards conspecifics or similarly shaped fish, especially in smaller tanks. Introducing multiple specimens simultaneously into a larger marine system can help mitigate aggression.

Special Considerations: Regular monitoring for signs of stress or disease is essential, as this species is susceptible to common marine ailments. Quarantining new additions and maintaining optimal water quality can help prevent these issues.

By adhering to these care guidelines, the Chocolate Tang can be a vibrant and engaging addition to your marine aquarium, offering both aesthetic appeal and dynamic behavior.
