Overview:
The Yellow Tang (Zebrasoma flavescens) is a vibrant, hardy marine fish popular among aquarists. Native to the reefs of the Pacific Ocean, particularly around Hawaii, they thrive in well-maintained saltwater aquariums. Ideally, a tank of at least 75 gallons is recommended to accommodate their active swimming behavior and territorial nature. Water conditions should be stable, with a temperature range of 72-78°F, pH between 8.1-8.4, and specific gravity of 1.020-1.025. They require ample live rock for grazing and hiding, as well as open swimming space. Strong water movement and efficient filtration are essential to mimic their natural habitat and maintain water quality.

Diet and Feeding:
Yellow Tangs are primarily herbivores, feeding on algae in the wild. In captivity, their diet should consist mainly of marine-based algae and seaweed. Offer them dried seaweed sheets (nori) attached to a clip, and supplement with high-quality spirulina-based flakes or pellets. It is beneficial to provide a varied diet that includes occasional treats of mysis shrimp or brine shrimp. Feed them small amounts 2-3 times daily to ensure they receive adequate nutrition and to prevent overfeeding, which can lead to water quality issues.

Compatibility:
Yellow Tangs are generally peaceful but can exhibit territorial behavior, especially towards other tangs or fish with similar body shapes. They are best kept as the only tang in a tank unless the aquarium is large enough to accommodate multiple tangs with ample space to establish territories. They are compatible with a wide range of other marine species, including clownfish, gobies, and wrasses. Avoid housing them with overly aggressive species or those that may outcompete them for food. Introducing them last to an established community tank can help reduce territorial disputes.

Health and Quarantine:
Yellow Tangs are susceptible to common marine diseases such as ich and marine velvet. Quarantine new arrivals for at least 2-4 weeks before introducing them to the main tank to prevent disease transmission. During quarantine, observe for signs of stress or illness, such as rapid breathing, spots, or color changes. Maintain optimal water quality and provide a stress-free environment to support their immune system. Regularly check water parameters and perform routine water changes to prevent ammonia and nitrate buildup. Supplementing their diet with vitamins and garlic can enhance their immune response and overall health.
