The Purple Tang (Zebrasoma xanthurum) is one of the most prized marine species for saltwater aquariums or reef tanks. In nature they are found among coral rich areas in the Red Sea, as well as more recently the Arabian Sea, the Gulf of Aden and Sri Lankan waters. A popular choice among saltwater and reef aquarists, it is known also known as the Yellowtail Tang and the Dusky Sailfin Tang. Why is it an all-time favorite? Because of its stunning coloration. The Purple Tang is blue to purple in color with a yellow tail and yellow accents on their pectoral fins. As juveniles, they display horizonal striping, but that eventually fades away. Adults can reach a length of ten inches. Its small and numerous pharyngeal teeth allow it to eat filamentous algae found in coral, rocks, and crevices.

Yes, Purple Tangs are reef safe. In addition to them being a favorite specimen for saltwater tanks, they are one of the most popular choices among reef aquarists.

Purple Tangs are semi-aggressive. They should not be housed with other Tangs in the Zebrasoma genus, and they may also become territorial when protecting the places where they sleep. When stocking an aquarium, it is recommended to introduce the Purple Tang last.

If housed properly, the Purple Tang is a rewarding and attractive addition to any large saltwater or reef aquarium. The aquarium where they are housed should have adequate lighting, lots of free-swimming space, and plenty of potential hiding spots.

Providing stable water parameters is important. A minimum size tank of one hundred twenty five gallons is required, with specific gravity between 1.020-1.025. Temperature should be kept at 72-78° F, and hobbyists should maintain a dKH of 8-12, and a pH balance between 8.1 and 8.4. In addition, they require strong water flow, as well as room for them to swim freely. It is important to carefully handle them to avoid their caudal spines, small scalpel like projections that can cause cuts or abrasions.

The Purple Tang is hardy and not a particularly difficult species to maintain in aquaria. If housed in optimal housing conditions and fed the right foods, it may live for ten years or more.

This member of the Acanthuridae family is an herbivore that will eat filamentous algae that is present in the aquarium but should be fed plenty of marine-based seaweed and algae at least three times per week. Because of their high activity level, these algae eaters are constant grazers.

For aquarists who are searching for an impressive fish to add a stunning impact to their aquarium, consider the Purple Tang. With its eye catching color, it creates a dominant presence in its underwater environment.
