Purple Tang
(Zebrasoma xanthurum)
Population status in the wild: Least Concern
The Purple Tang, also known as the Purple Surgeonfish, is a striking species of tang native to the Indo-Pacific, primarily found around coral reefs in regions like the Maldives, the Philippines, and parts of the Indian Ocean. With its deep purple body and yellow tail, the Purple Tang is known for its vibrant color and elegant appearance. This species typically grows up to 8 inches in length, making it a larger tang that requires a spacious tank to thrive, ideally 75 gallons or more.
Purple Tangs are herbivores, feeding on algae that grow on rocks, coral, and other surfaces in their natural habitat. They are important grazers in the wild, helping to keep algae populations under control and maintaining the health of coral reefs. In captivity, Purple Tangs should be provided with a diet that includes algae-based foods like spirulina, nori, and high-quality marine pellets, as well as occasional live or frozen foods like brine shrimp. Their grazing behavior helps to reduce excess algae growth in the aquarium, making them a beneficial addition to reef tanks.
While they are relatively peaceful, Purple Tangs can be territorial, especially when it comes to defending their space in the tank. They may display aggression towards other tangs or similar-looking fish, so it's best to house them with non-competitive or peaceful tankmates. Purple Tangs are best suited for larger aquariums with plenty of live rock to graze on and swim around. It is also important to provide hiding spots where they can retreat to when feeling stressed or threatened.
Purple Tangs are relatively hardy but do require stable water conditions to thrive. They prefer slightly alkaline water with moderate to strong water flow and a temperature range of 74-80°F (23-27°C). They also require high water quality, so regular water changes and proper filtration are essential. With proper care, Purple Tangs can live for 10 years or more in captivity.
Fun Facts:
The Purple Tang's vibrant coloration is one of its most notable features, making it a popular choice for aquarists looking to add color and elegance to their reef tanks.
They are equipped with sharp spines on their tail, which they can use for self-defense against predators, and they may also use these spines to establish dominance over other fish in the tank.
Despite their peaceful nature, Purple Tangs require ample space to swim and graze, and they do best in larger aquariums with plenty of live rock and hiding places.
