Zebrasoma gemmatum

The Gem Tang, scientifically known as Zebrasoma gemmatum, is a breathtaking and highly coveted fish species that belongs to the Acanthuridae family. This marine beauty is renowned for its vibrant colors, distinct patterning, and regal appearance. A rare and highly-sought after surgeon fish. The gem tang is gorgeous and striking. A stunning black body is adorned with a starry array of white spots. Bold yellow tail and accents along the pectoral fin add a burst of color. One of the most coveted fish in the marine aquarium trade, this fish when taken care of properly is a rewarding and attractive addition to any marine aquarium.

Originating from the waters around Madagascar and the surrounding islands in the Indian Ocean, the Gem Tang showcases a mesmerizing combination of vivid blue and yellow hues. Its body is elongated and laterally compressed, with a striking diamond-shaped pattern on its sides, outlined by a vibrant blue coloration.

This species is relatively larger in size compared to other tangs, reaching an average length of around 8-10 inches (20-25 cm) when fully grown. Its body is predominantly yellow, with a brilliant blue coloration on its head, face, and dorsal fin. The diamond-shaped pattern on its sides is composed of alternating blue and yellow lines, creating a stunning visual display.

The Gem Tang is known for its active and agile swimming behavior, gracefully maneuvering through the water column. It requires ample swimming space and a well-established reef or marine aquarium with plenty of hiding spots and live rock formations to mimic its natural habitat.

When it comes to feeding, the Gem Tang is primarily herbivorous, feeding on various types of algae and seaweed in the wild. In a home aquarium, it should be provided with a varied diet consisting of high-quality marine-based foods, such as algae sheets, spirulina flakes, and other herbivore pellets or flakes. Supplementing their diet with fresh vegetables, like blanched spinach or seaweed, can also be beneficial for their overall health and well-being.

Providing optimal water conditions is crucial for the well-being of the Gem Tang. They prefer a well-maintained aquarium with stable water parameters, including a temperature range of 72-78°F (22-26°C) and a pH level of 8.1-8.4. Regular water changes and the use of a good filtration system are essential to maintain water quality.

While the Gem Tang is generally peaceful, it may exhibit territorial behavior towards other tangs or similar-looking species. It is recommended to introduce them to the aquarium as the last addition to minimize aggression. Keeping only one Gem Tang per aquarium is usually advised, unless you have a very large tank with ample swimming and territorial space.

Overall, the Gem Tang is a captivating and highly sought-after addition to any reef or marine aquarium. Its vibrant colors, distinct patterning, and regal appearance make it a true gem and a favorite among aquarium enthusiasts. With proper care, a suitable environment, and a well-balanced diet, the Gem Tang can thrive and become the crown jewel of your aquatic display, adding beauty and elegance to your underwater world.

Use caution when housing with other Tangs or Surgeonfish. Similar shaped Tangs can be very aggressive towards each other. Although Tangs will eat meaty foods along with the other fish in the aquarium, it is important that they are offered plenty of marine based seaweed and algae.

Tang's can typically get along if they are not the same species and/or ample living space is provided given they are introduced at the appropriate size & time. The powder blue tang can be aggressive, especially when larger so often times it is the last fish that a reef keeper will add. 

As with all marine fish, tangs will benefit from a healthy diet of Live Phytoplankton.
