Gem Tang (Zebrasoma gemmatum) Care
The Gem Tang, Zebrasoma gemmatum, is also known as the Spotted Tang and the Spotted Sailfin Tang. These fish come from the Western Indian Ocean. They have brown/black body with lots of tiny bright white spots and a beautiful yellow tail. Tangs are also known as surgeonfish because they have a scalpel-like spine at the base of the tail, be sure to handle them with care!
Tangs are herbivores and require a diet rich in foods such as macroalgae, dried seaweed, and enriched vegetable flakes. They should be fed a couple of times a day. Despite being herbivores, they will happily eat meaty foods fed to other tank inhabitants. If there are insufficient algae on the rocks, it is important to feed more frequently and supplement with algae rich food such as Spirulina or Ogo.
Gem Tangs can reach up to 9″ and require an aquarium of at least 180 gallons with strong water flow and lots of swimming area. They will be peaceful with almost all fish EXCEPT other tangs. If you want to add multiple tangs to a tank, it is best to add them at the same time so none of them have pre-established territories. They require places to hide, especially when newly introduced into the aquarium.
They are reef safe.
NOTE: Tangs are very susceptible to getting ich; always quarantine them before introducing them to your main tank.
