When snorkeling in Hawaii you are sure to spot many of these brightly colored fish. They are very friendly and smaller in size. Their max size is 20cm. Yellow tangs, along with other algae feeders, are crucial parts of coral reef ecosystems. They feed on algae and seaweed that grow on the reefs, preventing them from overgrowing and killing corals. Yellow tangs are also a food source for larger fish and invertebrates. This pendant is available in either 14kt white or yellow gold. It has a diamond in the eye.
