The most coveted of the basslets, the Royal Gramma Basslet or Fairy Basslet is beautiful. The front half of its body and head are a bright purple to violet, while the back half is a striking and vibrant yellow. It is an excellent choice for a reef aquarium, and since it remains small, is perfect for small reef systems.

A single specimen should be housed in a minimum of a 30 gallon tank. They are aggressive towards their own species, and should be housed singly. Because the Royal Gramma Basslet is a deep-water dweller, it prefers caves and extensive rockwork, as well as a somewhat subdued lighting arrangement.

As a carnivore, the Royal Gramma Basslet will do well on a diet of meaty fare including marine fish, crustacean flesh, mysid shrimp, and quality frozen preparations.
