The Royal Gramma brings a burst of colour to any saltwater aquarium. It has a bright purple to violet coloured anterior contrasted by a vibrant yellow posterior. Coveted for both its unique colour pattern and relatively small adult size, the Royal Gramma is a great beginner fish that well suited for small nano reef systems.
Native to the deep-water reefs of the Caribbean, this member of the Grammidae family prefers extensive rockwork caves in which to hide and somewhat subdued lighting. Since it demonstrates territorial aggression towards its own kind, the Royal Gramma should be housed singly unless houese in a larger aquarium. However, most Royal Gramma are peaceful towards tankmates of similar size and temperament.
Since it is a carnivore, feed a varied diet of meaty fare, including brine shrimp, mysis shrimp, and quality frozen preparations.
This species can be confused with the Brazilian Gramma (G.brasiliensis).
