Gramma loreto
The Royal Gramma, *Gramma loreto*, is a captivating and popular Basslet known for its striking coloration. Its anterior half is a vibrant purple, transitioning sharply to a brilliant yellow on the posterior half, including the tail fin. This distinct two-tone pattern makes it easily recognizable and a favorite among hobbyists.
A minimum of a 30-gallon aquarium is recommended for a single Royal Gramma, providing ample swimming space and plenty of rockwork with crevices and caves for hiding. They are generally peaceful and make excellent additions to community tanks. While they are considered reef-safe, they may occasionally nip at very small, sessile invertebrates if not well-fed.
The Royal Gramma is a protogynous hermaphrodite, meaning they are born female and can change to male. Breeding in captivity is possible but requires specific conditions. There are no easily distinguishable visual differences between males and females. Their diet should consist of a variety of meaty foods, including mysis shrimp, brine shrimp, and other high-quality marine frozen foods. They will also accept flake and pellet foods. In a home aquarium, they typically reach a size of about 3 inches.
