Common name: Yellowlined basslet

General information

The Royal Gramma, Gramma loreto, is a small and vibrantly colored fish that is a favorite among reef aquarium enthusiasts. Its front half is a brilliant purple, while the posterior is a bright yellow, creating a striking contrast. This species is not to be confused with its close relative, the Gramma linki, which has a similar coloration but with a more gradual transition between the purple and yellow hues.

Native to the tropical western Atlantic, including the Caribbean, the Royal Gramma is often found in coral reefs and rocky crevices. It is a peaceful fish that can coexist with a variety of tank mates, making it an excellent choice for community tanks.

Care

Royal Grammas are hardy and adaptable, making them suitable for both novice and experienced aquarists. They require an aquarium with plenty of rockwork and hiding places to feel secure. A stable environment with consistent water quality is essential for their well-being. They are omnivores and will accept a wide range of foods, including frozen and live meaty foods, as well as some plant-based foods.

Reproduction

In the home aquarium, Royal Grammas are known to spawn readily if they are well cared for. They are protogynous hermaphrodites, meaning they are born female and can change to male if no male is present. They lay their eggs in a sheltered spot, and the male guards them until they hatch.

Habitat

Royal Grammas are found at depths ranging from 1 to 60 meters (3 to 197 feet) in their natural habitat. They prefer overhangs and caves where they can dart in and out to catch food or evade predators. Their geographical distribution spans from Bermuda and the northern Gulf of Mexico to the Lesser Antilles and northward to the Bahamas.
