The Royal Gramma is considered reef safe, making it a suitable choice for reef aquariums. It rarely bothers corals or other invertebrates.

Size:

The Royal Gramma typically grows up to 3 inches in length, making it a relatively small fish for aquariums. Its small size allows it to fit well in smaller tanks.

Temperament:

The Royal Gramma has a semi-aggressive temperament. While it generally gets along with other peaceful fish, it may exhibit territorial behavior towards similar-looking fish or other small fish.

Sexual Dimorphism:

There is no discernible difference in appearance between male and female Royal Grammas. Both sexes share the same vibrant purple and yellow coloration.

Lifespan:

Diet in Aquariums:

The Royal Gramma is a carnivorous species that feeds primarily on small crustaceans and zooplankton. In an aquarium, it can be fed a varied diet consisting of high-quality frozen or live foods, such as brine shrimp, mysis shrimp, and small marine pellets.

Aquascaping Recommendations:

Providing plenty of hiding places and caves is essential for the Royal Gramma. They enjoy darting in and out of rock formations and crevices. Live rock with ample hiding spots and caves mimics their natural habitat and enhances their overall well-being.

Captive Bred Availability:

The Royal Gramma is available as captive-bred specimens, which are generally hardier and better acclimated to aquarium life. Captive-bred fish also help conserve wild populations and reduce the impact of collection on natural habitats.

Compatibility with Other Fish, Invertebrates, or Corals:

The Royal Gramma is generally compatible with a variety of tankmates. However, caution should be exercised when keeping them with other basslets or similar-looking species, as territorial aggression may occur. Here are 5 specific tankmates that can be good choices:

• Pajama Cardinalfish: Peaceful and colorful, they make great tankmates and add visual interest.
• Firefish Goby: Their vibrant colors and peaceful nature complement the Royal Gramma well.
• Cleaner Shrimp: They help maintain the tank’s cleanliness and also serve as an interesting addition.
