Royal Gramma Basslet Basics

Origins and Natural Habitat

The Royal Gramma fish, also known as Fairy Basslet or Gramma loreto, is native to the Caribbean. In the wild, they thrive in coral reefs where they find hiding places and play an important role in the ecosystem. Your addition of this Royan Gramma fish to your aquarium can help recreate the vibrant spectacle found in their natural habitat.

Size and Shape

These fish are relatively small, typically reaching a length of about 3 inches (7-8 cm). They have a narrow body and a torpedo-like shape, making them agile swimmers in your aquarium. Royal Grammas should have a minimum tank size of 20-30 gallons (75-113 Liters) in order to provide ample space for exploring and hiding.

Color and Markings

The Royal Gramma is well regarded for its stunning colors and striking appearances. These fish have a unique color pattern, with their bodies displaying a gradient of bright purple at the front, changing to a vibrant yellow at the rear. They also have a black line that runs through each eye, adding to their distinctive look.


A well-cared-for Royal Gramma can live for over five years in a suitable saltwater aquarium. To ensure their longevity, it’s essential to maintain a clean and healthy environment in your tank by providing proper filtration, regular water changes, and a balanced diet. By doing so, you can enjoy their beautiful presence for many years to come.

Diet and Feeding

As a royal gramma enthusiast like yourself, you know it’s essential to provide these little beauties with the right diet. Don’t worry; we’ve got some tips for you! Royal grammas are natural carnivores, but in your home reef aquarium, replicating their natural diet could be a bit challenging. Most of their nutrition will come from pellets, flakes, and frozen foods – these conveniently and affordably cover their core nutritional needs.

To spice up their meals, try adding protein-rich treats a couple of times a week. This can include goodies like frozen or dried plankton, brine shrimp, Mysis shrimp, crustacean flesh, or bloodworms. A mix of these foods offers a balanced diet and provides enrichment for your royal grammα.

Remember to avoid overfeeding them, and stick to feeding your royal gramma 2-4 times per day. Keep an eye on their food consumption, and adjust the portion size if needed. This way, your royal gramma will not only add vibrant colors to your aquarium, but it’ll also stay healthy and happy.

Behavior and Temperament

Royal grammas are known for being peaceful fish that appreciate the security of coral, reefs, and rocks in their environment. Due to their preference for hiding spots, they might display some aggression when it comes to defending their chosen territory.

In your tank, you’ll often find your royal grammas hiding and darting out to eat, rather than exploring the top or bottom of the tank. This unique behavior helps them navigate their surroundings and adds an interesting dynamic to your aquarium.

One fun aspect of their behavior is their ability to swim upside down along rocks and surfaces, which is entirely normal for royal grammas. This acrobatic feat not only showcases their agility but also aids them in easily navigating their environment.

Lastly, it’s essential to have a strong lid on your tank, as royal grammas are known to be excellent jumpers. These fish have been observed testing their escape skills multiple times, so ensuring their safety means having proper precautions in place.

Care and Tank Requirements

Tank Size

When setting up a tank for a royal gramma basslet, it’s important to consider its size. A single royal gramma requires a minimum of 20-30 gallons (75-113 liters) of water. For each additional royal gramma, you should add another 30 gallons to ensure adequate space for the peaceful reef fish.

Water Parameters

Proper water parameters are crucial for the well-being of your royal gramma basslet:

  • Temperature: 72-78°F (22-26°C)
  • pH: 8.1-8.4
  • Salinity: 1.020-1.025

Make sure you monitor these parameters closely to maintain a healthy environment for your fish.

Tank Setup and Decorations

The royal gramma basslet is a reef species that enjoys a well-structured environment. Consider incorporating various hiding spots using live rock, caves, and overhangs. This will help your fish feel secure and reduce stress.

Since they are reef-compatible, you can also include corals in the tank. Just make sure to leave enough open space for swimming.

Filtration and Aeration

A proper filtration system is essential for keeping the water clean and maintaining optimal water parameters in a royal gramma basslet tank. Ensure the filter you choose is suitable for the size of your tank and can maintain good water quality.

Aeration is also crucial for providing the necessary oxygen levels. An air pump can serve a dual purpose, as it can help with water circulation in addition to aeration. This will ensure that the water stays well-oxygenated, providing the best environment for your royal gramma basslet.

Suitable Tank Mates

When setting up a saltwater aquarium with royal grammas, it’s essential to consider their tank mates. You’ll be happy to know that these colorful fish are compatible with a variety of tank mates from different species:

  • Angelfish
  • Gobies
  • Hawkfish
  • Boxfish
  • Blue green Chromis
  • Clownfish

Keep in mind that large or aggressive fish should be avoided, as they can harm or scare your royal grammas. Species like snappers, lionfish, eels, and groupers are not recommended.

Fish that inhabit rockwork and crevices may cause territorial issues with your royal grammas, and similar-looking fish, such as royal dottybacks, can trigger territorial behavior.

When it comes to keeping multiple royal grammas, it is possible if you provide sufficient space and hiding spots. Males may exhibit more aggression towards each other than females, so be mindful of their gender when adding them to your aquarium. By following recommended tank size guidelines and considering the gender of your royal grammas, you can ensure a harmonious environment for all your fish in the tank.

Breeding Process

Breeding royal grammas is a relatively simple and enjoyable endeavor, even for beginners. To get started, you’ll need a male and female in a standard tank. There’s no need for special modifications to their habitat to encourage breeding.

The male will build a nest using rocks and vegetation over a day or two. Once the nest is ready, the female will swim over and add her eggs to it. The male then fertilizes the eggs. Typically, the eggs will hatch within a week.

After the eggs have hatched, your focus should be on providing food and ensuring the young fish grow properly. Breeding royal grammas doesn’t require extensive experience, so it’s an accessible and rewarding process for those interested.

In summary, the breeding process for royal grammas involves the male constructing a nest, the female depositing eggs, and the male fertilizing them. By following these steps, you can successfully reproduce these beautiful fish in your own tank.

Common Diseases and Treatments

Royal grammas are hardy and resilient, which means they are not typically prone to species-specific diseases or illnesses. However, like any other saltwater fish, they can still be affected by common ailments. To protect your royal gramma basslet from these issues, your best bet is to maintain good water quality.

By ensuring proper water conditions in your aquarium, you’re taking a big step towards keeping your royal grammas healthy. It is vital to conduct regular water testing to monitor parameters like temperature, salinity, pH, and ammonia levels. Monitoring these conditions will help you prevent most fish-related ailments in your royal gramma population.

Having a quarantine tank for new fish or sick fish is a good idea, as it provides a controlled environment for observation, diagnosis, and treatment. Since regular water maintenance is crucial, make sure you have a proper schedule to keep your aquarium in optimal conditions.

Remember, prevention is always better than cure, so stay diligent and proactive in maintaining your aquarium to ensure the health and well-being of your royal grammata basslet.
