Overview
- Native to the deep reefs of the Western Atlantic, particularly in the Caribbean.
- Recognized for its deep purple body with a bold black cap extending from the snout to the dorsal fin.
- Closely related to the Royal Gramma but tends to be more reclusive and territorial.
- Prefers to stay near rocky overhangs and caves for shelter and security.
- One of the most striking basslets, making it a popular choice for reef aquariums.
Feeding
- Carnivorous diet consisting mainly of zooplankton, small crustaceans, and copepods.
- Readily consumes frozen and live foods such as mysis shrimp and brine shrimp.
- Can be trained to accept high-quality pellets and flakes over time.
- Requires multiple small feedings throughout the day for optimal health.
- Occasionally scavenges among rockwork, feeding on microfauna and detritus.
Habitat
- Found at depths of 10-100 meters in rocky reef crevices and coral caves.
- Requires an aquarium with ample rock structures to provide hiding places.
- Prefers dimly lit environments but will explore more once acclimated.
- Best suited for reef tanks with stable water conditions and low aggression.
- A minimum tank size of 30 gallons is recommended to support its territorial nature.
Fish Care
- Optimal water temperature: 74-80°F (23-27°C).
- Ideal pH range: 8.1-8.4, with a specific gravity of 1.023-1.026.
- Resilient and hardy but requires high water quality to prevent stress.
- Can be territorial, especially toward similar-sized basslets and grammas.
- Regular water changes and a stress-free environment promote long-term health.
Compatibility
- Peaceful with most tank mates but may be aggressive toward its own species.
- Compatible with clownfish, gobies, wrasses, and other non-aggressive fish.
- Best kept singly unless in a very large aquarium with multiple territories.
- Reef-safe and does not harm corals, making it an excellent addition to reef tanks.
- Should not be housed with large predators that may view it as prey.
Aquarium Behavior
- Prefers to stay near rock formations, retreating into caves when startled.
- Can be shy at first but becomes more active once acclimated.
- May exhibit territorial displays toward fish encroaching on its space.
- Known for its unique hovering and darting swimming style.
- Thrives in an environment with plenty of shelter and minimal tank aggression.
