Habitat and Natural Range

The Rock Beauty Angelfish is native to the warm and tropical waters of the Western Atlantic Ocean. They are primarily found in regions ranging from Florida to Brazil and throughout the Caribbean Sea. In their natural habitat, they inhabit coral reefs, rocky outcrops, and crevices, often seeking shelter among the rocky formations and corals.

Reef Compatibility

While the Rock Beauty Angelfish is undoubtedly a striking addition to a saltwater aquarium, it's crucial to note that they are not considered reef-safe. These angelfish have a natural inclination to nip at sessile invertebrates such as corals and certain sponges. Therefore, keeping them in a fish-only or a FOWLR (Fish Only With Live Rock) aquarium is advisable, where they can thrive without threatening corals and other immobile marine life.

Size and Lifespan

Rock Beauty Angelfish are relatively small compared to other angelfish species, typically reaching lengths of up to 8 inches (20 centimeters) in captivity. They can have a lifespan of 10 to 15 years with proper care, providing aquarium keepers with years of enjoyment and beauty.

Diet in Captivity

To ensure your Rock Beauty Angelfish's health and vibrancy, providing a well-balanced diet that mimics their natural feeding habits is crucial. Offer the following foods in their daily diet:

• High-Quality Marine Pellets: Rock Beauty Angelfish can be trained to accept high-quality marine pellets designed for omnivorous marine fish.
• Frozen and Fresh Foods: Supplement their diet with various frozen and fresh offerings, such as brine shrimp, mysis shrimp, krill, and enriched frozen preparations.
• Vegetable Matter: As omnivores, these angelfish benefit from marine algae and plant matter, such as seaweed sheets or clips. This provides essential nutrients and helps maintain their health.

Aquaculture and Availability

While some Rock Beauty Angelfish are available through aquaculture, a significant portion of the aquarium trade is still sourced from the wild. To promote responsible and sustainable practices, choosing reputable suppliers like Saltwaterfish.com is advisable.

Compatibility with Other Fish and Invertebrates

Rock Beauty Angelfish can be somewhat territorial and may display aggression towards other angelfish or similar-looking species. However, with careful consideration, they can coexist with compatible tankmates. Here are five species that can be compatible with Rock Beauty Angelfish:

• Yellow Tang (Zebrasoma flavescens): Yellow tangs are known for their peaceful nature and can coexist in larger aquariums with Rock Beauty Angelfish.
• Blue Damsel (Chrysiptera cyanea): These small, colorful fish are generally compatible with Rock Beauty Angelfish.
• Sergeant Major Damselfish (Abudefduf saxatilis): These hardy fish can share an aquarium with Rock Beauty Angelfish without significant issues.

• Harlequin Tuskfish (Choerodon fasciatus): In sufficiently large aquariums, Harlequin Tuskfish can coexist with Rock Beauty Angelfish.

Sexual Dimorphism

Rock Beauty Angelfish does not exhibit significant sexual dimorphism, making it challenging to distinguish between males and females visually.

Juvenile to Adult Coloration Changes

Juvenile Rock Beauty Angelfish have a distinctive appearance, characterized by their vibrant yellow bodies and striking black vertical bars that extend from the back to the belly. As they mature into adults, their coloration transforms. Adult Rock Beauty Angelfish develop a striking pattern with bright yellow bodies and a distinctive blue-black mask covering their eyes and upper body. The adult Rock Beauty Angelfish's vibrant colors and unique patterns make them a standout species in any aquarium.

• Water Conditions: Maintain stable water conditions with the following parameters:
• pH: 8.1 to 8.4
• Salinity: 1.020 to 1.025
• Water Temperature: 74°F to 78°F (23°C to 26°C)
