Overview
- Native to the Indo-Pacific, commonly found in coral reefs, lagoons, and rocky reef slopes.
- Easily recognized by its striking yellow front half and deep blue rear half, creating a bold contrast.
- A moderately active species that requires a well-structured tank with live rock for hiding and grazing.
- Can be territorial, especially toward other dwarf angelfish, requiring careful tankmate selection.
- Best suited for an established marine aquarium with plenty of swimming space and hiding spots.
Feeding
- Omnivorous, feeding on algae, sponges, and small crustaceans in the wild.
- Accepts high-quality marine pellets, frozen foods, and algae-based diets in captivity.
- Providing sponge-based foods enhances long-term health and vibrant coloration.
- Multiple small feedings per day ensure proper nutrition and energy levels.
- A well-balanced diet prevents malnutrition and promotes a strong immune system.
Habitat
- Prefers reef environments with abundant hiding places and rocky formations.
- Thrives in stable water conditions with moderate to strong water flow.
- Aquarium setups should include live rock structures for grazing and shelter.
- Requires a well-maintained marine tank to reduce stress and promote natural behavior.
- Providing shaded areas and multiple caves helps the fish feel secure.
Fish Care
- Optimal water temperature: 74-80°F (23-27°C) for maintaining good health.
- Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
- Requires efficient filtration and regular water changes to maintain water quality.
- Introducing to an established tank helps reduce stress and improves acclimation.
- Providing a structured environment with caves and crevices supports natural behavior.
Compatibility
- Can be semi-aggressive, particularly toward other dwarf angelfish.
- Compatible with tangs, wrasses, and other semi-aggressive reef fish.
- Not entirely reef-safe, as it may nip at corals and invertebrates.
- Should not be housed with overly aggressive fish that may stress or outcompete it for food.
- Providing ample swimming space and defined territories helps minimize aggression.
Aquarium Behavior
- An active swimmer that frequently explores its surroundings.
- Often seen darting in and out of rock formations while grazing on algae.
- Can display territorial behavior, especially in smaller aquariums.
- Providing live rock formations and a well-structured tank setup supports natural behaviors.
- Over time, it may become more comfortable with its caretaker and display interactive behaviors.
