Care
The Yellow-ear Angelfish requires a well-maintained aquarium with plenty of hiding spaces and live rock to graze on. A tank of at least 500 liters (130 gallons) is recommended to accommodate its active swimming habits and territorial nature. This angelfish thrives in a stable environment with pristine water conditions, including proper filtration and regular water changes.
Aquarists should be aware that this species may nip at corals and sessile invertebrates, making it a less ideal candidate for reef tanks. However, it can coexist with a variety of other marine fish species if introduced carefully and provided with ample space.
Diet and Feeding
In the wild, the Yellow-ear Angelfish is an omnivore, feeding on sponges, tunicates, and algae. In captivity, it should be offered a varied diet that includes high-quality angelfish preparations, marine algae, and frozen foods like mysis shrimp and brine shrimp. Regular feedings with a diverse diet will help maintain its health and vibrant coloration.
Feed the Yellow-ear Angelfish two to three times a day, ensuring that it receives enough nutrition to support its active lifestyle. Providing a balanced diet with occasional supplements can help prevent nutritional deficiencies and promote longevity.
Behavior and Compatibility
The Yellow-ear Angelfish is semi-aggressive and may exhibit territorial behavior, especially in smaller tanks or when housed with similar species. It is best kept with other semi-aggressive or peaceful fish that can hold their own, avoiding overly aggressive tank mates that might stress or outcompete it for resources.
While not considered reef-safe, the Yellow-ear Angelfish can be a stunning addition to a fish-only or fish-with-live-rock aquarium. It is important to monitor its interactions with other tank inhabitants to ensure harmony and reduce stress.
Reproduction
Breeding the Yellow-ear Angelfish in captivity is a challenging endeavor that has not been widely achieved. Little is known about their specific breeding habits in the wild, and they require specific conditions that are difficult to replicate in home aquariums.
Health and Common Issues
The Yellow-ear Angelfish is generally hardy but can be susceptible to common marine diseases such as ich and marine velvet. Maintaining excellent water quality, providing a balanced diet, and observing for signs of stress or illness are crucial for its well-being.
Regular health checks and quarantine of new additions can help prevent the introduction of diseases. Prompt treatment of any health issues is essential to ensure the longevity and vitality of this beautiful species.
Habitat
Naturally found in the coral reefs of the Red Sea and the Arabian Peninsula, the Yellow-ear Angelfish prefers rocky areas with plenty of crevices to explore and hide in. It thrives in warm, stable water conditions that mimic its natural environment, with moderate water flow and ample opportunities for grazing on algae and invertebrates.
