Common name: Three-spot Angelfish

General Information

The Three-spot Angelfish, scientifically known as Apolemichthys trimaculatus, is a striking addition to any marine aquarium. Known for its vibrant yellow body adorned with three distinct spots, this angelfish is a favorite among aquarists seeking a visually stunning and active fish. Its common names, "Three-spot Angelfish" and "Flagfin Angelfish," reflect its distinctive markings and elegant fin structure.

In the wild, this species is found in the Indo-Pacific region, inhabiting coral-rich lagoons and outer reef slopes. Its natural beauty and relatively hardy nature make it a popular choice for experienced hobbyists.

Care

Caring for the Three-spot Angelfish requires attention to detail, as it thrives best in well-maintained reef aquariums. It prefers a tank with plenty of live rock for grazing and hiding, mimicking its natural habitat. This species is moderately difficult to care for, requiring stable water conditions and a spacious environment.

A tank of at least 300 liters is recommended to accommodate its active swimming behavior and territorial nature. The aquarium should be equipped with efficient filtration and regular water changes to maintain optimal water quality.

Diet and Feeding

The Three-spot Angelfish is an omnivore, with a diet that includes sponges, algae, and small invertebrates in the wild. In captivity, it should be offered a varied diet consisting of high-quality angelfish preparations, spirulina, mysis shrimp, and finely chopped seafood. Providing a balanced diet is crucial for maintaining its vibrant coloration and overall health.

Feed this angelfish two to three times daily, ensuring that it receives a mix of plant-based and protein-rich foods. This approach helps replicate its natural feeding habits and supports its nutritional needs.

Behavior and Compatibility

The Three-spot Angelfish is semi-aggressive, particularly towards other angelfish and similarly shaped species. It is best kept as a single specimen or in a large tank with other non-aggressive fish. Its territorial nature means it may defend its chosen area of the tank, especially if it feels threatened.

While it can coexist with a variety of tank mates, caution is advised when introducing it to a reef tank. It may nip at soft corals and sessile invertebrates, so it is considered reef-safe with caution.

Reproduction

Breeding the Three-spot Angelfish in captivity is challenging and rarely achieved. In the wild, they form pairs during the breeding season. Successful breeding requires a large tank and specific environmental conditions to mimic their natural habitat.

Health and Common Issues

With proper care, the Three-spot Angelfish can live for several years in captivity. Maintaining stable water conditions and a balanced diet is essential for preventing common health issues such as ich and nutritional deficiencies.

When selecting a Three-spot Angelfish, look for active individuals with bright colors and clear eyes. Avoid fish that appear lethargic or have visible signs of disease.

Habitat

In its natural habitat, the Three-spot Angelfish is found in coral-rich environments across the Indo-Pacific region, from the Maldives to the Solomon Islands. It prefers areas with abundant coral growth and clear, warm waters, often seen swimming among the reefs at depths of up to 30 meters.
