Common name: Blue-spotted Angelfish

General Information

The Blue-spotted Angelfish, scientifically known as Chaetodontoplus caeruleopunctatus, is a striking marine species admired for its vibrant coloration and unique pattern of blue spots. This angelfish is a relatively rare find in the aquarium trade, making it a prized addition for enthusiasts seeking to add a splash of color to their marine setups. First described in the late 20th century, this species has captivated aquarists with its beauty and intriguing behavior.

In the wild, the Blue-spotted Angelfish inhabits the coral-rich waters of the Western Pacific, where it plays a role in maintaining the health of coral reefs. Its presence in the aquarium trade is limited, often due to its specific habitat requirements and the challenges associated with its collection and transport.

Care

Caring for the Blue-spotted Angelfish requires a commitment to maintaining pristine water conditions and a spacious environment. This species thrives in large, well-established aquariums that mimic its natural reef habitat. A tank of at least 500 liters is recommended to accommodate its active swimming habits and territorial nature.

The aquarium should be equipped with plenty of live rock to provide hiding spots and grazing areas. The Blue-spotted Angelfish appreciates a varied environment with caves and overhangs, which help reduce stress and encourage natural behaviors.

Diet and Feeding

In the wild, the Blue-spotted Angelfish is an omnivore, feeding on a mix of algae, sponges, and small invertebrates. In captivity, it requires a diverse diet to thrive. Offer a combination of high-quality marine pellets, frozen foods such as mysis shrimp and brine shrimp, and fresh seaweed or algae sheets.

Feeding should occur two to three times daily, with portions that can be consumed within a few minutes. This feeding regimen helps maintain their vibrant coloration and overall health.

Behavior and Compatibility

The Blue-spotted Angelfish is known for its semi-aggressive temperament, particularly towards other angelfish and similar species. It is best kept as the only angelfish in a tank to prevent territorial disputes. However, it can coexist with a variety of other reef-safe fish and invertebrates if introduced carefully.

While not considered reef-safe, the Blue-spotted Angelfish may nip at corals and sessile invertebrates, so caution is advised when housing them in reef setups.

Reproduction

Breeding the Blue-spotted Angelfish in captivity is challenging and rarely achieved. They are known to form monogamous pairs in the wild, but replicating the conditions necessary for spawning in an aquarium setting is difficult. Successful breeding requires precise control of water parameters and a large, stress-free environment.

Health and Common Issues

With proper care, the Blue-spotted Angelfish can live for several years in captivity. Maintaining high water quality and a balanced diet is crucial to preventing common health issues such as ich and bacterial infections. Regular observation for signs of stress or illness, such as changes in coloration or behavior, is important for early intervention.

Habitat

The Blue-spotted Angelfish is native to the coral reefs of the Western Pacific, particularly around the Philippines and Indonesia. It prefers warm, clear waters with abundant coral cover and moderate water flow. These conditions should be replicated in captivity to ensure the fish's well-being.
