Care

Caring for the Blue-spotted Angelfish requires a well-established aquarium with plenty of live rock for grazing and hiding. This species can grow up to 18 centimeters (7 inches) in length, so a larger tank is necessary to accommodate its size and swimming needs. They are omnivores, feeding on a variety of foods including algae, sponges, and meaty foods. It's important to provide a varied diet to ensure proper nutrition and health.

Reproduction

In the wild, Blue-spotted Angelfish are known to form harems consisting of one male and several females. They are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. In the home aquarium, breeding is rare, but with optimal conditions and a well-matched pair, spawning behavior may be observed.

Habitat

The Blue-spotted Angelfish is native to the Western Pacific Ocean, particularly around Japan, Korea, and Taiwan. They are typically found in subtropical reef environments, often in areas with strong currents and rich coral growth. In the wild, they are usually seen at depths ranging from 5 to 30 meters (16 to 98 feet).
