Japanese Swallowtail Angelfish

The Japanese Swallowtail Angelfish, originating from the coral-rich waters of the Western Pacific Ocean, dwells around coral reefs and rocky areas. Considered reef-safe, it typically coexists peacefully with corals and other reef invertebrates, though individual behavior may vary. With a maximum size of 9 inches and a lifespan of 10 to 15 years, these angelfish thrive on a diet of marine pellets, flake foods, and various frozen offerings.

While not available through aquaculture, they are compatible with peaceful tankmates like clownfish, firefish gobies, royal grammas, purple firefish, and six-line wrasses. Despite a generally peaceful temperament, ensuring adequate hiding spots and space in a minimum 120-gallon tank is crucial to mitigate potential territorial behavior. Additionally, maintaining stable water conditions with a pH of 8.1-8.4, salinity of 1.020-1.025, and moderate water flow ensures their well-being in captivity.

A tank with a capacity of at least 120 gallons is recommended to accommodate their size and swimming behavior.

• pH: Maintain a stable pH level between 8.1 and 8.4.
• Salinity: Keep the salinity in the range of 1.020 to 1.025.
• Water Temperature: Maintain the water temperature within the range of 75-82°F (24-28°C).
• Water Flow: Moderate water flow is suitable to mimic their natural habitat.
