Keeping Japanese Swallowtail Angelfish in an aquarium requires the right conditions.

Aquarium Information

  • Care level: intermediate
  • Temperament: peaceful
  • Diet: omnivore
  • Minimum tank size: 120 gallons
  • Compatibility: Generally compatible with most peaceful to semi-aggressive reef-safe fish. Avoid very aggressive tank mates or those that might outcompete it for food. Can be kept in pairs or a harem (one male with multiple females) in sufficiently large aquariums.
  • Special requirements: Requires a well-established aquarium with plenty of live rock for hiding and grazing. Good water quality and stable parameters are crucial. Provide a varied diet including high-quality marine flakes, pellets, frozen mysis shrimp, brine shrimp, and spirulina-based foods. They are prone to stress if housed in too small an environment or with overly aggressive tank mates.
