Diet: Flagfin Angelfish are omnivores and thrive on a varied diet. They do well on a mix of high-quality flake food, pellets, and frozen foods such as brine shrimp and mysis shrimp. Including marine algae or spirulina in their diet helps maintain their health and vibrant coloration. Providing a varied diet helps maintain their health and vibrant coloration.

Tankmates: Flagfin Angelfish can be somewhat territorial and should be housed with other robust and similarly sized fish. Suitable tankmates include larger tangs, angelfish, wrasses, and groupers. This fish can be kept with other angelfish of the same genus. It is advisable to introduce them all at the same time to an appropriately sized aquarium, usually 5 feet or longer.

Max Size: Flagfin Angelfish can grow up to 10 inches (25 cm) in length. Due to their size and active nature, they require a spacious aquarium of at least 125 gallons to thrive and maintain good water quality.

Origin: Flagfin Angelfish are commonly found in the Indo-Pacific region, particularly around the waters of the Great Barrier Reef, Indonesia, and the Philippines.
