Blueface angelfish are large-sized fish that can grow up to 15 inches in length. Their body is predominantly yellow with vibrant blue face, which gives them their name. The dorsal fin is also blue, and the anal and pelvic fins are yellow. The coloration of Blueface angelfish changes as they mature, with the juvenile fish having a more subdued coloration. The adults have vibrant blue face, which is surrounded by a bright yellow ring.


The natural habitat of Blueface angelfish is the tropical waters of the Western Pacific Ocean, from the Ryukyu Islands of Japan to the Great Barrier Reef of Australia. These fish are found in coral reefs, where they can hide and seek shelter among the crevices and coral heads. They are often found in the deeper areas of the reef, at depths ranging from 15 to 150 feet.


Blueface angelfish are active swimmers that are generally peaceful towards other fish. However, they can become territorial when they reach adulthood, especially towards other Blueface angelfish of the same sex. These fish are known to form mating pairs, and they are monogamous, staying with their partner throughout their life. Blueface angelfish are omnivores, and in their natural habitat, they feed on a variety of plankton, algae, and small invertebrates.

Care requirements:

Blueface angelfish are not recommended for beginner aquarists due to their size and specific care requirements. These fish need a large tank that can accommodate their swimming needs. A tank with a capacity of at least 100 gallons is required for a single adult Blueface angelfish, and additional space is needed for a breeding pair. The tank should have plenty of live rock, which will provide hiding places for the fish, and help to maintain the water quality. The water should be kept at a temperature of 72 to 78 degrees Fahrenheit, with a pH between 8.1 and 8.4. A high-quality protein-rich diet is essential for the fish’s health, and they should be fed small amounts of food multiple times a day.

Aquarium requirements:

Blueface angelfish are stunning marine fish that require a specific environment to thrive in an aquarium. Here are the aquarium requirements that you need to consider if you are planning to keep Blueface angelfish:

  1. Tank Size: Blueface angelfish can grow up to 15 inches in size, which means they require a large aquarium. A minimum tank size of 100 gallons is recommended for a single Blueface angelfish, and if you plan to keep a breeding pair, a tank of at least 150 gallons is required.
  2. Water Quality: Blueface angelfish require high-quality water conditions. The pH should be maintained between 8.1 to 8.4, and the temperature should be kept between 72°F to 78°F. The salinity level should be between 1.023 and 1.025, and the water should be well-oxygenated. It is important to perform regular water changes and test the water parameters frequently.
  3. Filtration: Blueface angelfish produce a lot of waste, so a robust filtration system is necessary. A protein skimmer is recommended to remove organic waste from the water. Live rock can also help to maintain the water quality and provide hiding places for the fish.
  4. Lighting: Blueface angelfish require moderate lighting in the aquarium. It is best to mimic their natural habitat, so a light spectrum of 10,000K to 20,000K is ideal.
  5. Substrate and Decor: Blueface angelfish prefer an aquarium with live rock and sand substrate. The live rock provides hiding places and territories for the fish. It is important to provide enough space for swimming and hiding, as Blueface angelfish can become territorial.
  6. Diet: Blueface angelfish are omnivores and require a varied diet to stay healthy. They can be fed a mix of high-quality flake, pellet, and frozen foods, including meaty foods like shrimp and krill. It is important to feed them several small meals throughout the day.
  7. Tank Mates: Blueface angelfish can be kept with other non-aggressive marine fish. Avoid keeping them with other angelfish, as they can become aggressive towards their own species.

In summary, Blueface angelfish require a large aquarium with high-quality water conditions, robust filtration, moderate lighting, live rock and sand substrate, and a varied diet. Proper care and maintenance are crucial for the health and well-being of Blueface angelfish. If you are considering keeping these fish, be sure to research their specific needs and consult with a knowledgeable professional.


Are Blueface Angelfish reefss safe?

No, Blueface Angelfish are not considered reef safe due to their tendency to nip at soft and stony corals, as well as invertebrates such as clams, anemones, and shrimp. They are best kept in fish-only or fish-only-with-live-rock (FOWLR) aquariums with non-aggressive tank mates. It is important to monitor their behavior closely and be prepared to remove them from the aquarium if they show signs of aggression toward other tank inhabitants.

How big do Blueface Angelfish get?

Blueface Angelfish can grow up to 15 inches (38 cm) in length and 10 inches (25 cm) in height. It’s important to provide them with a large enough aquarium to accommodate their size as they grow, as well as plenty of hiding places and live rock for territorial behavior. The minimum tank size for a single Blueface Angelfish is around 125 gallons, and larger tanks are recommended for pairs or groups. Proper nutrition, water quality, and regular maintenance are also important factors for their growth and overall health.

How long do Blueface Angelfish live?

Blueface Angelfish have an average lifespan of 7-10 years in captivity, although some specimens may live longer with proper care and a suitable environment. Factors that can affect their lifespan include water quality, diet, tank size, and overall health. It’s important to provide them with a well-maintained aquarium, appropriate nutrition, and regular health checks to help ensure a long and healthy life.


In conclusion, the Blueface angelfish is a beautiful fish that can make a great addition to a large marine aquarium. They are relatively easy to care for, but they require a tank with ample space, and specific water parameters should be maintained. Their striking blue and yellow coloration makes them a favorite among fish-keeping enthusiasts, and their active personalities can provide endless hours of entertainment.
