Marine Angelfish( Blueface angelfish) Characteristics

Blueface Angelfish Origins and Distribution

The Blueface angelfish or the Yellowface angelfish is a marine angelfish from the family Pomacanthidae, found in shallow parts of the Indo-Pacific.

Pomacanthus xanthometopon can also be found in the Maldives Islands, Malaysia, Indonesia, Japan, Taiwan, the Philippines, northern Australia, and Micronesia.

Pomacanthus xanthometopon is frequently seen among rocks and near caves at depths of 25 to 75 meters (82 to 246 feet). The youngsters are commonly seen living inside caverns.

Blueface Angelfish Lifespan

The average lifespan is 15 – 25 years (provided that it is looked after properly). blueface angelfish can live longer in aquariums.

The Blueface angelfish grow to a maximum length of 38 centimeters (15 in) and is laterally compressed.

The mouth is positioned just above the snout’s tip, while the fins are large and rounded, with yellow edges bordered in blue.

The rear fin is located just in front of the tail, has a distinct black eyespot at its base, and has 13–14 spines and 16–18 soft rays.

The anal fin, on the other hand, has three spines and 16–18 soft rays. The scales are pale yellow with blue borders, creating a reticulated pattern.

There are brilliant blue lines on the bottom half of the yellow face and a simple yellow mask around the eyes.

The juvenile hue is different from that of the adults, with six vertical white bars separated by pale blue lines and a dorsal fin barred in two shades of blue.

The coloration of the juveniles gradually changes after blueface angelfish reach a length of 7 to 12 centimeters (2.8 to 4.7 inches).

The queen angelfish (Holacanthus ciliaris) or blue angelfish (Holacanthus bermudensis) can be mistaken for this species, but both have a completely blue face and lack the caudal eyespot.

Blueface Angelfish Health and Care

The Blueface angelfish, like other saltwater angelfish, demands specialized maintenance and upkeep of water quality to survive.

Also, like other saltwater angelfish species, this saltwater fish is susceptible to disease and sickness, especially when startled.

As a result, there are some things you should keep in mind:

1. Proper Tank Size

These species will be comfortable in such a large tank with plenty of places to hide and swim.

So, a tank that is 125 gallons for juveniles and 225 to 275 gallons for adults is sufficient.

2. Water Parameters

PH Level

A healthy water condition should have a hardness of 8 to 12 dKH and a pH of 8.1 to 8.4.

However, captive specimens thrive in somewhat more acid conditions, especially if marine angelfish come from areas where the environment is reasonably neutral.

Raise your pH by one point if a member of your tank begins to display indications of stress, such as lethargy or clamped fins.

As Blueface angelfish are hardy fish that can be raised in captivity, it’s vital not to overwork them based on their natural habitat.


Blueface Angelfish comes from tropical waters so keeping the temperature at a steady 78 to 82 degrees Fahrenheit.

Specific Gravity

The specific gravity for these fish should be between 1.023and 1.025.

Ammonia, Nitrite, and Nitrate Levels

Ammonia, nitrite, and nitrate are extremely harmful to marine angelfish life, so keeping them all at 0 ppm is essential for a healthy tank.

3. Water Change Frequency

Bluefaced angelfish isn’t adaptable to shifting water conditions, so, you’ll need to be meticulous about testing the water and performing regular water changes.

The most frequent amount for changing is 15% every other week or 39% every month.

4. Filtration

Filters are critical because blueface angelfish remove waste and toxins from the water, making it healthy for your saltwater fish.

A liter of saltwater can produce up to .5 grams of ammonia a day, so be sure to have a quality filter system in place.

We recommend using a canister filter rated for an aquarium of 300 gallons or more.

5. Tank Decoration

Blueface angelfish love to hide, so be sure to have plenty of caves, overhangs, and places to explore.

Live rock is ideal for this as it provides both hiding spots and a natural food source.

Blueface Angelfish Diet

The Blueface angelfish are primarily omnivores with an appetite for high-fat food. These modest eaters will consume nearly anything you give them.

Here are some examples of algae- and meat-based diets:

  • Spirulina
  • Marine algae
  • High-quality angelfish preparations
  • Mysis
  • Frozen shrimp
  • Silversides
  • Krill

Also, frozen food is acceptable, but try to add fresh ingredients daily for your Blueface angelfish

Blueface angelfish also require a lot of live bacteria in their digestive system to maintain their health.

Further, adding vitamin C-rich foods like Nori seaweed or shredded carrots to your aquarium might assist your fish fight off stress-related illnesses.

Keep in mind that these fish require tiny portions two to three times a day.

Blueface Angelfish Tankmates & Predators

The Bluefaced Angelfish is slightly aggressive when introduced to an aquarium for the first time. However, as pomacanthus xanthometopon gets more used to its new surroundings, pomacanthus xanthometopon will become bolder.

pomacanthus xanthometopon is less combative than other Pomacanthus species and may harass smaller fish like gobies, clownfish, and blennies in a cramped tank.

Also, pomacanthus xanthometopon cannot be kept with the same species and may harass other small angelfishes if the aquarium is too crowded.

The Blueface Angelfish is a territorial fish that does not tolerate other angelfish and will become aggressive in the presence of one.

larger aquarium fish may pick out slower-moving sharks and stingrays, particularly their eyes.

So, it should be the last fish you put into the tank because of its protective nature.


  • Anemones
  • Large butterflyfish
  • Hawkfishes
  • Puffers

These fish will also consume other aquarium fish that are of comparable size.

Breeding Blueface Angelfish

Although blueface angelfish may be tough to breed, Blueface Angelfish has been developed in captivity with perseverance and care.

Because Blueface angelfish will hybridize with other sorts of Pomacanthus angels, it is advised that only one species be maintained at a time.

This is especially true when housing multiple males, as numerous males will result in frequent fighting for power, which can easily lead to injury or death of smaller fish or lesser individuals.

Furthermore, keeping appropriate water conditions is fundamental for breeding success.

The water conditions that mimic those found naturally as closely as possible and those provided by an air stone or an external power filter should be maintained.

It’s also essential to alter your fish’s diet as blueface angelfish are spawning from high-quality prepared foods to live brine shrimp nauplii, copepods, and Mysis shrimp.

If the female is prepared to spawn, she might begin digging nests approximately two weeks after mating.

It might take a long time to find the best option, so it’s vital not to inconvenience her while she builds her nest.

But if you must move them into a new container, use a bucket rather than your hands because this lessens stress on both parent and fry.

After it has excavated its nest, mating will be the only development for quite some time.

When both parents are present and ready, blueface angelfish will alternate guarding the entrance of their selected chamber while waiting for their partner to fill it with eggs.

If everything goes according to plan, the eggs should be fertilized within 1 to 2 days, after which the incubated eggs will take anywhere from 4 to 6 days.

When the fertilized eggs hatch, blueface angelfish will swim down into deeper water and develop for 8 to 12 months before returning to shallower waters near coral reefs, reaching adulthood at three years old.
