The Bellus Angelfish (Pomacanthus Bellus) is a species of marine ray-finned fish, a marine angelfish belonging to the family Pomacanthidae. This species occurs in the Indo-West Pacific region.

This is a beautiful species that is very popular in the aquarium trade. It is one of the smaller members of its genus. The Bellus Angelfish has a body that is deep and compressed.

They add plenty of verticality and interest to the reef aquarium. And, their small size means they fit into reef aquariums of just about any size.

Captive-bred specimens are readily available and make much better aquarium fish than wild-caught individuals.

This article will provide detailed information on everything you need to know about caring for Bellus Angelfish in the home aquarium.

The Bellus Angelfish, also known as the Ornate Angelfish or the Bellus Lyretail Angelfish, is a marine ray-finned fish part of the family Pomacanthidae. This family contains the marine angelfish.

Bellus Angelfish Species Summary

They aren't commonly sold in the fish trade, but they are a beautiful species that is very popular in the aquarium trade. The price for a juvenile Bellus Angelfish can range from $30-$50, but the price for an adult is usually around $100.

Bellus Angelfish Appearance

The Bellus Angelfish is a beautiful fish with a deep and compressed body. Their coloration is orange-yellow with vertical blue stripes.

Bellus Angelfish Appearance

The fins are all blue, except for the pectoral fins, which are clear. The males and females look very similar, but the males tend to be slightly larger.

Males have an orange dorsal fin with a blue margin, while females have a yellow dorsal fin with a blue margin.

The Bellus Angelfish is sometimes confused with the Koran Angelfish (Pomacanthus semicircular) but can be distinguished by having more vertical blue stripes. Their caudal peduncle does not have any spots. Both sexes have a lyretail, but the males are much more pronounced.

An adult Bellus Angelfish will have a more confident and relaxed personality than a juvenile. They are also more likely to show their true colors when fully grown.

Bellus Angelfish Size & Growth Rate

The Bellus Angelfish is one of the smaller members of its genus. They grow to a maximum length of around 7 inches, but they are more commonly seen at a size of 4-5 inches.

Bellus Angelfish Size & Growth Rate

However, they have been reported to grow up to 12 inches in the wild.

Bellus Angelfish Lifespan

A healthy fish kept in proper conditions has the potential to live for 10 years or more.

Therefore, a Bellus Angelfish's lifespan is relatively long compared to similar fish species.

Bellus Angelfish Behavior & Temperament

Bellus Angelfish are social and peaceful fish. They can be kept with other delicate fish of a similar size. They are not suitable for a reef tank due to their potential to nip at corals and invertebrates. 

Bellus Angelfish Behavior & Temperament

They enjoy being in a small group and do best when kept in a group of 5 or more. The males can be territorial, so it is best to keep 1 male per 3 to 4 females.

However, males will fight with each other if there are not enough females. The males tend to be more aggressive than the females.

They are not suitable for a community tank unless it is a huge tank and has plenty of hiding places. They are shy fish and will spend most of their time hiding if they feel threatened. It is essential to provide them with plenty of hiding places in their tank.

Breeding

Bellus Angelfish are challenging to breed in captivity. They are protogynous hermaphrodites, which means that they all start as females and then turn into males. The males are much larger than the females and have longer fins.

You will need a large tank with plenty of hiding places to breed them successfully. It is best to keep 1 male per 3-4 females. The males will be very aggressive with each other if there are not enough females.

The female will lay her eggs on a flat surface such as a rock or piece of coral. The male will then fertilize the eggs. After the eggs have been fertilized, the female will pick them up and keep them in her mouth until they hatch.

This process can take anywhere from 2-4 weeks. Once the eggs have hatched, the fry will be released into the water. They will need to be fed minimal food items such as brine shrimp or micro worms.

It is essential to provide plenty of hiding places for the fry as they will be vulnerable to predation.

The fry will proliferate and reach adulthood within 6-8 months.

After the fry has reached adulthood, it can be difficult to have sex. The best way to sex them is to look at their fins. The males will have much more extended fins than the females.

The easiest way to breed them is to buy a group of juveniles and allow them to grow up together. Eventually, they will reach maturity and start producing on their own.

Bellus Angelfish Care

Caring for these fish is not difficult, but it is important to note that they are semi-aggressive. They should only be kept with peaceful fish that are not similar in appearance.

Bellus Angelfish Care

They are also known to compete for food with other angelfish, so it is best to keep them well fed.

Setting up a suitable tank is essential for the long-term health of your Bellus Angelfish. It is necessary to provide hiding places and plenty of live rock for them to graze on. Test the water quality regularly and do not hesitate to change the water if necessary.

There aren't any specific diseases that target them, but they are susceptible to the same illnesses that affect all marine fish.

Here are some tips to help you keep your Bellus Angelfish healthy:

Tank Size

The minimum tank size for a Bellus Angelfish is 120 gallons, but a larger tank is always better. They are active swimmers and need plenty of space to move around.

However, they are relatively slow eaters, so a smaller tank can be suitable if not too many other fish are present.

When setting up your tank, use a quality filter and provide plenty of live rock for them to graze on.

Water Parameters

They are native to reefs in the Indo-Pacific region, so they are used to warm water. The ideal temperature range for them is between 72°-76°F.

They also prefer a pH level of 8.1-8.4 and a water hardness of 8-10 dGH. It is essential to test the water quality regularly and make changes as necessary to maintain these parameters.

New fish owners should take care when adding these fish to their tank as they are sensitive to sudden changes in water conditions.

Filtration

When choosing a filter for your Bellus Angelfish, make sure to get one suitable for your tank's size. A good rule of thumb is to get a filter that can turn over the entire volume of your tank at least once per hour.

They are not particularly messy eaters, but they produce a moderate amount of waste. Therefore, a quality protein skimmer is also recommended.

Some recommended filters for their tank include the following:

  • Fluval FX6 Canister Filter: This filter is suitable for tanks up to 400 gallons and has a flow rate of 630 GPH. This makes it a good choice for their tank.
  • AquaClear 110 Hang-On Filter: This filter is suitable for tanks up to 100 gallons and has a flow rate of 500 GPH. This makes it a good choice for a smaller Bellus Angelfish tank.

Protein Skimmer

A protein skimmer is not essential, but it is recommended to help keep the water quality high. A good protein skimmer will remove waste and other contaminants from the water before they have a chance to build up.

Some recommended protein skimmers for a Bellus Angelfish tank include the following:

  • AquaC EV-180 Protein skimmer: This protein skimmer is suitable for tanks up to 200 gallons and has a flow rate of 500 GPH. This makes it a good choice for their tank.
  • AquaC EV-240 Protein skimmer: This protein skimmer is suitable for tanks up to 400 gallons and has a flow rate of 1000 GPH. This makes it a good choice for a larger Bellus Angelfish tank.

Heating

They are native to warm water, so providing a heater in their tank is essential. The ideal temperature range for them is between 72°-76°F.

Some recommended heaters for their tank include the following:

  • Eheim Jager Aquarium Heater: This heater is suitable for tanks up to 60 gallons and has a temperature range of 68°-88°F. This makes it a good choice for a smaller Bellus Angelfish tank.
