The Pygmy Angelfish is a reef-dwelling fish that prefers to live in areas with plenty of hiding places. These fish live in coral reefs and lagoons in the wild. It is essential to provide plenty of hiding places and live rocks for your Pygmy Angelfish to feel comfortable in the home aquarium.

Cuvier first described them in 1831 by the French naturalist Georges Cuvier from specimens collected in the West Indies. The Pygmy Angelfish is one of the most popular saltwater aquarium fish. They are brightly colored and have a unique pattern that makes them stand out in any aquarium.

The cost of a Pygmy Angelfish can vary depending on the size and color of the fish. They are typically priced between $10 and $20.

Pygmy Angelfish Appearance

The Pygmy Angelfish is a brightly colored fish that has a unique pattern. They are typically orange or yellow with blue stripes. Some species can also be found in shades of green and brown. The fins of a Pygmy Angelfish are usually orange or yellow.

Like other dwarf Angelfish, the Pygmy Angelfish has a small mouth and a long snout. They also have a large dorsal fin and pectoral fins. And these fish are also known for their bright blue eyes.

Pygmy Angelfish Appearance

They resemble mini versions of larger angelfish species, making them popular for saltwater aquariums. And because of their smaller size, they are also a good choice for nano aquariums.

You can enjoy the look and color of the Pygmy Angelfish without having to worry about them getting too big for your aquarium.

Pygmy Angelfish Size & Growth Rate

The size of a Pygmy Angelfish can vary depending on the species. The average size is 3 inches. Some species can grow up to 5 inches.

The growth rate is relatively slow. They typically grow 1/2 to 1 inch per year.

Pygmy Angelfish Lifespan

The lifespan of a Pygmy Angelfish is 5 years, and in some cases, they have been known to live up to 10 years.

However, it is essential to note that the water quality in their environment can significantly affect their lifespan. Poor water quality can lead to health problems and shorten the lifespan of your fish.

Pygmy Angelfish Breeding

They are challenging to breed in captivity. They are known to be shy and secretive when it comes to spawning. In the wild, they typically spawn in pairs or small groups.

To increase your chances of success, it is best to keep a group of at least 5-6 fish and allow them to choose their mates. The chosen pair will then separate themselves from the group and clean a small area of the tank where they will lay their eggs.

Pygmy Angelfish Breeding

The female will lay up to 500 eggs which the male will fertilize. The eggs will hatch in 24-48 hours, and the fry will be free-swimming a few days later.

The fry is tiny and will need to be fed microscopic food such as baby brine shrimp or rotifers. They can also be fed commercially available fry food.

Pygmy Angelfish are not easy to breed in captivity, and success is not guaranteed. However, it can be a rewarding experience if you can breed them successfully.

Pygmy Angelfish Behavior & Temperament

They are feisty creatures that can be aggressive towards other fish, especially those similar in size and shape. They are also known to nip at the fins of other fish.

Because of their aggression, keeping them with other peaceful fish that are too large to be seen as potential prey is best. I recommend no more than one male per tank, as they will fight each other for dominance.

They are not recommended for reef tanks as they may pick at or eat small invertebrates. However, achieving this balance is not always possible, and many people have had great success keeping pygmy angels in reef tanks.

One way that you can reduce aggression is by keeping your fish well-fed. A well-fed fish is less likely to be aggressive than a hungry fish. You can also provide them with plenty of hiding places so that they feel secure and less likely to attack other fish.

This extra space will also help reduce aggression, as fish that are too close together are more likely to attack each other.

Pygmy Angelfish are intelligent and exciting fish to watch. They are known to be curious and often approach divers and swimmers in the wild. They may follow you around the tank and beg for food in captivity. They are active fish that enjoy swimming in all areas of the tank.

Pygmy Angelfish Care

The Pygmy Angelfish is a relatively easy fish to care for. They are hardy and can tolerate a wide range of water conditions. However, good water quality is essential to ensure their health and longevity.

In the wild, they live in coral reefs and lagoons. Providing plenty of hiding places and live rocks is essential to feel comfortable in the home aquarium.

Pygmy Angelfish Care

It is a peaceful fish that gets along well with other fish. However, they can be aggressive towards other dwarf Angelfish. It is best to keep them with fish that are larger than them.

It is an Omnivorous fish that feeds on small invertebrates in the wild. Providing them with a varied diet is essential to ensure their health. You can also supplement your diet with live foods.

We will review everything you need about caring, including their diet, tank requirements, water parameters, and joint health problems.

Pygmy Angelfish Tank Size

The minimum tank size for a Pygmy Angelfish is 55 gallons. However, it is best to provide them with a larger tank if possible. An 80-gallon tank is a good size for one or two.

However, if you plan on keeping more than two, providing them with a larger tank is best. A 120-gallon tank is a good size for a group.

Providing plenty of hiding places and live rocks is essential when setting up your tank. They will also appreciate a sandy substrate.

Pygmy Angelfish Water Parameters

You can give live, frozen, or freeze-dried foods. It is essential to offer various foods to ensure your fish get all the necessary nutrients.

They will exist on marine algae for much of their diet and accept meaty items and live foods.

Flakes, pellets, or granules are not accepted unless they contain high marine algae or Spirulina levels.

Pygmy Angelfish Diet Foods To Avoid

There are some foods that you should avoid feeding.

Some of these foods include:

  • Bread
  • Cookies

These foods are high in sugar and fat and can cause health problems for your fish.

Pygmy Angelfish Feeding Schedule

Your Angel will enjoy eating from the same place each day and should be given food 2-3 times daily in small amounts that can be consumed within 5 minutes.

Overfeeding should be avoided as uneaten food will sink to the substrate and decompose, polluting the water and potentially leading to disease.

It is best to target feed your Angel so you can be sure it is getting enough to eat without overfeeding the tank. This can be done using a pipette or a small syringe to target the food toward your fish.

Also, offer various foods to ensure your Angel gets all the nutrients it needs.

Pygmy Angelfish Tank Mates

Avoid peaceful, calm, and slow-moving fish, as they will likely be seen as potential prey. I also recommend avoiding fish similar in size and shape to pygmy angels, as they may be mistaken for rivals and attacked.

Some good tank mates for pygmy angels include:

While most of these fish are peaceful, some (like tangs and dotty backs) can be aggressive toward other fish. Be sure to do your research before adding any fish to your tank.
