Angel Fish Saltwater - Angelfish

Angel Fish in saltwater tanks are like colorful gems underwater. They are well-known for their bright colors and how they look against a coral reef.

But here’s a surprising thing – these lovely fish are not safe for reefs and need extra care when you put them in a tank with corals. They also need a lot of space to swim happily.

In this article, we’ll talk about saltwater angel fish and share important info about how to take care of them, which ones can live together, and which ones you can add to your tank. Keep reading to know more.

The History of Angelfish

Angelfish come in two types: freshwater fish and saltwater fish. The saltwater ones belong to the Pomacanthidae family, while the freshwater ones, like the popular P. scalare, are part of the Pterophyllum genus in the Cichlidae family.

There are three recognized Pterophyllum species today: P. scalare (the common aquarium angelfish), P. altum, and P. leopoldi.

Freshwater angelfish originally come from Brazil and the lower Amazon region. They live in areas with lots of plants. Their slender bodies help them glide through the vegetation, navigating leaves and branches easily.

Angelfish arrived in Germany in 1909 and were successfully bred in the United States by 1921. Back then, they were pricey, but now they’re some of the most popular aquarium fish.

Over time, people bred beauty angelfish to have different colors. You’ll find varieties like silver (similar to the P. scalare in the wild), zebra, koi, black lace, goldflake angelfish, blushing, marble, golden marble, half-black, and altum (from the less common P. altum species).

Are Saltwater Angelfish Aggressive?

Angelfish are known for their bold personalities and territorial behavior, especially during spawning. They are active during the day but seek shelter in the rock shadows at night of this rock beauty angelfish. In captivity, they can be aggressive, particularly if introduced improperly or placed in a small tank. 

The degree of aggression varies among species and individual fish. Certain types, such as the Emperor angelfish, should be added last to prevent issues with tank mates. It’s crucial to thoroughly research each species before introducing them to your aquarium.

How Long Do Angelfish Live?

Angelfish are known for their resilience, making them easier to care for compared to other fish breeds. Their peaceful nature also means they engage in fewer conflicts than betta fish. With proper care, an angelfish has the potential to live for an impressive 10 to 15 years.

Differences Between Angel Fish Species

Angel Fish Saltwater - Types of Angelfish

As previously mentioned, the Pomacanthidae family encompasses various types of angelfish.

Before delving into the details of specific marine angelfish species, let’s first provide a broad overview of the most commonly encountered genera.


Indian Oceans. In their natural habitat, they form harems led by a dominant male and multiple females.

Examples of species in this genus include the Coral Beauty Angelfish (Centropyge bispinosa) and the Flameback angelfish (Centropyge acanthops).


These majestic angelfish are notably larger fish and include giants like the Emperor angelfish (Pomacanthus imperator). They are distributed across almost all tropical waters globally, with a concentration in the Indo-Pacific and Pacific Ocean.

Pomacanthus members undergo significant physical transformations from their juvenile to adult stages. These changes can be so drastic that juvenile fish might not be recognizable as the same species.

Adult Pomacanthus spp. are highly prized for their vibrant colors and distinctive patterns.

Tank Requirements

Keeping angelfish in your home aquarium can be rewarding, but it’s crucial to create the right environment for them to stay healthy. First, make sure your tank has been running for at least 3 months to establish a stable nitrogen cycle. During this time, do regular water changes to keep ammonia and nitrite levels in check. This sets the stage for your angelfish to have a good start in a healthy saltwater tank.

In addition to a well-established tank and good water quality, there are a few other things to consider for saltwater angelfish. Most of them prefer reef tank environments, and the tank size needed can vary. 

Smaller angelfish or dwarf angelfish might do well in a 50-gallon tank, while medium and larger angelfish ones need 100 gallons or more. Having a spacious tank helps reduce aggressive behavior and increases your chances of successfully keeping angelfish. 

Before getting any angelfish, research the specific species you’re interested in to tailor your tank conditions to their needs. Maintaining the right balance in salinity, pH, temperature, and other aspects of water chemistry is essential for the well-being of your angelfish.

Recommended Species

To keep angelfish happy and healthy in your home tank, it’s best to pick hardier species. These types of angelfish are more likely to eat well in captivity and adjust comfortably to the limited space in a home tank.

  1. Pearlscale Angelfish (Centropyge vrolicki)
  • Recommended for beginners.
  • Not the most colorful, but they only grow to 4 inches and are usually affordable.
  1. Queen Angelfish (Holacanthus ciliaris)
  • Grows up to 18 inches with bright blue and yellow colors.
  • Hardy for beginners but needs a big tank (at least 180 gallons).
  • Fairly aggressive, so be cautious about tank mates.
  • Requires multiple small feedings a day, eating sponges, jellyfish, and phytoplankton.
  1. Emperor Angelfish (Pomacanthus imperator)
  • Exotic with blue and yellow colors, horizontal stripes, and a black band across the eyes.
  • Grows up to 12 inches in captivity.
  • Moderately hardy and a bit tricky to care for.
  • Semi-aggressive by nature.
  • Requires a diet rich in sponge, spirulina algae, brine shrimp, and mysis shrimp.
  • Suitable for aquariums 125 gallons and larger.
  1. Yellow Tail Angelfish (Apolemichthys xanthurus)
  • Also known as Xanthurus Cream Angelfish.
  • Easy to care for but very aggressive.
  • Grows up to 8 inches and needs at least 125 gallons.
  • Cream-colored body with a black nox angelfish outline and a yellow caudal fin.
  • Tends to nip at coral reefs, so be cautious in a reef tank.
  1. French Angelfish (Pomacanthus paru)
  • Dark gray angelfish overall with gold-tipped scales.
  • Hardy and suitable for beginners.
  • Requires a very large tank (at least 180 gallons, ideally 250 gallons).
  • Grows up to 16 inches and can live for 15 years or longer.
  • Omnivorous, preferring foods with sponge and spirulina algae.
  1. Blue Angelfish (Pomacanthus xanthometopon)
  • Named for its blue face, with a blue body and yellow tipping on the scales.
  • Requires moderate care and is semi-aggressive.
  • Grows up to 15 inches and needs a large tank (at least 220 gallons).
  • Grazes on live rock and needs a diet supplemented with spirulina, shrimp, and other meaty foods.

Other species like Fisher’s angels, Ornate angels, King angels, Six bar angels, and blue-faced angels can also be considered, but they may be a bit less hardy. If you can maintain stable water conditions, they might still be a good choice.

Feeding Your Angelfish

Angel Fish Saltwater - Feeding Your Angelfish

To keep your angelfish happy and healthy, it’s essential to give them the right food. Choose Tropical Granules or Tropical Flakes for your friendly tropical fish. They’ll also enjoy treats like bloodworms or brine shrimp every now and then.

Remember, don’t feed your angelfish too much. Once or twice a day is plenty, usually in the morning and evening. Only give them what they can eat in about two to three minutes. Signs of overfeeding include uneaten food after five minutes, cloudy water, or a clogged filter.

Breeding Angelfish

Breeding angelfish is quite simple, and they might even pair up on their own. If you want baby angelfish (called fry), it can be tricky to tell males from females. Some males have a bump on their heads, but not always. You can buy a few young fish and see which ones pair off as they grow.

Females lay eggs in vertical lines, and the male fertilizes them afterwards. They prefer laying eggs on broad, vertical surfaces like plants with broad leaves or a vertical pipe. Amazon sword plants work well for laying eggs.

Both the male and female care for the eggs, protecting and fanning them to keep them clean and oxygenated. They can be so protective that they might attack other angelfish tankmates during breeding. After a few days, the eggs hatch, and the fry stays attached to the surface, eating the yolk. They start swimming in about a week and might enjoy tiny, newly hatched brine shrimp, available at pet stores.

Some people move a breeding pair to a separate tank before they lay eggs to prevent other fish from eating them. This tank should be around 20 gallons with a slanted, flat surface for laying eggs and a gentle sponge filter that won’t harm the babies. After about six weeks, the baby fish can return to the main tank if it’s big enough.

Taking Care of Your Angel Fish

Just like any pet, angelfish can get sick. If you think your fish is not feeling well, try to find a fish doctor (a veterinarian who takes care of fish) in your area. If you can’t find one, talk to the person who owns the aquarium store for advice or to find a fish expert. You want someone who knows a lot about fish to help figure out what’s wrong and the best way to make your fish feel better.

Watch out for signs that your fish might be sick, like:

  • Holes in the fish’s temples
  • White spots
  • Scales sticking out or eyes sticking out
  • Being very slow or not moving much
  • Fin rot (when the fins look damaged)

Many fish illnesses can be fixed with good care. If your fish does get sick, it’s a good idea to keep them away from the other fish in a separate tank while they get better with the help of the fish doctor or expert. The good news is that angelfish are strong, so if you clean the tank and change the water regularly, they should stay healthy and happy.

Choosing the Right Tank Mates

Angel Fish Saltwater - Angelfish Tank Mates

When you decide to have angelfish in your home tank, it’s important to pick species that are likely to do well in captivity. While most fish can get used to living in a tank, some angelfish, like bicolor angelfish species find it harder to adapt. Examples include Hawaiian bandit angelfish, Barred angelfish, Regal angelfish, and Oriole angelfish.

The challenge with these species is that they might not adjust to eating in a tank. While many saltwater fish will eat different types of food, these angelfish might not eat anything in captivity. Some of them are also more likely to get sick, like the Barred angelfish, making it tough to keep them healthy. Even if they seem fine for a few weeks, they might actually be slowly getting weaker. For instance, less than half of Oriole angelfish in tanks survive beyond 6 months.

Taking care of angel fish saltwater can be very satisfying. You’ll see your beautiful fish grow and be happy because of your care. Setting up the tank and making everything ready might take a bit of time, but it’s totally worth it when you see your fish living its best life.
