Physical Appearance

The Regal Angelfish is among the most captivating and attractive species among marine angels. It is adorned with vibrant colors. Their coloration varies based on their origin and we will discuss their habitat-specified color later in this article in the habitat section of Regal Angelfish.

An adult Regal Angelfish usually reaches about a medium-sized fish, measuring approximately 8-12 inches in length.

Regal Angelfish Habitat

Regal angelfish was first formally described by Boddaert in his book Elenchus Animalium, where he gave it the name Chaetodon Diacanthus. The Great Barrier Reef, the Tuamoto Islands, and the Ogasawara Islands serve as their habitats, where the warm waters of the Pacific and Indian oceans are the two major habitats of the Regal Angelfish. Their color variations occur from place to place.

The fish can find shelter and food in the diverse coral-rich settings that make up its natural habitat. The species can be found in depths of up to 45 meters and is frequently linked to reef formations.

Now let me explain to you the two major variants of Regal Angelfish depending on their habitat i.e. The Indian Ocean Species and The Indo Pacific Species

Indian Ocean Species

The coral reefs of the Andaman Sea, Comoros, and the Maldives are home to the majestic angelfish in the Indian Ocean. These areas offer a variety of marine life and an abundance of coral formations, which make them the perfect habitat for angelfish. 

Regal Angelfish from the Indian Ocean, including the Red Sea, are highly esteemed for their vibrant coloration. The breast and head coloration of these fish from the Indian Ocean is a striking yellow.

The Indo-Pacific Species

The Great Barrier Reef in Australia, Fiji, and Indonesian waters are home to the Regal Angelfish over the vast waters of the Indo-Pacific region. This species’ distribution throughout the Indo-Pacific area can be attributed to its adaptation to a variety of reef environments.

On the other hand, Regal Angelfish from the Pacific Ocean typically have a blue/gray colored breast and head.

Growth Rate

The growth rate of the royal angelfish is one of its key characteristics. Like many other marine creatures, regal angelfish go through several stages of growth. Understanding the size of an adult regal angelfish helps you to develop an appropriate tank arrangement.

The size of the angelfish varies under its developmental stage.  They grow very quickly as juveniles, according to the environment, and reach lengths of 2 to 3 inches. Those tiny baby angelfish need to be fed correctly during this time to stay healthy.

Their physical growth rate slows down as they get older, and they eventually reach their typical size of 6 to 8 inches.

The maximum approached size that an adult royal empress angel can attain is about 9 to 12 inches (22-30 cm). 

Pro Tip: A large aquarium is always recommended to accommodate their size and let them swim freely without feeling confined.

The larger the tank, the more comfortable it is for these stunning fish to explore and exhibit their natural attributes.

  1. Temperature 

These graceful aquatic creatures like their water to be just the perfect temperature—neither hot nor cold. Thus, try to regulate the temperature of the water between 72°F and 78°F (22°C and 26°C) to ensure their wellness and comfort.

Consider it like adjusting your room’s temperature to the ideal level—neither too hot nor too cold.

regal angelfish are highly sensitive to temperature fluctuations, their aquatic habitat functions as a thermostat.  To ensure that the temperature is exactly perfect, use the aquarium heaters of high quality. The angelfish prefer the water to be warm and stable, this device helps to maintain the temperature according to their habitat.

  1. Lighting 

Providing the ideal lighting for your aquarium is like establishing a pleasant environment for your Regal Angelfish. These fascinating fish, which have vivid colors, feel comfortable being in a bright setting that resembles their natural home. Not only does good lighting look good, but it also gives the angelfish an impression of security and comfort.

Pick lighting options for your aquarium that closely resemble the cycle of natural sunlight. Like many other fish, royal angelfish profit by having a consistent day-and-night cycle. LED lights for aquariums are a good option because they emit a soft, customizable light that is pleasant.

Note: Avoid making it very bright, since this may cause them to become irritated.

  1. PH

To make sure that your Regal Angelfish live in a quiet and pH-friendly underwater environment, keep an eye on the pH levels. PH indicates how basic or acidic the water is. Angelfish prefer their aquatic environment to have a specific pH. The ideal 

pH range for regal angelfish is between 8.1 and 8.4; this is where they thrive.

It’s like keeping their submerged home stable and comfortable, as changes in pH can lead to anxiety and have an effect on their health. To monitor the levels in your aquarium regularly, you can use pH testing kits. To maintain ideal water conditions, you can use pH buffers to make adjustments as needed.

  1. Filtration 

Filtration is the process used to make sure the water is clear of pollutants and undesired particles, giving your angelfish a spotless environment.

Every type of filter—sponge, canister, or hang-on-back—is essential to preserving the purity of the water. These filters eliminate waste and maintain ideal water parameters. To keep the filtration system effective and reliable, regular maintenance includes cleaning or replacing the filter media. Hence, by implementing a dependable filtration system, you’re giving your Regal Angelfish an enjoyable and healthy lifestyle in addition to keeping the water clean.

  1. Hiding Places

Making appropriate hiding spots in the aquarium is important for the health and happiness of the Regal Angelfish and goes beyond simple decor. These hiding spots are very important when Regal Angelfish are stressed out or just need to take a break from their environment. Consider these hiding places for your aquatic friends to be warm shelters or hidden escapes. These tiny corners are similar to giving your angelfish a private area where they may feel secure, relaxed, and in charge of their underwater kingdom.

Appropriate places for concealment offer a peaceful atmosphere, encourage natural activities, and lessen stress.

Royal angelfish is an omnivore. Initially, it shows reluctance to eat anything but ultimately develops eating habits. It relies primarily on the organisms within its habitat for feeding purposes. Mostly, sponges and tunicates in the wild serve as its diet. Moreover, marine algae, plant matter, small invertebrates, worms, and other tiny organisms are included in its dietary routine.

Along with that, it’s crucial to supply a genuine and varied diet to keep the regal angelfish fit and healthy. For this purpose, providing a mixture of seaweeds, mysis shrimp, brine shrimp, and chopped seafood blends (mussels, clams, squid) is well and good. Vegetables like spinach, lettuce, husked peas, and various frozen items can also be offered to Royal Angelfish.

However, for consistent feeding, quality commercial foods (including pellets, flakes, and granules) specially designed for marine fish are accessible.

Note: Make sure you feed your angelfish multiple times a day with small portions of food. The uneaten food should be removed from the tank, to ensure water quality. 

Regal Angelfish Common Diseases and Their Treatment

Despite their marvelous look, royal angelfish have the same health issues as other marine fish. They may acquire illnesses just like any other aquarium species, so it’s critical to identify and treat any symptoms as soon as possible.

Here are two common diseases that may affect Regal Angelfish, including Ich (White Spot Disease) and Velvet Disease (Oodinium).

  • Ich (White Spot Disease)

The prevalent disease Ich, also known as White Spot Disease, may affect Regal Angelfish. Ichthyophthirius multifiliis is a microscopic organism that is the cause of this parasitic infection.

Angelfish that are sick get little white cysts on their gills, fins, and skin. Aquarium enthusiasts commonly use a treatment containing formalin or copper to treat Ich, being sure to properly follow the dosing guidelines. A small increase in water temperature could speed up the parasite’s life cycle and increase its resistance to medication. Furthermore, keeping the infected fish apart in a quarantine tank while getting treatment aids in preventing the disease’s transmission to other fish in the tank.

  • Velvet Disease (Oodinium)

Regal Angelfish are at risk for Velvet Disease, which is a tiny parasitic disease caused by the parasite Oodinum that appears as dust that is either golden or rust-colored. Lethargy, rubbing, and respiratory discomfort are observed in fish.

Cautious quarantine procedures and stress management are part of prevention. Treatment involves giving specific instructions for how to take copper or formalin drugs in a separate tank. Raising the temperature can improve the efficacy of treatment. Maintaining water quality promotes healing while preventing the spread of the disease by isolating affected fish.
