Comprehensive Guide: Annularis Angelfish (Pomacanthus annularis)

Habitat

The Annularis Angelfish is native to the Indo-Pacific region, including the Red Sea, the Maldives, and the Great Barrier Reef. It inhabits coral reefs and lagoons, usually found in depths between 5 and 30 meters.

Reef Safe

The Annularis Angelfish is not considered reef safe. It has a tendency to nip at and potentially damage corals, especially soft corals and stony corals with large polyps.

Size

The Annularis Angelfish can grow up to 15 inches in length, making it a relatively large fish for a saltwater aquarium. It requires a spacious tank to accommodate its size.

Temperament

The Annularis Angelfish is known for its semi-aggressive nature. While it may be compatible with some tankmates, it can become territorial and aggressive towards other fish, especially similar-looking species.

Sexual Dimorphism

There are no distinct visual differences between males and females of the Annularis Angelfish species.

Lifespan

In proper conditions, the Annularis Angelfish can live for up to 15 years or more in captivity, given that it is provided with a suitable diet and a well-maintained aquarium environment.

Diet in Aquariums

The diet of the Annularis Angelfish should include a variety of foods. It is an omnivore, so a mix of meaty foods (such as frozen or live brine shrimp, mysis shrimp, and chopped seafood) and plant matter (such as spirulina-based flakes or pellets, nori seaweed, and algae sheets) should be provided.

Aquascaping Recommendations

When setting up the aquarium for the Annularis Angelfish, it is important to include plenty of hiding places and live rock formations to mimic its natural habitat. Provide open spaces for swimming and ensure a well-established coral reef structure if keeping it in a reef tank.

Captive Bred Availability

The Annularis Angelfish is rarely available as captive-bred specimens in the aquarium trade. Most of the specimens offered are wild-caught, so it is important to source them from reputable and sustainable suppliers.

Compatibility with Other Fish, Invertebrates, or Corals

The Annularis Angelfish can be kept with larger, semi-aggressive fish species in a spacious aquarium. However, caution should be exercised when considering tankmates as they may compete for territory and food. It is not recommended to house the Annularis Angelfish with smaller, passive fish or delicate invertebrates.

• Five specific tankmates for the Annularis Angelfish are:
• Lionfish – They are similarly sized and have a similar temperament, making them suitable companions.
• Triggerfish – Some larger triggerfish species can coexist with the Annularis Angelfish, provided there is enough space in the tank.
• Tangs/Surgeonfish – Some tang species, like the Powder Blue Tang or the Yellow Tang, can be compatible tankmates as they occupy different areas of the tank.
• Angelfish – Other large, non-congeneric angelfish species can sometimes coexist with the Annularis Angelfish but careful observation is needed to ensure compatibility.
• Wrasses – Certain wrasse species, like the Six Line Wrasse or the Melanurus Wrasse, can be suitable tankmates as they can help control pests and add color to the tank.

Other Common Names

The Annularis Angelfish is also known as the Blue Ring Angelfish or the Blue Ringed Angelfish.
