Koran Angel Fish J (Pomacanthus semicirculatus)

Species Name:

Pomacanthus semicirculatus (Koran Angelfish)

General Information:

Pomacanthus semicirculatus, or the Koran Angelfish, is a species of marine angelfish native to the Indo-Pacific region. Known for its striking colors and unique patterning, the Koran Angelfish is a popular choice for medium to large-sized saltwater aquariums.

Tank Requirements:

• Tank Size: A minimum tank size of 150 gallons is recommended for a single Koran Angelfish. Larger tanks are preferred for multiple individuals or if you plan to keep other large fish species.
• Water Parameters:
  • Temperature: 72-78°F (22-26°C)
  • pH: 8.1-8.4
  • Salinity: 1.020-1.025
• Substrate: A sandy substrate is preferred, as Koran Angelfish may sift through sand in search of food and may injure themselves on rough substrates.

Diet:

Pomacanthus semicirculatus are omnivorous but tend to graze primarily on algae and sponge material in the wild. Their diet should include:

• High-quality marine-based flakes or pellets
• Fresh or frozen marine algae (such as Spirulina)
• Occasional offerings of meaty foods like brine shrimp, mysis shrimp, and chopped seafood

Tank Compatibility:

• Aggression: Koran Angelfish can be aggressive towards other fish, especially towards other angelfish or similarly shaped species. They may also display territorial behavior.
• Tankmates: Best kept with larger, semi-aggressive to aggressive fish species. Avoid housing them with small, passive fish that may become targets of aggression.
• Reef Compatibility: Koran Angelfish are not considered reef-safe, as they may nip at or consume corals and certain invertebrates, particularly sessile invertebrates like corals and clams.

Behavior & Temperament:

• Semi-Aggressive: Koran Angelfish can exhibit semi-aggressive behavior, especially towards conspecifics or other fish with similar body shapes.
• Territorial: They may establish territories within the tank, especially in larger systems with multiple hiding spots and territories to claim.
• Active Swimmers: While not as active as some smaller fish species, Koran Angelfish are relatively active swimmers and appreciate ample space to explore.

Tank Environment:

• Rockwork: Provide plenty of live rock formations with caves and crevices for hiding and territory establishment.
• Plants: While not necessary, live rock with algae growth can provide a natural food source and enrichment for the angelfish.
• Lighting: Moderate to high lighting is preferred, as it mimics their natural reef habitat.

Maintenance:

• Water Quality: Regular water testing and maintenance are crucial to ensure stable water parameters. Perform regular water changes to maintain water quality and remove excess nutrients.
• Algae Control: Keep algae growth in check, as Koran Angelfish may help control algae but can also be selective grazers.
• Territorial Aggression: Monitor for signs of territorial aggression, especially if housing multiple angelfish or other potentially aggressive species.

Health Considerations:

• Quarantine: Quarantine new arrivals before introducing them to the main tank to prevent the spread of diseases.
• Parasites: Keep an eye out for signs of parasites, such as white spots or abnormal behavior. Treat promptly if necessary.
• Dietary Needs: Ensure a varied diet to prevent nutritional deficiencies and maintain overall health.

Conclusion:

Pomacanthus semicirculatus, the Koran Angelfish, is a stunning addition to a medium to large-sized marine aquarium. With proper care, a suitable tank environment, and a varied diet, they can thrive and become a captivating centerpiece in your reef or fish-only setup. Remember to provide ample space, appropriate tankmates, and regular maintenance to ensure the health and well-being of your Koran Angelfish.
