Tips on Koran Angelfish Care

Koran Angelfish or Pomacanthus semicirculatus belong to the family Pomacanthidae . This species is endemic to the Indo-Pacific and Rea Sea as far away as Samoa. Their geographical spread extends from Japan along the east coast of Africa to western Australia and New South Wales. They are reef fish that occupy depths of 3 to 100 feet.

One of the common features in large angelfes is the dramatic change in transition between the juvenile and adult phases of their lives. It is simply incredible to watch a progressive metamorphosis of the juvenile in its palette of adult colors. The Korans undergo three distinct stages on the stay at adulthood. The Greek word semicirculatus refers to the initial phase of their lives. Koran babies have black bodies with blue and white stripes that develop concentrically from the base of their tail. This pattern closely resembles half the ripples on a pond again when a pebble is suddenly thrown into it. A Koran baby could easily be confused with an angelfish juvenile emperor. A closer look reveals that the Koran have wider stripes and fewer of them. When these fish reach about 3 inches in length, semicircular marks slowly straighten up in the sweeping lines. At about five inches in length, the fish begins to show patterns between the blue lines on the tail 's aileron that resembles the Arabic script, hence the name Koran angelfish. They show a combination of juvenile and adult coloration. This marks the conclusion of the second stage. At about two years and between 6-7 inches in length, this species turns into an adult color palette. Adults are usually yellowish-green in color with varying amounts of blue or brown spots on their bodies and caudal fins. Their heads can be blue or their main dye. The gills and fins are highlighted in blue. This species is marketed by the aquarium industry under the following names; Angel of the Koran, Angel of the Blue Koran, Angel of the semicircle, Angel of semicircle and angel of the Semicircle.

These fish will reach a maximum length of 16 inches in adults. Because of their size, they will need a large aquarium. A minimum of 135 gallons is recommended. A well-populated multi-species reservoir should be considerably larger.

This fish has a semi-aggressive temperament. It can intimidate the smallest fish. It will ignore for most other larger species. However, it will display a major territorial behavior towards the conspecifcipales and the other angels. It is advisable to keep only one large Anglo-Saxon fish of one species in an aquarium.

Many species of wide angles possess a level of specialized care. The Korans are classified as moderate. A healthy Quran can live 15-20 years.

The Korans are omnivorous. In their nature, their diet consists of a mixture of corals, algae, sponges, worms, molluscs and crustaceans. Their eating habits make them unsuitable for a marine reef aquarium. However, they will require a wide range of living rocks for a fish of their proportions. Having a food source that they are used to will help in the process of acclimatization. You can begin to train them to recognize the price of the aquarium as an acceptable food source by mixing increasing amounts with live food offers such as brine shrimp. This is the best technique for weaning from living food. Be sure to choose a high quality food product formulated for marine angels. Once they have been successfully eliminated, their diets may be supplemented by the following: Crustaceans and fresh molluscs, chopped for protein, table vegetables such as chopped spinach, zucchini and yellow squash for Vegetable matter, frozen or dried seaweed such as algae leaves to ensure a balanced diet.
