Koran Angel Juvenile ( 7 days for delivery )

About this fish

What is its maximum size?
The juvenile Koran Angelfish (Pomacanthus semicirculatus) can eventually grow to approximately 40 cm (16 inches) in length.
Although juveniles are commonly sold at around 5–10 cm, they grow into substantial adult marine angelfish and require a very spacious aquarium.
One of its most fascinating characteristics is its dramatic colour transformation as it matures.
Juveniles: Dark blue-black bodies covered in beautiful curved white and electric-blue semicircular markings.
Adults: Develop a greenish-yellow and brown body with numerous blue spots, blue-edged fins and elongated dorsal and anal fin extensions.
The transition towards adult coloration generally takes place over a size range of approximately 8–16 cm. 


Where is its origin and where is it exported from?
The Koran Angelfish originates from the tropical Indo-West Pacific region.
Its natural distribution extends from the Red Sea and East African coastline across the Indian Ocean and western Pacific, including:
Red Sea.
East Africa.
Indonesia.
Philippines.
Sri Lanka.
Maldives.
Southern Japan.
Northern Australia.
New Guinea.
Fiji and surrounding Pacific islands.
Juveniles are commonly found in shallow, sheltered reef environments, lagoons and protected coastal areas, where they use coral formations and rocky crevices for protection.
Adults generally inhabit more exposed coastal reefs with substantial coral growth.
It is commonly exported for the marine aquarium trade from countries including Indonesia, the Philippines, Sri Lanka and other Indo-Pacific locations. 


Is it reef compatible?
Juveniles: Reef safe with caution Juvenile Koran Angelfish are sometimes considered more reef-compatible than adults. However, they should not be regarded as reliably reef safe.
As they mature, they develop stronger grazing and picking behaviours and may begin targeting corals and ornamental invertebrates.
Potential targets include:
LPS corals: May nip at fleshy coral polyps.
SPS corals: May pick at coral tissue and polyps.
Soft corals: Certain species may be targeted.
Zoanthids: May nip at individual polyps.
Clams: May pick at the mantle.Tubeworms: May be targeted.
Even though juveniles may initially coexist with corals, their eventual adult behaviour should be considered before purchasing one.
For long-term success, a fish-only-with-live-rock (FOWLR) aquarium is the safer option. Sponges and tunicates: Important components of their natural diet.



What should I feed it?
The juvenile Koran Angelfish is an omnivore with a natural diet consisting of sponges, tunicates, algae and other reef-associated organisms.
A varied and nutritious diet is particularly important during its juvenile growth stage.
Recommended foods include:
Marine algae and nori.
Spirulina-based foods.
High-quality marine angelfish preparations containing sponge.
Frozen mysis shrimp.
Enriched brine shrimp.
Chopped shrimp, squid and other marine seafood.
Quality marine pellets and flakes.
Fresh macroalgae.
Sponge-based foods are particularly important for supporting its nutritional requirements.
Regular feeding of algae-based foods also helps maintain a balanced diet and supports its natural grazing behaviour.
Several smaller meals throughout the day are beneficial, particularly during acclimatisation and early growth. 


How many can I keep?
The juvenile Koran Angelfish is best kept singly in most home aquariums.
Although juveniles may initially tolerate other angelfish, aggression can develop as they mature and establish territories.
Keeping multiple Koran Angelfish is generally not recommended for typical home aquarium setups.
If attempting to keep multiple large angelfish, an exceptionally spacious aquarium with carefully planned introductions and plenty of hiding places is essential.
For most aquarium setups, keeping one specimen is the recommended approach.
How compatible is it with other fish?Juvenile Koran Angelfish are generally less territorial than mature adults, although individual temperaments can vary.
They can be suitable for established marine community aquariums with appropriately selected tankmates.
Potential tankmates include:
Tangs.
Clownfish.
Larger wrasses.
Rabbitfish.
Triggerfish.
Groupers.
Other robust marine community fish.
Avoid housing them with aggressive fish that may bully them or prevent them from feeding properly.
As the Koran Angelfish matures, its territorial behaviour can increase considerably, particularly towards other large angelfish and similarly shaped species.
