The Pomacanthus Semicirculatus - Blue Koran Angel - Juvenile is a high-performance architectural specimen, prized for its dramatic ontogenetic transformation and technical presence in the marine system. Characterized by a striking "half-circle" pattern of iridescent blue and white concentric rings against a deep black-to-navy body, this Juvenile variant is a masterclass in geometric aquatic aesthetics. In the "Answering Machine" era of specialized marine husbandry, the Koran Angel is recognized as one of the hardier large-body angels, serving as a gateway centerpiece for those transitioning into sophisticated marine management.
Unlike their adult counterparts which display a greenish-yellow earthen profile, the juvenile stage is a high-contrast visual asset. They are exceptionally active foragers that occupy the middle and lower levels of the water column, providing a constant display of color and alert, inquisitive movement through rockwork.
Note: Images shown are stock images and not the actual fish you will receive. Visualization Note: Some product imagery utilizes generative AI to provide a high-fidelity representation of a mature specimen’s architectural profile. These are not photos of the specific individual you will receive, as biological variance is a standard in high-end husbandry.
Care Level: Moderate
Temperament: Semi-Aggressive
Variant Size: Small / Medium / Large
Minimum Tank Size: 125 Gallons (Long-term)
Diet: Omnivore (Requires sponge-based nutrients)
Reef Compatible: With Caution (Known to nip corals/clams)
Max Size: 15 Inches
Temperature: 72° to 78°F
dKH: 8 to 12
pH: 8.1 to 8.4
Specific Gravity: 1.020 to 1.025
The Koran Angel requires a high-volume system with significant structural integrity to accommodate its growth and foraging behavior:
Structural Layout: Significant live rock with numerous caves and deep crevices is mandatory to provide security and natural grazing surfaces.
Swimming Space: Large, open horizontal runs are required for this active swimmer.
Maturity: Introduce only to a well-established system with stable biological filtration.
As a semi-aggressive species, the Koran Angel should be one of the last additions to the tank. It will establish a territory and may be aggressive towards other angels or similar-shaped fish. They are "reef-safe with caution" as they are prone to nipping at stony corals, soft corals, and clam mantles. Pair with robust tank mates like larger Wrasses, Tangs, and Damselfish.
Success with Pomacanthus semicirculatus hinges on a diverse, high-frequency nutritional protocol. They are high-metabolism foragers and should be fed at least 2 to 3 times daily. Their diet must include specialized marine angelfish preparations containing sponges and spirulina, supplemented with high-quality mysis shrimp and other meaty marine items. Maintaining stable water parameters and high dissolved oxygen levels is the primary success factor for long-term vitality.
We utilize specialized logistics for national Overnight Delivery to ensure livestock arrives in peak condition. Every order is packed using professional-grade insulation and climate-contingent heat or ice packs to maintain stable temperatures throughout the journey. This protocol is strictly designed to minimize transport stress and ensure a technical transfer from our facility to your tank with zero compromise on health.
