Koran Angelfish – LiveAquaria
The Koran Angelfish, also referred to as the Semicircular Angelfish or Halfcircled Angelfish, is an extremely popular and hardy angelfish. As an adult, the body color is a yellow-green that bleeds from light to dark moving front to back along the body. Lighter areas are speckled-blue while darker areas have a more yellow-speckled appearance. The head is a plain yellow-green with sapphire-blue gill margins and eye rings. The fins are also outlined in sapphire blue. The juvenile is black with white and blue stripes.
The Koran Angelfish requires a 250 gallon or larger tank with large amounts of live rock for hiding and grazing upon slime algae and cyanobacteria. It is prone to nip at stony and soft corals (sessile invertebrates) and clam mantles so it is not a good candidate for a reef tank.

The Koran Angelfish has been a great addition to our 300-gallon tank. It’s active and colorful, with a beautiful yellow-green body and blue outlines. We’ve had it for six months and it’s thriving. Just make sure to avoid placing it near soft corals or clams.

We bought this fish for our larger tank and it’s been very peaceful. The coloration is striking, especially in the light. It’s not aggressive, but does occasionally nudge nearby rocks. Good for experienced aquarists with large setups.

The fish has adapted well to our tank. The blue gill margins and eye rings stand out. We’ve maintained stable water parameters and it’s been active and healthy since arrival.
