Angel-Koi

Description

Koi Angelfish are one of the most striking colour varieties of the freshwater Angelfish, featuring a beautiful combination of white, orange, yellow, and black markings reminiscent of traditional Japanese Koi. No two fish share the exact same pattern, making each individual truly unique. Their graceful fins and elegant swimming style make them a stunning centrepiece for planted and community aquariums.

Peaceful yet semi-territorial as they mature, Koi Angelfish thrive in tall aquariums with plenty of swimming space and vegetation. With proper care, they become confident, interactive fish that can live for many years.

Breeding

Koi Angelfish form monogamous pairs and may spawn on flat surfaces such as broad plant leaves, slate, or driftwood. Both parents care for the eggs and fry, although some captive-bred pairs may eat their first few spawns. Warm, clean water and a protein-rich diet encourage breeding.
