Albino individuals lacking melanin pigment. Characterized by red eyes and white body with a mystical atmosphere.
Albino medaka is a mutant form lacking melanin pigment, characterized by white-to-cream body color and red eyes (blood vessels visible through pigment-free irises). Their mystical appearance earns them enduring popularity. Being albino, they are UV-sensitive — strong direct sunlight must be avoided. Weaker eyesight than normal individuals means food should be distributed evenly across the water surface, and competition at feeding time should be minimized. Avoid keeping with aggressive fish; albino x albino or peaceful variety communities are recommended. Albino x Albino crosses produce albino offspring at higher rates, though hatch and survival rates may be lower than normal medaka.
The Albino Medaka lives 2-3 years.
The Albino Medaka grows to 2-4cm.
The ideal water temperature for the Albino Medaka is 18〜24℃.

Selectively bred killifish are trait combinations of body form × body color × pattern × luminescence (internal/external) × scale types (transparent scales) × sparkle × fin morphology and so forth. Published entries include only confirmed traits constituting the given variety, with genetic inheritance patterns provided only for confirmed traits (uncertain cases omitted). Genetic patterns are provided as reference for breeding.

Artificial feed, Daphnia
It is sensitive to UV, so avoid strong direct sun and keep it in bright shade. Shade from aquatic plants helps it settle.
Eyesight is poor, so make sure food reaches it
Adapts to 5-30°C and neutral to slightly alkaline water, but is sensitive to sudden changes, so change water in small amounts.
Avoid aggressive tankmates; keep it with other albinos or gentle varieties. Its eyesight is weak, so limit competition for food.
Albino x albino pairings produce albinos
Albino x albino pairings can have lower hatch and survival rates than normal fish, so manage eggs and fry carefully.
