About

Lapis Lazuli medaka is a beautiful improved variety whose deep lapis-blue body recalls the gemstone lapis lazuli. Combined with external body light, it gives off a mystical shimmer like a natural stone flecked with gold dust. Standard body type, roughly 3–4 cm. The lapis blue shows deepest and most beautiful in dark containers viewed from above, making it a favorite among blue varieties. Hardy across roughly 5–30°C in neutral to slightly alkaline water. Selecting individuals with strong external light and blue tone maintains and improves well-colored strains. Because color depends heavily on container color and lighting, dark containers under bright natural or LED light are ideal for display. Peaceful and community-compatible, and not difficult to keep.
