A mystical medaka with glittering lame on a black body, like stars in the night sky.
Black lame medaka is a mystical improved variety with glittering iridophore lame on an Orochi-lineage jet-black body, like stars twinkling in a night sky. The contrast between jet-black body and sparkling lame is its greatest attraction — the achromatic black background makes the lame shine all the more intensely. Dark containers best showcase both jet-black body and lame sparkle together. Sunlight and LED lighting produce the most varied lame shimmer. Inherits Orochi's lack of background adaptation, maintaining black in white containers too. Selective breeding of densely lame-covered individuals improves lame quality. A consistent bestseller alongside Black Diamond among black lame medaka.

Feed mainly medaka food, supplemented with live food such as daphnia. Leftovers foul the water, so watch the amount.
Easy to breed and spawns readily when a spawning mop is provided. Pairing individuals with dense lame improves lame quality.
Gentle and fine with other peaceful varieties. Avoid housing it with aggressive fish.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Black Lame Medaka is 18〜24℃. Avoid sudden temperature changes and maintain a stable environment.
