Background / Strain Notes
Secret Weapon, known in Japan as Himitsu Heiki / ヒミツヘイキ, is a collectible Japanese medaka strain originally created by Gifu Dōsan Medaka / 岐阜・道三めだか.
This strain is known for its intense lame / ラメ expression, giving the fish a flashy glittered appearance across the body. Secret Weapon is associated with Rame-Ō Kai / ラメ王・改, meaning an improved Rame-Ō type selected for stronger and more stable glitter expression.
Japanese breeders and keepers describe this strain as having dense, bright lame that can appear almost body-light-like, while still showing as individual glitter scales. Color tone can vary between fish, with some showing warmer yellow, orange, brown, or darker tones depending on expression and environment.
Recommended Tub Color
For best visual expression, we recommend keeping Secret Weapon in a gray or moss-green tub. These colors help balance the body color while still showing off the glittering lame. Very dark tubs can make the body appear too dark, while pure white tubs may wash out the body color.
