Tumuki Medaka 3cm

The Tumuki Medaka (Oryzias latipes var.) is a rare and distinctive Japanese rice fish variety featuring the unique "Tumuki" (弦月) body trait — a naturally curved or arched spine that gives the fish a crescent-like silhouette when viewed from the side. Far from a defect, this is a selectively bred characteristic deeply valued in Japanese medaka culture for its unusual and artistic form. Combined with attractive colouration, the Tumuki variety is a true collector's piece that sparks conversation and admiration in any medaka display.
