Double Sword Japan Blue Endler Guppy (Mixed grading)

Double Sword Japan Blue Endler Guppy — Mixed Grading

The Double Sword Japan Blue Endler Guppy is a stunning hybrid strain that combines the vibrant iridescent blue body of the Japan Blue guppy lineage with the elegant double sword tail extension — producing a fish of exceptional colour and form. Available in mixed grading, each fish carries the signature Japan Blue sheen with varying degrees of sword tail development and pattern intensity, making every individual unique.

Japan Blue — A Colour Like No Other

The “Japan Blue” trait refers to a distinctive metallic blue iridescence that covers the body of the fish, shifting and shimmering under aquarium lighting. Combined with the double sword tail — where both the upper and lower edges of the caudal fin extend into elegant sword-like projections — this strain is one of the most visually striking guppy varieties available. Males are the showstoppers; females are larger and more subtly coloured.
