Unlike many other strains with multicolored patterns, the Moscow Green Guppy boasts a solid, rich, and uniform color that runs across its entire body and fins, making it an impressive centerpiece in any freshwater aquarium.

The Moscow strain has become extremely popular among breeders and collectors due to its striking appearance, genetic uniqueness, and potential for selective breeding. If you’re interested in keeping Moscow Green Guppies, this guide will walk you through everything you need to know—from tank setup and diet to breeding, health care, and aquascaping ideas.

Origins of the Moscow Green Guppy

The Moscow strain of guppies originated in Russia during the late 20th century, where breeders developed guppies with intense, full-bodied colors unlike the traditional patterned guppies. These guppies were then selectively bred and exported worldwide, becoming highly valued in the guppy hobby.

The Moscow Green Guppy is a result of careful genetic refinement within the Moscow line, showcasing a deep emerald-green sheen that glows under proper lighting. Unlike patterned strains, Moscow guppies are admired for their solid color coverage, often extending from head to tail without breaks.

• Size: Males reach about 1.5–2 inches, while females are larger at 2–2.5 inches.
