Origins of the Moscow Red Guppy

The Moscow line of guppies originated in Russia during the 1980s, where breeders worked to create guppies with solid body colors instead of the traditional spotted and patterned looks. Over years of selective breeding, they succeeded in producing guppies with full-body pigmentation.

The Moscow Red Guppy is one of the rarest and most sought-after variations of this line. Through careful genetic refinement, breeders developed this strain with a rich, solid red hue across the entire body and fins. Today, it is prized not only by hobbyists but also by guppy breeders aiming to preserve and improve its purity.
