Originating primarily in guppy farms in Southeast Asia and Europe, the Topaz Blue strain was developed by enhancing blue genes and combining them with metallic and reflective traits.

The goal was to mimic the sparkling, cool hue of the gemstone “topaz” while maintaining the guppy’s well-known resilience and peaceful nature.
