1. Origin and Background of Yellow Galaxy Guppy
The Yellow Galaxy Guppy is a selectively bred strain developed by enthusiasts aiming to produce guppies with vivid yellow coloring and shimmering, starry patterns resembling a galaxy. Like most fancy guppies, this strain traces its roots to wild guppies from South America, particularly from Venezuela, Barbados, and Guyana.
Selective breeding has emphasized:
- Bright yellow body coloration
- Galaxy-like speckles and mosaic patterns
- Long, flowing fins
- Big tails with multi-color accents (sometimes red, blue, or black)
- Hardiness and active swimming behavior
This strain has become increasingly popular in the aquascaping and ornamental fish communities due to its striking beauty and ease of maintenance.
2. Physical Appearance
Coloration
The most distinctive feature of Yellow Galaxy Guppies is their bright yellow base color that often covers the body, dorsal fin, and tail. The “galaxy” pattern typically consists of irregular dark spots, speckles, or a mosaic pattern, mainly on the tail and sometimes on the body.

Sexual Dimorphism
- Males are smaller, more colorful, and have a gonopodium (modified anal fin).
- Females are larger, less colorful, and have a rounded anal fin.
