My article Small Scale Guppy Breeding describes how I breed fancy guppies in just nine tanks. Articles covers the basics, but it contains new, vital information on guppy reproduction. Learn why I keep “chase” females with my juvenile males, why one female accepted and quickly mated with a new male but her full-sister rejected him… Learn the pros and cons of separating the sexes, how I breed for fitness… Overall, the article celebrates the guppy’s genetic trait of color polymorphism. Unlike breeding methods that emphasize strain uniformity, I work with the guppy’s natural tendency to produce different color patterns (Photo). This not only makes guppy breeding more fun but avoids inbreeding problems and genetic weaknesses.
