Endler's Livebearer Genetics Guide — N-Class Maintenance & Selective Breeding

Endler's Livebearers are closely related to guppies, with vivid male patterns and strict purity classification that collectors take seriously.

Class System

N-Class (Pure): Documented collection locality, no guppy hybridization. Most valuable. P-Class (Presumed Pure): Believed pure but incomplete locality documentation. K-Class (Hybrid): Intentional guppy crosses. Beautiful but distinguished from pure lines.

Genetics

Many pattern genes are Y-linked (father to son). Color patterns fix relatively easily. Guppy hybridization disrupts patterns within one generation.

Maintaining N-Class Purity

Never house with guppies, maintain lineage records, source from trusted breeders, and attach lineage documentation to breeding stock.
