How we choose a breeding pair.

Locale match first. Health second. Coloration third. Disposition fourth. Reverse the order and you produce visually striking animals with shorter careers.

How we choose a breeding pair.

We will not pair across locales. Within locale, we look for proven longevity in the parents — animals over four years old, weight stable, clean veterinary record. Coloration is the last filter applied, not the first one. A male with extraordinary color and an early metabolic crash is not a breeder we want.

Disposition matters because temperament is heritable in subtle ways. A pair with calm handling tolerance produces juveniles that calibrate to keepers faster, which translates to lower stress in the new home and longer working lives.
