Care, selection, authentication
Maintain lineage-specific stock labels, isolate genuine known mating pairs in a matured tank, document sex and source of each parent, hatch-date cohorts and scored F1/F2 offspring. Color and orange eye often segregate differently in breeder accounts. Record water parameters rather than assuming one eye-color gene governs body color.
