Breeding, husbandry and quality assessment
For a new colony, confirm the supplier's exact biological species/stock background, mature appearance, water chemistry, GH/KH, conductivity and temperature before using any generalized genus parameters. To verify inheritance, record sexed parental pairs, source locality, F1/F2 offspring denominator and graded traits. Selection labels (OE, metallic, Rili, fancy) do not establish a universal allele or crossing recipe.
