I have to second this. The most GORGEOUS coral glow I've ever produced came from the same coral glow male that produced my drabbest/lowest-quality coral glow. So, even though both babies had the same coral glow father, they had different mothers, and that made all of the difference. The nice one came from a high contrast albino female, and she passed on some incredible genes for yellow/orange coloration and sharp contrast. The ugly one came from a dinker female that I purchased years ago because she looked like an axanthic (in other words, she had very LOW yellows and low orange underlying her natural pattern... in retrospect, not the best traits for a coral glow).
Mendelian traits such as "Coral Glow" don't require a ten-generation pedigree to be beautiful animals... they just need to look beautiful... you can see exactly what you're getting, and you get what you pay for.
