Breeding for grade, not for volume
I started with B and A grade stock. Red crystals are graded on colour coverage and depth, and moving a line up takes generations of keeping the best animals and culling the rest.
The aim was to raise the whole line, not produce one showpiece. Chasing a single perfect shrimp narrows the gene pool and the line collapses within a few generations. By the end I was near a stable SS, with the occasional SSS sold at a premium.
