Very very nice!!! Call them riddlers lol. They're green and people will have no clue where they came from when you get them breeding true
But about the separation.. If you keep a detailed log, you'll probably find some low grades carrying genes for high grades. Try to keep an eye on who breeds with who.
If you can get a sump type deal on the side of the tank with the same water, hatch females in there. You'll know exactly which shrimp gave what offspring.
