+1 smoothing shrimp
Just keep what makes you happy. If you are serious about breeding, then keep the individual colors separately to prevent hybridization. It seems only a small percentage of Shri,p buyers ultimately sell and ship shrimp offspring, and fewer cull. Some people just have a different reason for keeping these little guys purely for enjoyment and not profit.
I have a glass bowl with a Taiwan fire red, two oranges and a yellow (albeit females) but I gaze at this tank all day long next to my computer.
Do whatever makes ya happy but know that hybridization ruins the purity of each breeds color and likely their street value if you were to sell the offspring. If these were eventually going to be gifted, it would be nice if you tell the new owners they were hybrids as a courtesy.
