So I have a good batch of RCS going in my heavily planted 10gallon tank. I want to try to selectively breed some of these shrimp cause even though the oldest shrimplets are only a week and a half it is very apparent that some of the females are much more red than others. I have a 30gallon heavily planted tank that I want to move the reddest females in order to breed the best color ones in the 30gallo tank. Here is my question: What is the best way to pick out which males to move into the 30gallon tank? Do I just pick the ones with the most red spots on them or is there something more particular I could look for that would indicate good health or color?
