guess i need to get some males! another question, I bought a cherry shrimp a while back from the lfs, she must have been pregnant because i have a bunch of juveniles now, some have red color the other are clear, even ones that are about the size of a dime are still clear. The cherry shrimp i bought, had yellow shrimp in the same tank. Its possible they cross-bred, but that still makes them Neocardnia, right. So they wont cross-breed with my Cardina?
