I had sakuras and snowballs in the same tank. The tank had a divider but a few slipped through the grate and nature took over. I wasn't sure which shrimp mated with which, but after a while I did have some wild coloration babies. When in mean wild it was different shades of brown. I had a few that had some green shell and brown overlay but I found out the food I was feeding them had dye. I thought it was a natural color guess I was wrong. The farthest I gone with them was second generation the color was still brown no real change in color. I had pictures but they were deleted sorry.
