I raise colored ramshorn snails (pink, red and blue). Every so often I have to cull to keep the colors true. I have appx 50 culls. They are dark, almost your common ramshorn. They were culled from my reds and blues. They are free to anyone who wants them. I can ship them priority in a medium flat rate box or you can pay actual shipping cost. There is no DOA guarantee because they are FREE. First come, first served.
