It'd be awesome to train them to become SSS, my ramshorns float themselves to move around the tank all the time and occasionally a shrimp will perch on top of a floating snail, I'm sure it happens more than I can catch because I've seen them riding on top of snails while they climb up glass all the time!
Would you buy a shrimp if it surfed your snails all the time?! That'd be sweet.
