I have at least 60 ramshorns that need a new home. Most are leopard spotted, some with reflective gold, a few are solid chocolate. Also have a bunch of tiny mini-ramshorns. I'm located in the NW burbs and can drive to meet you most weekday mornings, or I can hold them for you till the swap.
They're great cleaners and are quite fun to watch floating in the tank and speeding about.
