I've been selectively breading ramshorn snails for a few years now and came up with a stable pink and white line. These little critters are grate at eating algae and leftover fish food. Helping to keep your tank nice and clean. They are prolific so if you have a lot of algae. You'll get a lot of snails. Once it's all clean, many will die off and only a few that can be sustained by the growing algae and excess fish food will stick around. So don't worry if you get a bunch of babies at first. You can alwasys get a glass cup and put some fish food into it and they'll all come running, or creeping. Then toss them in the garbage. NOT down the drain. I have a bunch because I enjoy breading them and seeing what colors I can make. I'm selling them $1 each 10 minimum, cash please. I also have plants for sale on other listing's if your interested. Thanks for taking a look and happy fish keeping.
