Or other dark colored mystery snails. A clutch from dark colored snails will also work, but you'll have to tell me how to hatch it because I have no idea lol. If the snails are coming from a tank with fish and you are having ANY health issues, please let me know what they are. I won't be upset, it's just that I have no idea how hardy my fish are, as they are a new species, and I am trying to limit contaminants to their tank for that reason. I will just want to QT the snails/clutch before adding them to the tank. Okay, so, if you have what I'm looking for, shoot me a pm with price and shipping to 91948. Thanks!
