Do they breed for you?Lol, well when they're crawling next to the front glass, you can watch them grab a shrimp turd with their mouth. Not sure if they eat it then or save it for later, but it goes in, and I don't feed them anything, I use a feeding dish.
Your site is where I saw them.most snails if you want to keep them should have them in a 7ph or higher and semi hard water really helps with their shells. they are bigger then MTS. really neat snail.
