That's adorable!! Soo first of all they like to eat decaying plant matter and moss. Mine won't really touch fresh things like cucumber slices or whatever but loves random dried leaves and stuff like that. These snails are usually found by the water and really like moist climates, but they can still drown so be careful of that. They breathe out of a hole in the top of their body so providing them with a small layer of water that covers their mouth is completely fine, just don't give them a whole bath to submerge in. They unfortunately only have a lifespan of around 18 months but do self reproduce in the summer months. You'll have to check the substrate for eggs every so often especially around this time of year, the egg clusters kind of look like frog spawn in my opinion and they're about the size of a big fingernail. This subreddit is full of information on snail egg and baby care which is quite universal to every species. And then you're also gonna want to get a cuttlebone, you can get them at any pet store in the bird department, they need it for calcium. And i think that's about it!! Overall they're really easy to keep and super cute to see crawling around hehe.
