Last year I had a couple of snails mate and I decided to keep a clutch of their eggs. They had all been growing well and I followed the culling process, so in the end I had three good babies.

I noticed recently that they seemed to be sleeping all the time. They were sealed up and wouldn't even wake up to get food. I wasn't worried about humidity and temperature because since they're big enough they share a tank with other grown up snails and the grown-ups are fine. But a couple days ago, I noticed one was dead cause of the way its foot looked. And then yesterday I placed a food dish in the tank and I found another baby dead this morning on the food plate.

I don't really know what's wrong and I'm really bummed out because these babies are from two snails of mine that have already passed so I really wanted them to grow up well, but now I only have one of their babies. Does anybody know what could be wrong?
