Hey, so today I was feeding blanched broccoli and carrots and I noticed that one of my Mystery Snails wasn't coming out to eat. I didn't think much of it because snails are pretty derpy and they tend to do their own thing. After a few hours I decided to sit down and try to find where the missing snail was in the tank. I found it laying upside down behind a rock. It's trap was open and it was beyond dead. If I had to guess it's been dead for at least 1-2 days. I really love my snails and they're my favorite inhabitants in my aquarium at the moment and I really don't want my other ones to die. I'll list details about my set up below, if anyone with more experience could help me figure it out I'd be greatly appreciative.
*Edit* - After I discarded the snails body I examined the shell and I found a tiny hole in it. The area by the hole was brittle, I was able to break parts of it off by applying light pressure with my finger nail.
