One time I had a pet pond snail, had sand and fake lava rocks with it.Lived for about three months, then died was it just old?
No. Unless it was 14 years old when you adopted it. Snails can live up to 15 years!
Maybe. You seem responsible with it, so I don't figure anything else. Like lack of food,
No, it wasn't old.
Snails can live along time
