(Pictures) I just captured this snail from my backyard as a pet. He looked fine when I found him, but now his shell looks a little off to me? When he climbs sideways on the tank his shell sags a little and he's been resting quite a lot since I brought him in (he also doesnt rest all the way in his shell all the time), and I dont think he's eaten at all. I've offered him a couple blue berry halves and a piece of salad lettuce. Is it normal for their shell to not be really stuck on them? Sorry if these are stupid questions lol, but I always thought their shells were stuck on pretty good. Also, any quick tips for a beginner to snails? Thanks!
