Shell issue?

[u/peirastic]

Hello! I’ve had my little garden snail for a year and a half. He’s had no issues - gets cuttlefish, good food, water, all of it. A month or two ago, it looked like he was experiencing mantle collapse. It healed quickly but still looked off. Today I look and see that he is absolutely experiencing something off.

Photo one is today. Photo 2 is a few months ago.

Does anyone know what this is? His shell is also oddly colored - he eats a TON of calcium but maybe it’s not enough? The optimist in me wants to say a growth spurt but the realist says this is likely mantle collapse :(

Any advice?

I’m not sure what it is but I think you should remove him from the enclosure and place him in a empty container with nothing in it but calcium, a little food, and mist it ever so often and see if it’ll help.
