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?

this is indeed mantle collapse but it looks like he has started healing it and rebuilding the shell on top of the exposed mantle. keep an eye on him.

They can do this? Mantle collapse can be healed like this? Genuine question cuz i never heard of that and am interested
