The right kind of soil...

[shaydeesnail]

My C. Nemoralis don't like to stay on the floor of their tank. At all. They barely venture down unless I put them there.
It occurred to me that they are very common in my Grandma's garden and the surrounding areas, but near where I live (and where their soil is from) there are none of these snails at all, there isn't even that many Helix Aspersa around here... And I live less than 5 miles away from my Grandma.

Could it be the type of soil around here? I read that if there is not enough calcium in the soil, or the soil is too acidic, then snails will try to avoid it.

Is there anyway I can recreate this "snail-friendly" soil for them? Can I simply add calcium to the soil myself? Would adding clay to the soil help maybe?

You could try adding powdered limestone to the substrate. Which substrate are you using now? When was the last time it was changed? Maybe they don't like the texture of it. It could be all kinds of reasons why.

How long have you had your snails? Maybe they are just hibernating for the winter? My Theba pisana is up on the lid all the time now that it's cold.

C. nemoralis don't spend much time on the ground in the wild either, but mostly lives in bushes and tall plants. I wouldn't worry about it much.

Agreed.
This species spends alot of time resting on plants and walls, and in captivity will gather on the wall of the tank or on plants and branches.

You could try placing natural organic compost as a base, along with some damp moss

My old snails didn't go on the ground but my new ones do. My New snails have different soil so its probably linked
