Shell development

[escargot5]

Hello,
I have many growing cepaea nemoralis snails from two wild caught parents. Perhaps not all, but many of them have sort
of dry looking, or rough textured looking shells. I give them cuttlefish and they eat it but maybe not a varied enough diet. ?
What could be the cause, or is this normal for them to have rough looking shells while they grow? The parents shells still look the same as when I caught them and there are some individuals which also look fine on their shell. Any ideas?
Thank you
Richard

Are there any thoughts on what I describe. Anyone?

I can't really say what could cause this,only that it isn't a normally thing to happen.What you said about their diet could be the problem.It is possible the shells will return to normal when they're adults....

I have no idea what may cause this but I know hat it has never happened to me. I have been keeping a couple of cepea nemoralis for some years now and they have had many babies and none of them have had this roughness you talk about.

This is kind of an old thread but I think I may have a thesis of why their shells are poorly developed. I have moved my cepea tank into another room and noticed that one baby had developed the same symptoms. My tank was moved to a less "sunny" place away from the window. May the shell development be because of lack of sun light? How much sunlight do your tank get?

is it possible that they have had their shells rasped and that has caused roughness? also as kanin said they may need more sunlight..
