Re: [GSAS-Member] blue pond snails?

[Steev Ward <steevward@yahoo.com>]

I've seen snails do that. Some people really like the look. But they always 
seem really
thin-shelled and I think it has to do with erosion of the shell, which would 
probably
mean they are missing something in the diet. And I think it happens when there 
are too
many snails for the food supply - so they can't maintain their shell. With or 
without
good water chemistry, they still have to eat, or their shells will dissolve.

On the other hand, they do chew on each OTHER'S shells when they are crowded.
