Well this one is a classic example of what not to buy when you look for a snail. I got this one 4 days ago and it didn't make it through today.
I wanted to show this to help others recognize what to look for when buying a snail. This is not a snail you want to buy, not in this condition anyway.
This erosion is the worst I have seen. The side of the shell is gone and the area where the door would close is so gone it could never seal completely.
This one I didn't see in the LFS. The end of the spiral is so eroded that the shell is almost transparent and there is a huge hole in it.
I hate to say it but don't try to rescue them. All the research I have done says they are too far gone when they reach this point. I tried to save them, even did special feedings but once the shell has degraded this far they are beyond saving. Hopefully this will help at least one person keep from making the same mistake I have made twice now. I am not mad at the LFS because this takes a long time to happen and the stock is new enough that it is not the LFS fault. The breeders take this poor of care of these creatures and gives LFS a bad rap. It is unfortunate that my LFS doesn't know better, but they will tomorrow.
If you have a snail in this condition even the slightest thing wrong with the water, trace amounts of copper that would normally be safe, any salt at all or anything wrong with the water any snail in this condition is a gonner.
Make sure to hand inspect any snail you are going to buy. Look at the shell through the light to make sure it isn't translucent. Check that the snail can completely close the door to the shell and it looks like it seals. Any serious divots in the shell or other erosion is a sign of a snail not taken care of and not a good purchase.
