I got a nerite from my LFS today and due to lockdown restrictions in my area I couldn't go in and pick one, instead they just pick one and bring it out. I noticed when I got home that it is missing the tip of its shell, it looks like it was broken off, and you can see a bit inside. It's also got a couple chips in its shell near the front. It seems to be doing fine, it's moving around and eating. I have seen other posts saying the tip of the shell can turn white from lack of calcium, but here it seems the tip of the shell has been broken off.
Just wondering if theres anything I can do to help my little snail, or if this is something to be very concerned about. I have pretty hard water so I'm hoping that will help prevent further breakdown of the shell.
