I have never seen that before. However, looking closely at that shell, it appears that someone has attached (glued?) a different piece onto the existing shell.


no it is not glued. the newer shell is thinner maybe because of sudden change in calcium content in water when I bought it.


Good morning,

It appears to be new shell growth. I don't think it's anything to worry about.

I have moved your thread to the Freshwater Invertebrates/Snails section of the forum.



Whatever it is I like it


That happens to a lot of my different nerites when they are moved from one tank to another, especially if the Gh/Kh are different in the new tank. Just looks like new growth to me. I wouldn't be worried unless it starts to look unhealthy or broken.
