My mystery snail has a weird shell thing going on. This brown spot:
It is not as deep as it looks it's just really dark brown towards the middle area.
Is this a calcium deficiency? I have looked for cuttlebones and haven't been able to find them. I feed them algae wafers. They are not at my house so I do not have vegetables to feed them. I am moving them this week though to a house with a readily available source of kale. Would kale help any? Or would they even eat kale?
Also I just tested my water and it is hard apparently but I thought that was good for their shells.
