Hi,

The piece of Mopani wood I have in my tank is covered with little white dots. It looks ugly and I wonder if it is some disease. They are flat and white. I crushed them and it feels like a thin eggshell. There is nothing under them. When I scratch them off the wood, it leaves a little dip.

I included a picture. Sorry, the quality is not great. On it you see the wood, the zebra snail and the dots.

Could it be the zebra making those?

Thanks for your help.
