What's that?

Hi everybody!

This morning I found that in the glass of the aquarium but I don't know what it was. Does anybody know?

Looks like a limpet.

Thank you @Ramblin Rose!
I think you're right.

Last day it was stopped on the upper side of the tank and I was able to touch it and It has hard cover (no soft as it seemed to me).

So yes, it's a goog worker for my tank.

It's a chiton, harmless grazer.

Chiton, not limpet. Limpets are more pyramid shaped

I agree with Chiton
