Hi!

What is this crawling on my glass and is it harmful. I swear it goes away and comes back to the same spot on the glass. It almost looks like coralline with a brownish outline.

Looks harmless. Hard to be sure but my best guess is a chiton. Maybe a stomatella or limpet. All are no issue. a clearer pic would help

I'm going with limpet. Looks exactly like the ones I have in my tank.

Regardless, everything suggestion is good for your tank.
