What Is This?

[Benji]

Was staring deeply into my tank tonight and saw this little guy. Have no idea what it is. Good or bad? Anybody know? Thanks.

Sorry, the white line across the picture is the cleaner shrimp. He likes to photo bomb my pictures.

Looks like a Limpet snail from the pics that I've seen online. Apparently some are safe and some aren't. You may have to research which one you have. Hopefully someone with more experience can give you a better idea.

Limpet...algae eater

If they are on the glass they are eating algae. My sump is full of them, with no issues. In the main display the wrasses eat them.
