Live Rock Hitchhiker ID

[HTXReefer]

I am not sure what these are. They had to have come in on the live rock I have in my 20 gallon. Excuse the algae going through the heart of the uglies right now. Not sure what these are they’re kind of cool looking. Just looking for some help identifying.

Tbey almost look like little anemones. But without clearer pics, it’s hard to say for sure.

Looks like flat worms of some kind. I'd remove them until you get a confirmed ID.

I don’t think they are flat worms. They don’t move at all. Don’t think they are anemones. They scrape off really easy. Kind of cool looking and only one the glass and AIO section of the tank. Just wondering if they are harmful or not

Keyhole limpet
Most likely.

Are they good or bad???

I never ran into one that gave me issues. Usually just a herbivore. Keep an eye on it, just incase.
