Are these limpets?

Looking an ID. I think maybe limpets along the bottom of this coral but am not good with IDing snails. The largest is 5-6mm the smallest 2-3mm . They appear to be reproducing in my SPS tank so I want to be sure they are not a threat to acros. I haven't seen any on coral but want to play it safe and get a positive ID.

I think so, or some related species.

Without seeing the tops of them I’m going to say they are limpets. I offer find them in my filter sock. But nowhere near that size. They’re great scavengers just keep an eye on them around your corals

Those are limpets. Not scavengers. They eat algae and other plants. No worries for your corals.

I had about 5 or so of the fleshy limpets in my 150. They came in on the live rock. About a week ago I woke up to a milky tank. I counted over 30 limpets spawning.
I have some of the same type as yours in my system as well.

I haven't seen any fleshy limpets that I know of but will keep an eye out. I've seen these hard shell ones in my tanks for years but usually just one or two when changing socks, never this many all together. I'm surprised because there really isn't visible algae in this tank except red coraline on the rocks.
