Can anyone tell me what these are?

I noticed these today. Have no idea what they are. They move, have tentacles and look like snails without shells or slugs. We have 3 snails in the tank. Could they have reproduced?

Thanks-jendiver09

stomatella snail. They are harmless.

Where do they come from? The tank has been up since may. We haven't added anything in the tank since July and just saw it today.

They come in on the live rock I have them in my tank normally see them at night you will see all sorts come out of the rock over time.

Keyhole limpet. From what I know they are good to have.
