They have flaps of skin that cover the shell. Sometimes it is visible though.

im pretty sure its a keyhole limpet. sometimes it will have a white patch on its back. They are harmless.

Stomatella, not elephant slug. You can tell by the tentacles extending from the mantel. They're like a mini-abalone. Harmless, beneficial algae eater that will reproduce readily.

That's a Stomatella, they come in the basic brown color and this black color. I have both kinds. They are my favourite snail, plus they are one of the few that successfully reprocude in our tanks.

If so, thanks for both the question and the answer - Because I have 2 of those hickhike with the rock when I bought some corals last month. I was really small and now almost about 1/2 inches. Still in there
