You talking about the harmless "limpet" right at the top of the suction cup where it sucks to the glass?

That yellow snail on the left looks like a Conch or perhaps a predatory Whelk and the one on the right is a harmless Limpet. You might want to remove the yellow snail though just to be safe and take some pictures of both the top and the bottom of the shell. Post these in the Other Invertebrates Forum and pagojoe should be able to identify it for you.

They are limpets indeed, but what is they're purpose or what do they do? Just curious. For the snails I thought they were young sand sifting snails from the eggs I've always seen but you have me curious I'll post something there soon

yeah the snail looks like a harmless nassarius to me..

A limpet is just another algae grazer/eater..
