Any idea what these are?

I found these in the tank last night. They look like snails without shells to me. Is there such a thing?

What do you guys think? There are 2 black and the one brown that I have found. Good or bad?

That would be a black stomatella.

Cool critters, harmless for the most part.

Have a read about them here:

I must have brave ones. They are always out and they eat ALL the unwanted stuff. They are even brave enough to graze on my heater. mmmmmm...escargot...... :p
