snail?

[Jim]

When I got home today, I saw what appeared to be a lot of eggs on the glass of one of my tanks. A lot of white dots about the size of a pinhead.

Upon further examination, it is snow white with a shell and two longish tenacles or antlers on the "head". There are crawling around (yet very slowly since they are so small).

I have attached a blurry picture (I need a macrolens). It is hard to tell much about it, I know.

google Collonista snail & see if that's it.

They are so small at this time that it is hard to tell. Their shells do not appear to be flat like the one you are refering to.

Collonistas look like tiny bbs (ball bearings).
