HELP: What are these
I am noticing small, about 1cm across "things" on my rocks and glass.
They are flat. White. Roughly round. When I clean the glass - they get removed, except for a ring of faint white where they were. I would say that they look similar to if I took a bottle of white out, dabbed the brush against a peice of paper, and let the little blob of white out dry. They are not "pure" white - but rather a dingy yellow white. They are perhaps 1mm high. They appear on the glass and on the rocks. Does anyone have suggestions as to where I could find pics of this animal/thing - and try to identify this animal? In particular - I want to know if they are pests, or good things. Thanks everyone! Kevin |

Not those.
These are flat in the center. Kevin Imagine a drop of elmers glue on a peice of paper. That is more what they look like. But only perhaps 1mm high in the middle. |

Hard to tell without a pic but sounds like baby snails to me. If you look veeeery closely you might be able to see the antenna

Here is a pic:
 That's the best shot I can get - you can see the white things on the epoxy there. |

I have the same things. I agree they are nerite eggs. If you use a magfloat to clean. It leaves the same faint ring that the original poster said.

Yep - Nerite snail eggs!
How long do they take to hatch? |

About four or five days maybe. Not really sure if you'll be seeing any baby snails anytime soon though. Our little microcosms might be a little to small for that, with the larval period and all. Keep your fingers crossed.
