Wagon Wheels?

[Ziggy953]

A few days ago I posted a question in the getting stated section about copepods which my tank is teeming with, someone described something else in answering my question. I have a lot of tiny wagon wheel looking things attached to the glass, they are almost clear with a white center, too small to photograph (at least with my cam) I thought they were just feather dusters? Right? Wrong?????

Sounds like hydroids. Normally they aren't a problem and will die out over time. Somewhat common in newer systems.

Thanks Fluff, I'm doing some reading on hydroids now...seems you are correct! Thanks again!
