i got these wierd looking clear looking spiders that look like they are upside down hanging off of plants. i can't take a good picture.
Are they harmful? What the heck are they? they just hang there.

I haven't a clue but Yuck yuck ewwww. I'm sure someone much more helpful than I will speak up. I will just commiserate with you for now.

Possibly hydroids? Just a guess since I've only ever seen a few fw hydroids, that's what it sounds like.

I just spent some time googling it with no success. Keep trying to get a pic. In the meantime I will post for the mentors to see if anyone is familiar with this.

A pic will be very helpful.

Here is a pic of one I had in my tank. I don't remember them being a problem while they were there but being paranoid finally caused me to just toss the plant they were on.

I'm guessing Hydra. Do they look like little anemones?

If the picture that Fluff posted is the same as what you have, then it's a Hydra. Not a danger to larger fish, but if you have fry or shrimp it would be good to remove. I recently tried a medication that worked quite well to eliminate them in my Shrimp Aquarium, and it didn't bother the shrimp at all. I followed the directions in this article.
