So I have a 20 gal tank with angel fish fry that I probably over feed but I do a 50% water change every day. Today I noticed what looks like little white worms on the glass. I put some under my microscope and they look like hydra. I have never seen these in any other tank of mine. The tank is bare bottom with fake plants and nothing new has been introduced except the fry. Any ideas what these could be if not hydra? If they are hydra how did they get in there and how do I get ride of them? I need to move the fry to a bigger tank soon but would like to figure this out first. Now I wish I would have bought the camera that attaches to the microscope. Thanks, Mark

Not sure. Could it be mosquito larvae? I've seen that happen before.

If they're on the glass, they could be planaria, a kind of flatworm.
If they're planaria, you can look really closely with a magnifying glass. The head of planaria is slightly triangular.
Hydra has a main trunk and then 6 tentacles on one end. The other end is a sticky "foot" that they use to anchor themselves.
If it is hydra, they may be in other tanks but they're anchored to something that lets them blend in. Hydras reproduce by "budding," they pretty much clone themselves. The juveniles are really hard to see without magnification. So maybe one hitched a ride a while back and you're just now seeing them? All it take is the one and it can reproduce all on its own.

So I looked at them again under the microscope and I don’t know what else they could be. They have a long body with six tentacles at one end. So the question is how do I move the fish without bringing the hydra with them? If they came in with plants there’s a good chance I already have them in all the tanks but if not I don’t want to spread them around now. Thanks, Mark

Thanks, Mark You would have to set up a QT tank and start over. www.americanaquariumproducts.com/Aquarium_Disease.html#quarantine

Thanks, Mark Honestly, Hydra are not really a danger to fish but maybe the smallest of egg layer fry. Carl

They have a long body with six tentacles at one end. Yep, that's definitely hydra. None of the others have the little tentacles.

After I take the fish out will raising the temperature kill the hydra without killing the good bacteria? Thanks, Mark
