HELP! I have these tiny, thread size white worm thingy's on my tank glass. What are they and how do I get rid of them without harming my oto's and cherry shrimp?

Thanks in advance guys.

Most likely it is either planaria or nematodes. They are harmless. Normally caused by excessive feeding, excess organic matter, or poor substrate cleaning. They are unsightly and disgusting to me. I got them in a fry tank one time. I cleaned everything very good. Vac the substrate really good. Cleaned the filters, replaced the disposable media. Wiped down the glass on the inside. Even with all that I still see one every once in awile.

Ok, thanks sfcallen. As long as they are harmless I will just try to slowly rid the tank of them manually.

Sorry Spypet, I wasn't sure which place to put the post. I will post once in the future :D

And thanks suzieQ as well

We just had an outbreak of these guys as well.. Only it was in a new tank that was still cycling. There wasn't any food for them in the tank yet!

So don't think your overfeeding or doing something wrong.. it may be something else that stimulated their growth. :cool:

You must of transfered them in from another source....filter media, substrate from another tank, plants from a tank that has them, some possible source of cross transfer. Planaria or nematodes don't show up for no reason.

It is a theory that Planaria can show up from flake food or other fish food sources. That part of their life cycle can be a dormant cycle, waiting for a wet opportunity. I believe this, as I have had them show up from over feeding and no other source.
