Penny Posted February 19, 2021 Share Posted February 19, 2021 Hey all.. I'm hoping someone could help me identify the worm type things that have appeared in my tank... Theres quite a lot of them on the glass. They're tiny, 2mm long and a bit thicker than hair but not by much. You cant really see detail on my pic but they're long and thin.. have a end that's definitely the head end.. the move by contracting and stretching and they have a thicker section in the middle. My tank is a 27 gal tall 6 neon, 6 cherry shrimp, 6 Cory's and at least 6 cory fry. All inhabitants went in two weeks ago and the fish shop said they all been quarantined for the last month to 6 weeks. Any help is greatly appreciated Link to comment Share on other sites More sharing options...
Fish Folk Posted February 19, 2021 Share Posted February 19, 2021 Well, the two most common candidates would be Planaria, or Detritus worms. Planaria scoot on the glass like a fast-moving slug. Detritus worms wiggle wildly like out of control water snakes. But your image looks like something else maybe... some sort of nematode? 1 Link to comment Share on other sites More sharing options...
Penny Posted February 19, 2021 Author Share Posted February 19, 2021 Ooh.. thank you.. they're definitely more fast moving slug, than out of control water snake (awesome descriptions btw) but it's more like a leech with that 'stretch and contract' movement. I'll have a look at nematodes. Thanks again Link to comment Share on other sites More sharing options...
Brandy Posted February 19, 2021 Share Posted February 19, 2021 Hmm, I have seen similar I think, but not sure what they were either--other than, in my case, FREE FISH FOOD!! Hopefully the neons notice them soon. The reason I have no idea what they are is that I no sooner noticed them than the fish did and they were just gone. 1 Link to comment Share on other sites More sharing options...

I've noticed at least three different kinds of worm in my tank, but they are hardly visible with the naked eye. I wish I knew more about what exactly they are myself. I think the one in the video above has a similar blobby end and pointy end. 1 1 Link to comment Share on other sites More sharing options...
Aubrey Posted February 19, 2021 Share Posted February 19, 2021 I did some research to find a name for what I shared a video of. If you you have what I have then they are called Aeolosoma. 3 Link to comment Share on other sites More sharing options...
Penny Posted February 19, 2021 Author Share Posted February 19, 2021 Great work @Aubrey That's exactly what it is. Thank you so much And these are fine to be in there? As cute as that little guy is in your video, I do hope they're some free live food! Link to comment Share on other sites More sharing options...

I imagine I would have heard of what they were called or it would have come up easier when doing a search if they were an issue. 2 Link to comment Share on other sites More sharing options...
Barqs Mom Posted February 20, 2021 Share Posted February 20, 2021 Thanks for the heads up. Yes, I had them too. They appeared about a week after I set up my 40gal. I'd added a large piece of a waterlogged tree branch I'd picked up along the Columbia River, not too far from where I live. I'd boiled it in a huge stock pot for 6 hours and then put it in my oven at 200°F for 4 days. Anyways these worms started showing up after I'd planted a bunch of live plants, rocks and the tree branch. I got rid of them by adding 2 generous tablespoons of Hydrogen Peroxide to the water. Yep it killed them, but didn't harm the plants. 6 weeks later I added 4 more plants bought locally, and 3 tiger barbs ($0.25) sized ones to the aquarium. Today while feeding them I saw more of these worms on the glass, some in mid-water. So if it's true these worms won't harm my fish, I won't quarantine them while I kill the worms.

I will keep you in my rolodex should I have an ichithyological mystery. 1 Link to comment Share on other sites More sharing options...
