Ok, I have these really creepy worms in my plant tank. I bought a bunch of plants for my 55 gallon before I had it set up so I put them in a 2 gallon tank that I wasn't using and put it in my garden window in my kitchen. Well, the plants brought in a ton of snails, and I now have a lot of copepods, too. Then yesterday I got home from work and the sun was shining right in the tank and I was looking in at the snails and then I saw these things that looked like roots but they were moving. And I don't have a filter, so there's no current, so I took a closer look and they look like tentacles from a hidden creature in the gravel or something because they just slowly wave around and sometimes look like they're feeling around for things on the gravel. I know they weren't tentacles, but that's what they looked like and they freaked me out. I posted on plantedtank.net asking what they are, and someone almost right away said they're nematodes. but then an argument started between like 3 people saying different things. Nematodes and Planaria were the two mostly being thrown around. I dunno, though, because "nematode" is such a general term for so many worm-like things, and planaria have flat heads and these things don't have flat heads. They're also light pink. I haven't seen any of them swimming around. They seem to just stay in the gravel and stick out about a half inch or more to wave around a bit. They freak me out and now I'm afraid to use the remaining plant in my 55 gallon tank because I don't want to infest it with something weird. I'm also afraid to even put my hand in the tank, now. lol. Anyone have any idea what they are?? I will try to get a picture when I get home today, but because of the location of the tank, I might not be able to get a good picture of them.
