Worm/Leech Identification

[Dave P]

Hi,

I hope you guys can help. I was doing a water change and I saw two worm like things. When I google it I find some pics that look similar but I'm not sure. Some pics say they are leeches some say worms. I have fish and plants. Any help would be great.

With that speed, it's a worm. Leeches are slow (and most often the ones in our tanks come in on plants or live foods, and are detrivores). I'd guess it's a black worm-commonly sold as live food, happily reproduce in healthy aquariums. Most fish will consume any they can find.

Yeah, it looks like a black worm to me too.
