View Full Version : New Member - I have a question

Hi everyone,
I'm a new member, and I had actually found something swimming around in my tank at night. I thought it was worm of some type but I can't figure out what it is.
Someone told me to post the video of it here because the people on the forum would be a big help. :spin1:
So, here's the video, and I would totally appreciate if someone could give me an inkling as to what this dancing wormy might be.
Please excuse my language in the video. :o

Looks like some kind of epitoke, hard to know what kind though.

Not sure what it is, but if you had caught it, this is what it would have looked like:


Sucked it out of my tank.

Sorry the picture is blurry, but it was a PITA to photo because it was so small. One member said it could be the epitoke stage of a polycheate worm. I had two and one of my clowns, slurped it in, chewed it and then spit it out. The worm sank to the bottom and then recovered and burrowed into my sand.

Thank you both...
So what should I do with it?

Nothing. It's just the reproductive system of some kinds of worms. Hard to tell what kind in particular. My boyfriend saw one in our tank last night, and we don't have any worms that we have ever seen yet LOL. I guess we will soon!

The way it moved as it swam was interesting... Could it be some sort of ribbon worm? Let us know if it shows up again. Neat little critter.

EDIT: I couldn't tell from the video. Was it round or flat?

It was round.
It's actually shown up a couple of times. It comes out and dances after the day lights turn off, the first night I thought it would disappear after it went through the surface skimmer into the filter canister, but it came right back after a few seconds.
Then I saw it again the other night, so I thought it would be good to figure out what it is since it showed up after over a week

Very odd. Epitokes are part of worm spawning and usually a mass event. Even if you only had the one in the tank, a repeat performance seems strange. But I don't know much about worms. I did find this though:


The epitokes in that video swam with sort of a tail flipping motion. The one in your video seemed to use more of a full-body undulation. I'm only wondering because a lot of the swimming worms are carniverous and if it isn't a harmless polychaete reproducing then it might need to go.
