"Earth Worm" ID

[black_majik]

I usually don't bother with ask for an ID of a hitchhiker without a photo, but this worms description is very easy to explain.

I saw him/her under actinics

- Looks exactly like a earth worm
- Moves the same exact way an earth worm does. ( Stretches out to a spot and pulls rest of body towards the spot)
- Again under actinics, but it looked a little pink or grey ( matched rock color)
- About half an inch

This forum is so hard to work with. I never get answers or guesses

could be a peanut worm

Thank you for commenting, I'll check out a pic of one.

Typically, questions here get answered very quickly, especially in the case of worm and snail IDs. However, you have to understand how much diversity there is under the sea and how difficult it can be to ID the stuff from just a description. The differences are often in the subtleties that people just don't realize are important or don't notice. While "like an earthworm" may seem very descriptive to you, I can think of about a dozen worms or worm-like creatures that could fit that description, but none of them exactly.

I understand the ID situation, but still people an offer suggestions like tubeworm did and that may help me out

Hi, I actually have the same question. I have been looking for and ID for months. Not sure if this fits the description of yours , but could be possible. Yours doesn't sound like a peanut worm to me because when exposed to light they retract quickly and seem to turn outside in.

I will describe the ones seen in my tank as best as I can. They are almost impossible to get a picture of. (have tried) The largest one I have seen to date was close to 5inches long. I have been able to observe some of the smaller ones with an eyepiece. They are long and thin without segments. I would compare them more with a nematode. No appendages or antena. They also do not seem to get fatter as they grow, seem to stay uniform in girth while growing in length. I have seen a few burrow into the sand while others seek holes in the rock. They do not move fast and only come out into the open at night unless I feed my coral.

Not sure if that fits the description of your worm or not. But maybe it will help you describe it better.

Sounds like it. I haven't seen mine since the first time I saw it. Probably because its under 3/4 inch

Being unsegmented narrows things down a lot. My guess would be a nemertean or ribbon worm.
