What is this????

[rodclement]

SO I am looking into my tank talking with Youpey abut his clowns...lights are out...and I see this dark worm coming from the sandbed...not a bristleworm but a dark brown worm about 1/4 inch in diameter, and with about 6 inches exposed out of the sand, it reminds me of an aneileide worm, like a common red worm...what can it be?

When I tried to scoop it out, it retracted into the sand and live rock...

Any ideas?

Check for photos of a eunicid worm (see the largest worm contest). Easiest to peg if you can see the head. That's got some pretty tell tale signature features (band, blah blah) smooth thing.

Take a look and see what you think!

I don't know, Try to take it out and contain it till you can id it. If you can they're quick

It's amazing what we can find in our tanks! When I was breaking down my 120 some years ago, I had time so I ended up soaking the rock in freshwater for about a week. When I emptied the barrel out there was a huge black worm, probably about 12" long...it almost looked like a bristle worm except it was black...YUCK!

looks like a harmless peanut worm.

I think it's a peanut worm, no bristles at all, I saw it many times last night but couldn't cath it...
Tell me about finding weird things in our tanks, i found an octopus in mine, I have a whole thread on another forum with pictures, craziest thing ever...when I took it out and re-homed it, it died within 2 days... :-\

Agreed, it looks like a Peanut worm, they are harmless. They will eat excess detritus (good for a reef tank).
