Strange worm

[Landlocked]

While I was inspecting my tank a couple days ago, I noticed a strange black worm in the tank, hiding underneath a rock. The worm was black with rings of white stripes, and was only about 1/4 of a centimeter in diameter (thickness).

I couldn't see the entire length of the worm, because one end was inside my live rock, but I'd estimate that it's about 2-3 inches long. I could only see 1 inch.

It was hiding on the underside of my rock, and probing around in my gravel. Every once in a while the end that was sticking out would open, like the petals on a daisy would. It appeared to be doing something in the sand, but I can't tell what.

It hasn't done anything bad, but I just want to know what it is.

I've had my tank up and running for over six months. The inhabitants are as follows:

Two percula clowns
1 common cleaner shrimp
1 pulsing xenia
lots of macroalgae
1 small calcerous feather duster

Tank stats:
ammonia 0.25 (Barely noticeable, I can't get it to go away)
nitrite 0
nitrate 0 (or so close my test kit can't tell)

I can't find the artical I read with great info It was at reefkeeping to...
but the short of it was 99% of bristle worms were great, because all they eat is poo.

If you are concerned though here is a dyi trap artical.

I don't think that it was a bristle worm. It had no spines sticking out the sides, and looked to be very smooth. It seemed more like a tiny, eyeless eel than a bristleworm.

Do some worms not have bristles?

i have some thing similer did you find out what they are?

 

[Landlocked]

Not yet. It doesn't seem dangerous, it just probes at the substrate and gravel. It likes to stay in the dark, so I can't get a good picture.

mine are really tiny and there are a lot of them?

yeah i have similar worms. mine are really tiny and annoying looking. im not sure what color they are on top because they only crawl on the front of my aquarium. what are these things?

if they are really super tiny like 1mm-2mm and really squiggly, i had thousands of them for a while and i can't remember what it was (do an RC searhc on squiggly and you'll find the answer) but i believe it was a massive pod spawning. they were whitish, and 1-2mm, and hyper-active.
