Long white worm swimming around

[cleaner72]

I noticed this morning in my 55 gallon reef tank, a long, about 3 to 4 inch, "worm", swimming around fairly fast in the water. He kinda corkscrews as he swims. I dont have a picture, but will try and get one this evening after work. It is fairly thin and white with what appears to be rib like features along the length of the body.

Any ideas?

that sounds nuts.

I've seen those before when I was trying to catch clownfish larvae in my main tank.
I was thinking that they were bristleworm larvae but have no evidence to that.

Sound like a really large epitoke. Cool!
