Some type of worm i think

ok so i have been noticing these worms in my sump and main tank they are long and thin a few inches long and covered with sand. the pictures are very bad cause the worms are covered in sand.

 

Probaly a type of Hair worm or spaghetti worm maybe.. but not sure cause it is coverd in sand.. But its in your sump so no worries..


Heres a link look for Polychaete-Cirratulid

Next time you see it uncover it from sand and get a look at its bodie.. that would deff get a possitive Id....

Oh and heres my second guess only because it is so long of a worm.. Is a Ribbon worm..
