Worm ID, came off during dip

[skylan]

Trying to figure out if I have a problem or not. Have some frags I was going to move from QT and this came off in the dip. Shown on slide w/o mag and on the lowest mag setting (40x). A second worm is shown head and tail with a nice dinoflagellate for size reference :(, would appreciate any help I could get. Was thinking the first is Dorvillidae.. I have no idea on the second. Thanks! Attach files

Do you have a picture of the whole worm? It appears to be a harmless euclid, however, I'd need to see the whole worm.
