Depends what kind they are. If it's a coco worm: https://www.saltwaterfish.com/site_11...ot_parent_id=4
8-10". Most of the ones I have seen get about as big as your pic. I have Black, purple, white and pink so far. I've seen pics of green ones as well.
As for finding them in the sump, any number of ways they got in there.

In any case, not a bad thing.
