nightcrawlers

I have these… things seem to be active at night towards bottom of tank on some rocks. almost like red stringy hair . I guess it could be red hair algae but it looks different. Any help?

I've been using nightcrawlers for about six months with excellent results. I figure they're mostly protein so I still feed a mixture of crushed New Life Spectrum and other dry foods inbetween worm feedings.
