Worm I think

[clowninround]

I have what looks like a stringy worm (it moves around like one so I assume it is) but it is bright orange, any ideas?

I have a number of bright orange spaghetti worms. While planted somewhere most of the time, they occasionally pull in their tentacles and crawl around. These are beneficial tank cleaners, so I hope that is what you have.
