Worms???

I've had this chalice for a few years now and I'm pretty sure that I've never seen this before. Are these some sort of worms? Is it an issue that I need to worry about?

Do you always keep sand on your chalice? Those are sweepers from the chalice, and it looks very irritated.

I'll use a powerhead to remove the sand. Thank you.
