i just saw a worm in my substrate while i was vacuuming. should i be worried?

That really depends on the type of worm. What kind of substrate is it and how old? What did the worm look like? Was it alive or dead? And--just checking--are you sure it wasn't a fish poop? That could look a lot like a dead worm

i have an arogonite substrate and its about 5 months old. it was alive when i saw it. trying to get back into the substrate like i'd expect a worm to. it was an almost redish color.

I once had a small pinkish/red type worm looking thing in one of my old saltwater tanks years ago. I was told by my pet shop that they were harmless and fine, but if you notice LOTS of them, you should remove some.

well its only been that one, so i'll keep an eye out.

it sounds like a bristle worm google it and see if it looks same

If its a bristleworm, most are harmless - the small to medium sized ones. Most are just detritus eaters and will help the tank.
Its the big ones that you need to be worried about.
