Just different types of pods. No real big deal. They are harmless.

They're spirobid worms to be exact . Type of tube worm but like melosu said they're harmless and beneficial

These guys come as a phase of under a year old tanks and will eventually fade away until they are all gone. I was caught off guard by them when they showed up in my tank. They are all gone now.

My tank is a year old but I still dot have all the right lights for coral and stuff could that play a factor in it

Nope. It's a phase that happens in the first year at some point.
