Should i be worried?

Hi everyone, i am new to having a reeftank and after a couple of months waiting for the tank to cycle some tiny worms started to show up and are now forming some kind of colony.

I tried searching for them online but couldn't find an awnser if these worms are good or bad for the tank.

Welcome!

I personally wouldn't be to worried about them. What size tank do you have? Do you have any fish in it yet? Some will make a meal out of those worms.

For a brand new cycled tank I wouldn’t be worried, looks like some sort of algae film that latched on some micro bubbles from your filter or skimmer and got stuck to the side of the tank. How’s is all else, anything else a particular color or noticeable dying in the tank?

Scrape it out dude. You’re a very effective member of your clean up crew. When in doubt SCRAPE IT OUT lol

They're harmless little polychaetes (bristleworms) of some variety - I haven't been able to nail down an ID on them, but they show up every now and then. They don't cause any issues that I've seen, and the colony behavior they demonstrate is very unique.
