I have the tank for about 2 months now. There are 3 tang fishes and a few coral.

Today I just notice that there are a lot of little black worms or something that looks like black little hair on the sand bed and all over the wall.

Would anyone know what they are? If they are bad parasites, how do I get rid of them?

Thanks,
Jaden

Without a picture it is hard to tell, but it sounds like cyanobacteria

It can look like worms swaying in the flow..... if you touch it is it slimey? Also if it's cyano it will come off the sand in sheets or globs.....

Google search "spaghetti worms" and see if they look like what you have.
