These things grew over night and I'm not sure what they are. The only thing in my tank that I just set up is live rock, live sand, and some copepods.

Here is the link to my pictures I took. It's onedrive https://1drv.ms/f/s!Amx1YsawsFvGrURAUGfotFPpC9L9

Welcome to R2R! It looks like you might have some aiptasia. You will want to kill it before it has a chance to spread.

That's bad? How would I go about killing them?

 

[Michael Naegeli]

Yes. Spread like crazy and sting the heck out of Corals. Get u some Aptasia x and follow instruction. Easy to take care of now. Few weeks could be a nightmare on ur hands
