looks like green hair algae to me. while it's not the end of the world (yet) it's not a good thing but there are many things that can contribute to it......... #1 reason is high nutrients (NO3/PO4)......... new tank syndrome.... improper spectrum lighting..........

Could be hydroids shooting off too. You can see what appears to be polyps circled. Should go away eventually.

I agree those look like hydroids to me.

Are they bad?

I thought maybe but idk if they are bad or harmful

Yeah I have had a problem with that but I am talking about the clear polyp things shooting off of it

They could be baby aiptasia, could be hydroids, really hard to tell. I wouldn't worry about it, but if that's the base of a kenya tree just cut it at the base and throw away the plug, it will survive fine

It’s supposed to be a neon nepthea, how do I get it to reattach to something?

A dab of super glue!
Alternatively a natural way to do it with nepthea, is placing the base (once cut) into some small rock rubble on the sand bed, give it a couple weeks and it should be attached to one.

Those can have a strong sting and tick things off.

Edit: If you just got it though I would wait a little while to frag it.

Its hydroids and best eradication is starvation. By aiming flow towards the coral, not at it, the hydroids will starve and disappear. They favor brine shrimp

Looks like algae to me just carefully scrape it off.

It's a type of hydroid

If they don't go away nepthea is a easy coral to frag. Would just wait a little if you just got it so you don't stress it out more.
