Aloha all. Very new to the hobby, and first time doing reef aquarium. It's not actually my tank, per se; I got it for my sons 6th birthday at the start of August. I decided to grab new live rock, as the ones I had were white as I was trying to use boiling water to remove the aiptasia's and dropped the container of boiling water right over them, plus the last week, they ended up being covered in green algae, even though levels were fine. After cleaning tank, water change, etc., placed in the new live rock and noticed this:

Any idea what it is? I don't think it's a auptasia, but then again, I could be wrong. If it's not, is this a pest that I need to remove some how? Thanks.

Yay. Feather Duster.

Thanks, Dave. I thought it may have been a Feather Duster worm after reading something this morning. Good to know it definitely is. All been a big learning curve for me. Need to find someone close by with experience that can check things out from time to time.

And are these little two auptasia's?

If so, what is the best home remedy? Just try shooting boiling hot water at them in the tank? Thanks.

I can't tell from the photo, they could be. I have have heard hot water works but never tried it.
The commercial options work well, 90/95% of the time on first dose.

Look more like brown paly to me.

No, they are not Aiptasia, they are Zoanthids/Palythoas. I would keep both, especially for your son to watch grow! I would avoid boiling water on anything. It kills too much good life, compared to what it kills. I would instead target kill the Aiptasia by pumping them (using a syringe) with freshwater, or turning off your pumps (just for half an hour) and cover them with AiptasiaX (should be able to pick this up online or at a more marine dedicated LFS).
