What the heck is this? A red macroalgae?

Some of them look like the second photo and some have a blue skin where the light hits with neon orange dots

Red bubble algae. Usually found on ocean sourced live rock. Not real common in dry rock tanks.

I have some too! It's called Botryocladia skottsbergii and compared to normal green bubble algae it grows slower in my experience.

Is it just in that one spot? What are your plans for removing it?
