Green macroalgae good or bad?

[vector_int_fish]

In addition to the redmacro I have growing I also recently had some green ones show up too. If possible please help me with identifying them. thank you.
the first photo has two different types of macroalgae, one of which i think is some type of caulerpa. The other fans out like a fern. The second photo has some sort of algae that is round and looks like a group of green fingers. please help if you can. thank you.

Is there anyone who can help me? or atleast might have any idea on what these could be?

First one is bryopsis, remove it asap. Turn off pumps/powerheads, and scrape and siphon as much out as you can.

2nd one looks like a form of bushy chaeto. Shouldn't be too invasive as long as you keep it under control and don't bust it up into a bunch of pieces.

Thank you for the reply Vilelent. With regards to the bryopsis....is there any fish or invert that will eat it?

As far as fish go, if you trim it down, Lawn mower blennys or Starry Blennys will graze on it, my Starry would munch at whole clusters of it when I used to let it grow in its previous tank. When its in its full leaf form though, nothing seems to fully eat it as far as I have experienced, Even big turbos seem to just run over it, unless its short, then they will eat at it, Astrea snails will eat it too, and Trochus snails. Worse case, if its just in 1 patch area, you can trim it down manually and suck out the excess, then apply aptasia X to the spot its on, cover it up completely, leave it for 15 minutes no flow or powerheads on. I've had success killing alot of nuisance algae using aptasia X, seems to penetrate the algae and kill it.

First one is very hard to see honestly... Might need a clearer picture

Second looks like Caulerpa var peltata
