Red Flakes growing on Live Rock

[Illinijoe]

I have these red flakes growing on my live rock. I found a few things on the internet of what they may be but wanted to get your opinions. Please let me know what you think it is and if it is good or bad. Thank you!

In a fuge yes. In a display? Not really. But i tried to get some dragons breath red macroalgae to grow in my DT. It didnt take hold. Or the tangs ate it b4 it could grab hold.

A tang or just some snails will take care of it. Reds dont seem to be as invasive as greens. You might like it.

my fuge is covered in it all over baffles, pieces make it to DT every so often but never take hold.
