Happy Saturday reefers

I have a light purple branch algae that hitchhiked on my Feather Duster tube. I read somewhere that Feather Dusters don't like algae on their tubes however, something tells me this algae isn't harmful and perhaps even beneficial. Can anyone shed some light and/or ID? Any info appreciated!

can you add a picture under white light
 
Yes to white light.

Not sure who told you feather duster don’t like things touching their tube; I would be cautious about advice from that source.
 
That’s gracilaria parvispora also known as birds nest algae.
 
Love it. Would you suggest leaving it alone?
Can’t see a reason not to, although if it starts to grow fairly large you may need to trim it every now and then
