White hair coming out of frags, what is that ?

[M4rtin]

I have two frags that came from one supplier, one is acan the other not sure
Both are getting white hair coming out of stony part of coral.
They're getting longer, and not sure what this is.

Are they soft or hard? My first though it sponge of some sort, or tube worms.

Very soft.

Sponge

Sponge agree with I do.

 

[M4rtin]

And what is said sponge ? Invasive, will it mive to other frags ? Is there way to get rid of it or it will die off ?
Any extra help would be great.

Sponges are generally a sign that your tank is doing well or starting to mature. I would leave them be I've got these as well

Thank you.
I got first fish in, sixline wrasse, and he picked the frag clean from those hairs.
He already proved himself usefull on second day

If those were sponge, they were unlike any sponge I've ever seen. Since the wrasse went after them, I'm going with something meaty but my first inclination was some time of macro algae.

He is the first and only fish that will be in this tank.
