need help with a coral ID

[gtafanatic]

So i have been noticing these white tree like (stick) things growing from my coral, what is it? is it a good thing?

 

[Chrissy]

It looks like some type of branching sponge.?

 

[Trevor]

I would have to agree with Chrissy, never seen anything like that

the sponge is a sign that your tank is in good shape btw
