Tiny White sea apple?

I found this today, its about the size of a lima bean, round with a tuft coming out of the top. Any body have any idea? I know the pic is blurry but my camera sucks sorry

Look at some pictures of pineapple sponges. Just a stab in the dark.

actually after googling those sponges and taking a closer look at the two in my tank, I would have to agree its a pineapple sponge. So are they bad for anything?

No, they are common in new tanks.
