    I have a weird white growth under this rock. Looks greyish white and is spreading through whole rock. In pic, right behind Hawk's tail.
    Any idea's? Should I be worried?

    No one has any ideas on what this might be? Or should I do anything about it?

    Looks like a sponge to me, looks to be safe for your tank, I wouldn't worry about it.

    That's sponge. I have this stuff blue and white in my tank. They're beneficial, filter feeders on dissolved organics.
