Dead coral coming back to life?

[TangoTank]

I have a 75g FOWLR that used to have live corals. I pulled a piece of old coral as live rock for my 10g QT. I think I have an old brain(?) coral covered in purple Coralline... And since being in the QT it has a spot where it has turned really white (which I've seen Coralline turn white when it died (when I moved this used tank & stock, it died on the sides of the tank) but this isn't typical). The white spot is getting height! Could it be growing new coral OR can a coral come back to life?? This looks like bone, it's not soft/fleshy at all.

You know what our first question will be....can you post a pic?

Sounds like exposed bone. Once tissue from a coral dies and there is nothing left, there isn't any hope of it coming back. The only exception to this rule would be of course if there was still tissue hiding in there, which sounds unlikely from your description, or if it was a plate coral which have been known to rarely bud off new plate corals after death to save its genetic line...but this also isn't what is being described.

Here's some pics. Thing is, I'm not sure how much it'll show as pics aren't 3D. And it's just something I've picked up from observation. I tried to get it from a certain angle to show the growth. I'm just noticing the height due to looking at it all the time.

Not seeing a living coral in that picture.

Ok, thks. It just seems as though that white area has gained significant height pretty quickly.

Sounds like a sponge if anything.

I see fuzz maybe algae growing

There's definitely a ton of sponges growing, one in every nook! This is at the top, the white stuff & it's make the peaks/points seem much taller disproportionally than the other purple area peaks.

And yes, there's algae as well.
