What is this white stuff?

[SoulFish]

I'm in the process of moving a few live rocks over to the display tank, almost all my corals have died. Yup basically lost everything due to the temp tank not being good enough, and another issue I will not bring up publicly.

Anyway this is my last coral, and it now has this crappy white stuff growing on it. IS this something I need to worry about getting into my new tank?

I have no idea what that is but I'd be interested to know too.

looks like a sponge I have in one spot on my LR which I've also seen on the LR in a friend's tank, never seen it grow on a Coral before!

Is the white stuff like "snot" or more solid?

 

[SoulFish]

More solid, I cannt pull it off. It's soft, but firmly attached to the rock/coral. It almost looks web like

Here are some more shots

Good. Snot like would be a bad sign.
My guess would be a sponge or a tunicate. Generally not a concern.
wetwebmedia has lots of pictures and information on both. You might find a match.

looks like a sponge to me.
no worries i would think unless it starts chasing you around the living room

+1 on sponge.

Why is 'snot-like' bad? What would that indicate?
Thanks in advance for the info.

This might not be the most conclusive answer but I've seen a ball of white snot form around something after it dies and sits there for a while and begins to deteriorate.

I just rip or chip them off, I had those grow over my Z's and P's.

I was mostly thinking Brown Jelly disease, but looking more at pictures, not really a match at all.
There is also a "white reef slime" that looks similar. But I think that is super rare.
Both are bacterial slimes, hence the snot like appearance/feel.
