Just saw this tonight while the coral was shrunken. I have noticed no ill effects of anykind on this coral so I'm confused to all of a sudden find this dark, black-like, growth on it.

Any ideas?

I can try to get better pictures if needed.

Interesting.
It looked more hard and non-porus to me, but that's still makes me wonder.
I'll try to get some better pics tonight to put up here.

Finally did closeups. and you're right reefgeek84, it's a sponge.
Albeit not a pretty one, just kind of black.
I'm pretty stoked though since it's my first sponge, I've never purchased one so it's a hitchhiker.

Couple questions regarding it...
Is this just considered a black sponge, or is there a more appropriate name for it?
Should I move it to another location?

I had them before and they are called black sponge. The only problem is that they are good for the tank but can be envasive toward all other coral. That's why I took mine out.

Wow nice sponge man, maybe you can relocate some of it if you decide to move it

Thanks for the help! I'll manually pull it off and attach it to a piece of LR.
Anyone happen to know the scientific name of it so I can do a bit of research?

Most sponges are pretty much impossible to identify unless you're an expert in the field and have an actual specimen to work with (and usually questionable even then). You can't really go much farther than to say this is a demosponge, which doesn't narrow things down much.
