Please ID this horriblle Killer

[Keith Russell]

This morning when I went to work my Duncan and this superman mushroom were fine. I stopped by the house at lunch ad saw this. Please help me and ID this mess and help me with a plan of action. Everything else on the reef is fine.

I don't know why the images are sideways. Sorry for that.

Looks like a sponge

What corals do you have near it? Have a picture of whole tank? From pictures looks like they may have been severely stung by sweepers

 

[saltyhog]

Is this the predator or is this what's left of your shroom?

The larger blob was a Duncan Coral with about 10 heads on it. The smaller blob was a superman mushroom about the size of a silver dollar. Here is a image of what it looked like 2 days ago. dang this one is upside down. Its between the two polyps. by the Favia

Oh it looks like that favia is taking them out. I agree with coral warfare.

 

[Keith Russell]

It looks closer than it really is. How far can their sweeper reach?

 

[sfin52]

Before dino took out most of my tank my favia went 4+ toward a duncan

6+"

Favia if angry can get 6+" sweepers going and they will whack anything they do not like. I had one get close to 8" sweepers once to take out a hammer near it.

I must be blind! Where is the duncan?

I meant in the before picture. I see the Superman shroom, but I don't see a duncan anywhere?

Culprit looks like the favia. While their feeders don't not extend at a distance more than an inch, they can do some serious damage. Relocation the surrounding coral or the favia itself is your best bet. Additionally, lights look a tad bright. Run whites at39% max and blues about 64% and you get earn some nice colors from the coral.
