What does a dying Goniopora look like

[reefer1970]

I have a large golf ball size green Goniopora that has not wanted to open much for the last few weeks. I Have a red one healthy as can be. Now there is brown fuzzy stuff covering it. I brushed it off out of the tank and it came back. is this normal death of a goniopora or is it that brown slime stuff I've heard about? Is it contagious and should I remove it ASAP? Where does it come from? I just had a die off of my 3 Xenias due to my lack of acclimation from my new Kessils- could this be related? Parameters all normal but high calcium and low DKH (7). recently added bag of carbon to sump

Is the goniin in trouble a lime green Stokeski variety? Your description is how they die and death is the rule & not the exception with this species. Sounds like brown jelly disease. Personally I would get it out and isolate it as many people say BJD is bacterial in nature.

Many of the red varieties are very hardy, like the ones coming from ORA.

Yes, lime green. If its brown jelly disease, are they more susceptible to it? And is it preventable?

This is a common way for them to go. The wild caught green gonis don't live very long in captivity.
