Looks healthy but it's PO'd about something. That colony has all kinds of stranges tuff happening. The white stuff is mesentaries, it's either injured or attacking something nearby. I think those crazy bubbles have something to do with it. If I'm not mistaken I think they sometimes develop bubbles like that if they are under too much light.

Man, I love Reef Central. Once again I am blown away by the service provided by this board in terms of providing a forum for the dissemination of info regarding this wonderful hobby.
Otiso777 mentions "mesenterial filaments". Having never heard of this before I did a quick google. I had been aware of "sweeper tentacles" for as bout as long as I had been involved in reefing. This is something else though.
" Mesenterial filaments
In addition to sweeper tentacles, several hard coral species can produce mesenterial filaments (also termed mesenteric filaments) from their stomachs. Corals of the genera Favia, Favites, Scolymia, Pavona, and Cynarina all have this capacity (Chadwich, 1987). These filaments can kill or devour other coral polyps through a process similar to digestion. Some corals even have the capacity to produce both sweeper tentacles and mesenterial filaments, enabling them to fight a battle on several fronts (Wallace, 1984).*
I would say this stuff is definitely coming from the shrooms stomach. At first I thought it might be some sort of very exotic looking discharge, waste that is.
The thought of it being a defense is brand new to me.
Ritten, that is not a bubble directly behind it but rather a kind of morph that this coral itself exhibits from time to time. That is, it is the coral itself.
Seapug, in terms of stress, the coral has never looked better. I had it at the top of my 180 at the back under 40 watt t5 sctinic and it did well. But now at the bottom under 14 k 250 mh it looks even happier.
So, the next explanation seems logical, something near it is upsetting it.
Hate to leave you all in suspense, but my lights have gone off and therefore I will have to wait til tomorrow to post a pic of the entire area nearby.
This was great, thanks for your help.

How long ago did you change the lighting and what sort of acclimation was done to this new lighting? Like seapug said, those bubble structures could be caused by too much light, or improper acclimation to higher intensity lighting. These factors also could be the stressor causing the discharge of the mesenterial filaments

Well,
I think you might have hit upon something here because I had neglected to change bulbs for quite a while.
And the shrooms have been bubbling ever since.
So maybe you and seapug are right because they are exposed to stronger light than they had been in the past.
I thought that having moved them down to the floor of the tank, the intensity would be a great deal less. But other mushrooms in my tank have never done that well, so maybe it is too bright even at the bottom.
Never thought of that. I have always assumed that mh 250 would accomodate acros at the top, and healthy muushrooms at the bottom. I think I was incorrect.
Again....
Always trying to learn. Thanks once again.
