Coral Disease Etiology???

[wade1]

I have a coral frag that is currently in the process of losing its flesh. This isn't RTN, this is a 'peeling' of the flesh from the skeleton, with the zoox fully intact. Here is an image of it, up close:

Anyone have any helpful thoughts? I've been told its possibly protozoal, although bacterial still is a thought. I removed the base it was from (the result of a frag trading session) and it and all of the small frags I made with it, have now been infected. Any thoughts on treatment?

Thanks!

Wade

Though your picture is great quality, it's hard to see the detachment occuring. The first thing that comes to mind is low calcium/strontium/magnesium levels. It is my understanding that they are all important in skeletal attachment. Most of the jelly infections I have witnessed are on Euphyllias and Catalaphyllias and necrosis progresses rather rapidly. The tissue withers away leaving an orange-brown glob. We've never done any pathology, so I'm just guessing that it's the oft-cited Vibrio in those cases.

If I was you I would try an iodine dip, this does look protozoal to me also, but this usually is a fast mover. How long has it looked like this? If you knew how to handle or obtain clorimephenical (sp?)this would probably also help it, although this is very toxic to humans and not highly recommended. I would also increase the current in this area, JMO.
