I have a orange digita that has been doing great and growing base on my rock like crazy. I woke up yesterday and the base of the original coral is all white and all the polyps are in. The rest of the coral is still orange but no polyps. I am going to watch it to see if the white keeps spreading. Anyone know what is going on or what I can do to help it????? It looks like the polpys are completely gone where the white is.
I also have a pink digita which is fine but it is in the same area of the orange...I don't want to let it spread if that is what is happening.
I have some pics but they arent' that good.
Please help!!!!!

I had the same thing happen to one of mine. It look like RTN. I stopped it by using Superglue Gel at the edge of the infection. You could also frag the coral at the edge of the live tissue and mount it with so superglue to a plug or rubble rock. Also check your water conditon.

Good luck,
Martin

Honestly, something similar happened to me and I believe it was related to light. I had an acropora do that in spots for a while....after the white spots developed little black hairs appeared where the coralites used to be but it never spread to the entire coral. This coral was very near the surface and I always associated it with lighting since it never spread or anything. Good luck.

my M. capricornus gets spots on it sometimes that look like the skeleton is stripped of all tissue (like it looks in your pictures). It usually happens after it gets stung by another coral, or a piece of my E. glabrescens breaks off and lands on it. After a few weeks, the tissue usually re-grows over it.

It will probably be impossible to tell what irritated your coral to that extent.... if it continues to spread, I'd resort to the drastic measures like that recommended by Martin (super glue).

Even the encrusting part of the coral looks irritated to me. The frag in front of the coral looks withdrawn also. I would do a large water change and check calcium, alkalinity, and magnesium levels. Do you have any large leather corals or brain type corals with long nighttime sweepers?

Sompa, how is your Digitata doing?

do a good once over on your monti looking for tiny (less than 1/4") nudibranchs They'll be white or a faint yellowish in color with what looks like a little feather comming out of one end. Hopefully these aren't what you have, and it is a water quality/lighting issue, because the monti eating nudis are from what i've read a PITA to get rid of. good luck
