We have a medium size xenia colony. Today I notices that 2 of the stalks looks yellowish and is shriveled. THey are in different parts of the colony. I will try to take a photo and post it. I don't have Eric's book, yet. Where do I get it?

Eric's book may be found at a local fish store. Or, you can scroll to the bottom of any page and click the link to the RC bookstore and purchase a copy online.

How long have you had the colony? Xenia can be very sensitive to parameter changes, movement, and transportation.
 
Ok Thanks, I do have the book he co-authored with Ed Puterbaugh, and the coral book by John Tullock (also Natural Reef Aquariums) and haven't seen anything in there about this. We just got the colony on Wed, a great deal from our LFS. We also got a pompom colony there too that looks fine. I have other xeniae in the tank and they are small frags that are doing fine. When we first put it in, it may have gotten stung by a cataphyllia as we were placing it. It is on a rock that measures approx. 6x6inches. We have gotten frags in the past that were 10.00 each, and this colony would equal about 200 of those frags. It was a deal we couldn't pass up.
<Probably a Bad move> since our qt tank is cycling and won't be ready for another week, we did a 2 hour acclimation to our main 125. I checked all the water params last night:
Am=0
NO2=0
No3=0to1 on fastest, docwellfish shows 20 ?????)
pH=8.2
Sg=1.025 (refractometer)
alk=9.8
ca=400
PO2=.25 or less (it seemd to be between 0 and .25)
125gal 2 maxi400's, 1 Maxi 600 (3 on wavemaker),1 maxi 1200 on a spraybar, 125 to 150 lbs LR (we got it from a guy who was moving and selling a bunch of stuff for about .50 a pound, and it was marshallIs LR) 4to 5inch DSB, 20 gal sump, unknown brand of skimmer (used too) powered by a rio1700, quietone 4000 (very quiet, but sometimes hard to start) DIY: 2 coil denitrators, auto TO, Nilssen reactor, and waiting for the glue to set up on my hang-on fuge. We have some shrooms, poly's, zoo's, alveopora, cataphyllia, frogspawn (awesome colony),sarcophyllia, anthellia, yellowhead jawfish, royal gramma, lawnmower blenny, mandarin, 2 neon gobys, 2 cleaner shrimp, 4 peppermint shrimp, 40 or so dwarf hermits (bluelegs and scarlets),20 nassarius, 20 conch, 20 astreas, 20 other snails that I can't remember their names right now, 2 emerald crabs, a green brittlestar, and an electric scallop. Could something have taken a bite out of it? I am getting ready to cut off the bad looking parts and move them to my anemone tank. I have never seen this before and do not know what to do?
Thank you Jared for the welcome.This is truly a quality site with lots of info. Going to read some more now.
 
Update, last night I cut away the yellow stalk , it seemed to be "melting", this morning they look worse and we pulled them out of the tank. They are in a bucket of tank water with a powerhead. Getting ready to trash the whole thing.
 
You are sharing the fate that many others have experienced. Xenia seem to be very sensitive to transporting and sudden changes. Diagnosing a possible disease would be very difficult to do in person, and even more difficult online. It could be anything from the stress of transporting, improper acclimation, or even the possible sting from your Catalaphyllia could have added stress to an already stressed coral.

Sorry for the loss :(
 
My Zena just turned whit and shriveled up for about 3 days.. Then it started to fall apart... I have no clue why? Every thing in my tank is fine.. And all my Permeates are fine! So, Something happened but i don't know what.. Or it was it's time to die.
 
There was a great article about this in "Tropical Fish Hobbyist" Sorry I don't remember which issue, maybe you can find it on their web site www.tfhmagazine.com
According to the article, this is a normal cycle Xenia goes through. As a matter of fact, I just went through it about 2 weeks ago. Just keep doing water changes and try to get rid of the real dead stuff. If you are capable of keeping some clean and attached to the rock it is possible it will grow back in a couple of months. I had some real beautiful Blue Pulsating Xenia, some still survived, the snails help tremendously keeping the base rock clean where it was attached. Good Luck.

HTH,
Fredy
 
Update. Sorry I haven't updated sooner. On mon morn I took a ph and blew all the junk off the xenia colony and put the rock back into the show tank. There is only a smidged left. Saved some of the "hands" and put them into a frag container. Some are still alive and have attached to the lr rubble in the container. Kept most of the mess out of the DT. Giong to open the fragtainer in the morn and see what happens. From what I have found out from a few reputable LFS' that this is a common occurence.
