Dying Xenia spiking ammonia       11/14/13
Hi Bob and crew!
 I've had Xenia flourishing in my tank for years...to the point I give it away! However, two months ago I put in a new protein skimmer (Seaside Aquatics CS6) and since then the Xenia have been dying.
<Mmm, well Xeniid colonies do go and go... then often crash/dissolve for unknown reasons at times. Perhaps the skimmer was somehow involved>
 By the way, this is not a problem to me:) .  However, I believe it is causing some issues. Two weeks ago I took out all of the live rock and chiseled out the xenia.  I've had either cyano or diatoms for a week. I can siphon it out and within two hours it's back.
<Yikes; no fun>

Also, I tested for ammonia and the results were 0-.25.  This was using an API kit which I have heard can give false positives. I did a large water change and retested. The result was 0 ammonia. My question basically is how do I stop the ammonia spiking?
<Stop chiseling and take a few big breaths... and try another/better test kit>

Should I just keep doing large water changes and wait for the biological filter to catch back up?
<Just the latter>
 Should I had Bio-Spira or some other bottled nitrifying bacteria?
<You could>
 Pertinent info: 80 gallon reef tank established 8 years. Livestock: 1firefish, 1 pink spotted goby, 1 mandarin dragonet and various invertebrates. Please let me know if there is any other information you may need. As always thank you very much! Jennifer

Re: Dying Xenia spiking ammonia; and Yellow "Coris" (Halichoeres) hlth. follow-up     11/15/13

Dear Bob,
Thank you, thank you, thank you! I feel much better:)  I will definitely get a better ammonia test. I've always had a hard time reading these;)
<See WWM for recommendations here, and actual users input on bbs>
By the way, I recommended a fellow reefer get your advice on a Yellow Coris Wrasse that had a growth protruding from the gill.
<Yes; I saw, responded to this... tumorous growth am guessing>
 He took it to an aquatic facility near him where a marine biologist attempted to excise the tumor.
<Umm, I'd suggested leaving it alone; perhaps trying some purposeful biological cleaners>
The tumor had eroded the gill plate and had grown up to the back of the eye. Needless to say the fish did not make it through the surgery but the prognosis was not good anyway.  Jennifer
<Aye. Thank you for this follow-up. BobF> 

Red dragon Flowerhorn. Hlth., likely env., gas...      6/9/13
About 3 days ago my female red dragon fh which i have had for 5 years got sick like never before. She is and has always been in my 75 gal tank with a canister filter rated at 420g/h bubbler with 3 stones in tank 400w Heater. The temp has always been between 84-86
<Too high... I'd lower to the mid to upper 70's F>

blue background river stones and many caves. She is with 2 jags a midas cichlid and 2 convicts all between 4 and 7 inches she is about 12 inches. I have basic tests for all parameters nitrites read between 0-.25 but closer to zero ammonia is 0 and ph is 7.5 nitrates are close to zero. I woke up and my fh was looking right at me (tank is right next to my bed) breathing heavy and being very lethargic. I have a good relationship with my fh and even on a prefect day she will let me catch her and remove her from the tank so i examined her through the glass and saw nothing. Then grabbed her and pulled her out. Looked in her mouth through her gills inspected her fins and saw nothing. Her last stool was a normal reddish brown. I replaced get in the tank and she was still the same. Throughout the day her condition worsened breathing heavier and laying around with no will.
<Sounds/reads like a gas exchange issue/problem... too little O2 and/or too much CO2... too low gas solubility in too small a volume at too high a temperature>
 I did a 50 percent water change
and later noticed she is holding one gill open and relying on the other one. What could cause this to happen?
<Environment most likely... and that the largest fish is mal-affected... the above>
I believe her gill is infected somehow but with no fungus or ick swelling or anything. Only thing i can see is a patch where the skin looks washed of color which had always been lighter and could just be more noticeable because i never see her so black and dark colored. I put her in a 45 gallon hospital tank that i keep set up with prospects for my 75gal i tested it everything is good just don't want the infection spreading to any other veteran fish ill risk the newbs first. I treated both tanks with "triple sulfa" anti bacterial fish medication.
<I would not do this. Will only worsen the cause of this trouble>
 And tetra parasite guard.
This was yesterday she is breathing a little easier
<Due to your water change>
and is off of the bottom but gill is still stuck open. Like half an inch open and not closing at all. What could it be and do these medicines seem right?
<No more "medicating"... wick off the top water every day for a few days, be careful/stingy w/ feeding... Keep up with the weekly massive water changes. Shop for a larger tank... Bob Fenner>

Caulerpa and Xenia  10/26/11
Dear WWM,
<Hi Charles>
I'm trying to figure out why my entire colony of Pulsating Xenia is dying.
The only thing out of the ordinary (water quality - husbandry) was that about three days prior to the Xenia starting to show signs of distress ( less active pulsing and "fluffy-ness )
<How long have you had the Xenia before this started happening?>
I did a large pruning of the Feather Caulerpa I have. (some in the main tank and some in my refugium ) I know that Caulerpa release a Toxin when pruned / broken, but since I always run carbon (Chemipure elite) and did a water change right after the pruning, I didn't think it would be an issue.
Now, my Xenia are all retracted and the "feathers" are literally becoming goo. This is about 1 week after the pruning...
Could this be a result of the Caulerpa pruning, or should I not be pointing fingers at the algae and keep trying to track down another cause?
<Not likely>
All my water parameters haven't changed, lighting, feeding, nothing ...except my Xenia are turning to goo. (not the stalks, just the feathery fingers)
<Including parameters in email is helpful; check pH, iodine level or maybe even fish culprits that might be nibbling on Xenia behind your back. Lots of useful info here http://www.wetwebmedia.com/xeniiddisfaqs.htm>
Sincerely, Charles Paskey
<Happy Pulsing, Michelle (Fichecake)>

Blue Xenia Color Fade...But Polyps Otherwise Healthy and Reproducing Quickly -- 11/08/10
Hi gang,
<<Hello Chuck>>
My question involves some blue xenia... I have received starter colonies from a friend who grows these things four or five times over the years. I always experience the same thing -- once they hit my tank, they acclimate...start pulsing... and reproduce quickly, doubling in size over the next month or two. But they also lose their bluish tint.
This last time, with five or six colonies at different heights, proximity to my lights, etc. seeded in various places in my tank -- basically anywhere the current wasn't too swift to beat them up, all faded at the same rate...blue/gray totally gone after about two months, and now are beige/brown.
<<Almost certainly environmental -- and likely the "chemical" composition of the environment (bio-mineral and/or nutrient content)>>
I use metal halides... No actinics at the moment... But I had the same experience under a PC 50/50 setup with blue and purple actinics in my last tank's lighting setup. Is there some additive I'm likely short of that would cause this?
<<Almost certainly this is the case>>
And if some sort of correction is made, am I likely to ever see the 'blue' again?
<<Possibly'¦ You should start by examining the friend's environment and husbandry practices of the system in which the parent colonies are maintained. Query this person re any additives, the specifics of the system chemistry (pH, Alkalinity, et al), even down to the brand of salt mix and Salinity/Specific Gravity>>
Thanks in advance for any help on this...
<<Happy to share'¦ EricR>>

Strange Happenings/Xenia Health 10/16/10
<Hello Dave>
hoping you can assist, I have a 150 gallon reef tank which was growing Xenia and spreading throughout the tank at a awesome rate, all was fine until the weekend when I was forced to remove a large Fox Face Rabbitfish, for months he was fine and all of a sudden he began to bite the heads of the Xenia. After removing him the Xenia appears to have stopped growing, they are not as tall as they once were and they appear to be docile or sleeping all day with the flowers staying small with the odd one opening up , any suggestions would be appreciated.
<Xenia crashes can and do occur in colonies that have been doing well/reproducing without any apparent change in conditions. Seems as though they have exhausted some special element in the water that we
do not know about. Is weird/strange. Quite often, after a meltdown, Xenia will often come back within a few months as some tissue is always left behind.
What may help you more than anything is to slowly raise your salt level up to 1.024-025 over a one week period, 1.016 is a little on the low side for these animals. Have you recently added any aggressive corals such as Euphyllia?>
pH 8.3
Phosphate 0
Salt 1.016 <<Way too low. RMF>>
Temp 81
<You're welcome. James (Salty Dog)>

Re Strange Happenings/Xenia Health 10/16/10 - 12/7/10
Hello me again
<Hello Dave>
with another Xenia issue which just occurred yesterday, two small Xenia plants <plants?> separated from the rest of the larger group was doing fine with some others, however yesterday morning they just died, like dead, they shriveled up and the crabs are picking at them, not sure what occurred??
<Mmm, read original thread again.>
The ones that died were right beside others and they appear to be ok today, the rest of the main coral bunch appears to be fine, is there something I can do to ensure this does not happen to the other corals?? The salt I have adjusted after your last recommendations to 1.21
<Mmm, I recall suggesting 1.024-1.025, look below to original thread.>
and this has help them to appear to be growing and thriving, I am doing water changes every week about 5 - 10 gallons and have charcoal bags hanging in the sump changing every 2 weeks, I am also feeding them by syringe small doses of shrimp and they look like they are digesting them.
<Will not eat particle foods. I would discontinue the use of carbon, see if that improves the health of your remaining colonies. It has been said that Xeniids depend very heavily on dissolved organic compounds as they are found in areas of high nutrient levels. The use of carbon will remove a large percentage of DOCs thus lowering their food supply. Overdosing of iodide/iodine will/can also cause problems with Xeniids. May want to read the FAQs found in the header on various Xeniid topics.
Thanks for your time
