Glued The Top Of My Xenia While Fragging/Xeniidae
Hello WWM, hope everything is well and thank you for reading this,
<Hello Peter, and you're welcome.>
I have a question about what to do. Firsts of, I was fragging some
mushrooms and Zoas today. While I was fragging those, I decided to go
ahead and re-frag a xenia frag to a different location because my
mantis shrimp liked to use the rock it was on to cover his entrance
burrow. I was being careless and after I fragged some Zoas and
mushrooms, I started to glue the xenia to the back of my aquarium. I
did not notice that I still had glue on my fingertips and I
accidentally glued one stalk top of the xenia permanently open.
Thankfully it was only one as it could of been much worse. But my
question is should I
cut that stalk off that has been glued? Or should I just leave it be
and hope the glue wears off? The glue is CorAffix brand gel. It
doesn't seem that it will come off by itself.
<I would just leave be, the glued polyp will likely
Thank you once again and have a nice evening!

Pulsing Xenia "hands" missing
Hi there. I have a Pulsing Xenia that I got from a LFS. It was
thin and tiny when I first got it. I noticed that around a few of
the "hands" there is a white spot and there are a few
<Mmm, you may want to remove the white spot... or take a
large, well-resolved photograph... "blow it up" on your
computer and look... This could be a pest, likely a Nudibranch
The tips where the hands are missing are white. It is still
pulsing and little hands are still growing out. I was wondering
what is causing this.
<Use the search tool, http://wetwebmedia.com/Googlesearch.htm
with the string: xeniid+predator
read the cached views with the highlighted string>
Do they propagate this way or is there a predator that I have not
<Likely the latter>
It still looks healthy though. I have it on a frag shelf up in
the upper part of the tank. So I am not sure what could be
bothering it. I have 2 clowns, 2 orange lined cardinals, snail,
<Could be these>
and some corals. Corals are mushrooms, toadstool, star polyp,
frog spawn, and some Zoas. I have another question. My Pom Pom
xenia is not pulsing.
I have had it only 2 weeks. What causes them not to pulse.
<... see WWM re>
I got it from LiveAquaria. If you need anymore information let me
I would appreciate any help. Thanks you guys are the best.
Pulsing Xenia "hands" missing with
I have a Pulsing Xenia that I got from a LFS about 3 months ago.
It was thin and tiny when I first got it. Now it is much fuller.
I noticed that around a few of the "hands" there is a
white spot and there are a few missing.
<I see in the pic... maybe the Acanthurus leucosternon here
I know Bob said to cut out the white spots but as the picture
shows it is right below the hands and there would be little left.
It is as if the hands are slowly constricting and then falling
<Oh... then could be a chemical anomaly... as alluded to
previously. Did you read where you were referred?>
I have looked for a Nudi and have not seen any. I also have been
looking for any movement around the rock. My hermits can't
reach the rock on the shelf. The one inhabitant I forgot to
mention is a pincushion urchin.
Could this be nibbling?
But wouldn't it just bite them off? I am willing to cut but
am afraid there would be no hands left ;). Again any help would
be great. I hope the pic helps. It shows the xenia on the shelf
and you can see the white areas before the hands and even some
where the hands are missing. This is why I thought maybe it was a
reproduction thing. I am at a loss. Thanks a million. The website
Re: Pulsing Xenia "hands" missing with
I don't have tangs.
<Ahh! The pic you sent has something suggesting this>
I only have 2 clown and put in 2 cardinal after quarantine (This
started before I added the cardinal) I was told it might have
been a predatory Nudi.
<... as I originally stated...>
I have been reading about predators and xenia.
I have been looking. But have not seen anything yet. What
do you think?
<... please stop writing, and read>
I have been reading other xenia info as well. Thanks for getting
back so quickly. Sorry I am being a pain but just a little
confused. I don't want to have my xenia have problems. I love
All My Polyps are Closed!!? Anomalous Xeniid
I have been a big fan of this website for years, and I come here
whenever I have an easy or tough question to answer. The wealth of
knowledge on this site is second to none, and I appreciate having this
Here's my most recent issue:
I've had a reef tank set up for a little over 3 years (50 Gal
display with 30g sump), with various polyps, and other soft corals, as
well as some fish, snails, etc. Everything has been doing well, but I
recently switched two things to my tank, and ALL my polyps have been
closed since. It looks like the Pom Pom Xenia are all either dead or
dying, as well. I'm hoping someone can help...
<Do be ready to scrape, remove the Xeniids if they're
collapsing... or take out all else to some other system>
I have always had perfect levels (8.3, 0 nitrate, 0 phosphate, 480
cal., etc.), but was still having an algae issue. To combat that, I
decided to add a Vortech MP10 to make sure I didn't have any dead
areas (Have been running a Mag Drive 12 as main return with a SCWD,
with a Maxi Jet with 1600 attachment in the tank). I also added two
boxes worth of Hagen BioMax Filter Media in a section of my sump, just
before the return pump.
<Both these changes, additions should be fine>
My goal with those was to get rid of any "crap" that kept
getting pumped back into the main tank by the return pump. My levels
are still pristine, algae is pretty much under control, and the clarity
of my water is much better.
But, my polyps remain closed!?
<Something else... but Pulsing Soft Corals can/do at times undergo
population collapses... and the resultant chemical stew can be very
toxic to other Cnidarians, fishes even>
Have I "purified" the water too much with the BioMax?
<No... this is a chemically inert material... for bacterial
I've tried different speeds with the MP10, and no change. I've
also tried putting Coral Frenzy in a few times, and no change.
Any help is Greatly Appreciated.
<Again, the removal of the Xeniids... or all other livestock
elsewhere... Water changes, use of carbon, spiffing up your skimmer can
only do so much>
(if this helps, I also have a small amount of carbon filtration, Nova

saltwater tank I started with a small xenia frag and it after a while
began to grow quite rapidly and spread out, I was able to cut it apart
from the original frag and moved the frag elsewhere, it was doing
great. I then developed excessive phosphate (red slime) and was forced
to treat the tank with a remover chemical twice,
<Not the route I would have taken>
during the time the xenia seemed fine and full of life.
The day before a water change was due I fell and broke my back,
<? VERY sorry to hear this..>
so was forced to call on some aquarium techs to give the tank a once
over which they did.
<Yes, of course>
Only now the xenia although moving in the current is not moving the
hands and they look like they are stiff and at times curl up in the
day. Are they sick?
<Maybe not sick as such, but they do this when something is not
right, chemically with your water, irritating the coral>.
What do I need to have done to help them.
<Run some carbon pronto. Make sure the skimmer is on. We need to
know your parameters here, can do no more for you without this
My Duncan head coral has shrunk as well but it keeps falling off, as
every time I place it somewhere the snails or the large urchin pushes
him over so I'm thinking he's hurt from all the falling.

Thanks for responding, the sump is 32 x 18 and the protein skimmer is a
ASM G2, the main pump is a Rio 26HF the lighting is a TEK light with 6
bulbs, I was running the lights for 13.5 hours but when the red slime
showed up I was told to lower it to 12 hours.
<Your problems with your Xenia started pretty much when you dosed to
remove this slime, so this is the source of your issues. This algae

Here is the rest of the info, you mention charcoal, do you mean normal

Dying Xenia/Xeniid Health/Systems 2/12/10
Hello Dear Knowledgeable Crew.
I have spent the last few days reading everything I can find
about the pitfalls of raising xenia, but alas it was too late to
save my specimen.
I was wondering if you could perhaps shed some light on to the
specific cause of my xenia's decline.
I bought this frag (xenia elongata I think) from a guy who breeds
The thing looked incredibly happy in his tank (pulsing like mad,
standing straight up etc).
My xenia seemed okay when I added him/her/it to our tank. But he
never opened fully. I moved him around to try and get to a place
where he had high, indirect flow, and near the top of the tank to
be near light.
Yesterday, I noticed small lesions (or bubble like things) at the
base of the main trunk.
Later, the neck near one of the bushels of 'hands'
started to pinch and turn dark purple (he was light purple
He was near a maze brain at this point, then I read the brain
might sting him. And moved him away.
The constricted purple spread to his whole body and he shrank
down to a limp white/purple version of his former glory.
Now he's pretty much dead I think.
<Allelopathy seems to be the culprit here. Your Maze Brain
Coral (Platygyra sp.) will shoot out sweeper tentacles in the
evening and very likely stung your Xenia.>
I have 20G w/ 10g sump. About 25lb live rock.
2 power head at opposite ends + plus return pipe for flow.
-->Several coco worms
-->Maze brain (not sure of the exact species)
-->Green star polyp
-->A few mushrooms
<The Green Star Polyps and Mushrooms are moderately aggressive
in terms of allelopathy especially in smaller systems such as
yours. This could also have had a role in your Xenia's
demise. Good chemical filtration such as
Chemipure should be used to minimize the noxious compounds
emitted by these animals.
The use of a protein skimmer is highly recommended and will also
help much in this regard.>
I use Canadian tap water dosed with Nutrafin AquaPlus.
Lights are 1 15w 10000k t8 and 1 15w actinic t8
Nitrates about 5-10
temp is about 78degrees
I have not been dosing iodine, or calcium.
<Dosing both calcium and magnesium is necessary for your brain
coral and other hard corals. Iodine dosing is also beneficial for
Xeniids and do exercise caution dosing as overdosing can be
I can understand if something was off in the tank and he died
slowly over a few weeks. But he lasted about 6 days. So I
obviously did (or the tank did) something traumatic. Any idea at
all? I moved him (carefully!) too much?
I would love to try again, but I need sort out what I did wrong
<It is uncommon for Xeniids to perish for no reason. Although
Xeniids can behave unpredictably, it is their sensitivity to
changes in basic water parameters that can be detrimental to
their health in most cases.
Because of this, many experienced reefers will use Xeniids as a
visual barometer for system stability. Do read here and related
articles/FAQ's re Xeniids.
<You're welcome. James (Salty Dog)>
Please help me continue to love xenia!
<Knowing any marine animals needs/requirements is the first
step to success.
Keep reading/learning, much to be found on our site.>
mystery item in my reef! -- 02/08/10
Hello... might I start by saying I love your website?...Ok, I
LOVE YOUR WEB...oh ok I'll stop sucking up now. Anyhow, to
get right to the point.
I have this lovely little thingy (actually there are two of them)
growing next to my group of pulsing Xenia at the bottom of my
tank. I think it kind of looks like a bubble anemone. But I'm
not sure what it is.. it doesn't really look like an Aiptasia
to me either though. There is the large one in the pictures you
can see visibly, and another about a third of the size next to it
behind one of the Xenia stalks. I would say the size is about as
big as the diameter of a small marble. It is greenish in color
and has bubble tips at the end of it's tentacles. It's
structure seems to be jelly
like and will contract when irritated. It also seems to have a
mouth at the center and today I tried target feeding it and it
seems to have liked it, as it closed in around the food. Of
course it could have just been reacting to a foreign object, but
it seemed to hold onto the food and act like and anemone working
its tentacles holding the food in place (at least it seemed so),
it was hard to tell it is so small. I am attaching a couple pics
for you to look at. Hope you can help me identify this thing
whether it is something I should keep.. or worry about... thanks
<I do think this/these may be Stichodactyla tapetum, but might
be Anemonia. Please see here re:

I hope you can help. Two weeks ago I purchased a Xenia rock with
approximately ten or so stalks, the next day they started to die off. I

<Can be; esp. when moved... to "differing
and to try an Iodine cleanse which I did. I examined the rock and found
what I thought was an Anemone but not sure what kind and it was eating
the Xenia . Through internet research I found it to be a shag rug
<Aeolidia papillosa? I doubt this is the species here... This is a
cold-water animal. Could well be something very similar however that is
how can I destroy it I before it goes on to something else?
<Yes... I would siphon it/them out, or use a pair of long tongs to
I do like the Xenia and it has destroyed about 90% of the rock.

White spots on xenia -- 01/30/10
Hi, Thank you for your dedication to this web site. I am a
regular visitor and have learned so much. I find you all to be
I have a pulsing xenia, photo included, that has white spots
which I am having difficulty identifying through web sites or
store where purchased.

2 coral grasses, large clam, bubble tip anemone, Sailfin tang, 2
peppermint shrimp, brittle star, urchin, emerald and porcelain
crab, diamond blenny, 2 clowns, gramma.
I do a 4 gal change once a week
and a 15 gal change with gravel clean once a month. I alternate
flakes with brine and emerald delight. I add MicroVert,
PhytoPlex, and Zooplex every other day. Everything seems to be
doing good and now I notice these white
spots. Any ideas? Thank you for taking the time to help me!

Parasite Problems/Snake Oil Remedies --
<Hello Ashley! JustinN here>
I have a problem in my tank and I believe it is related to parasites,
but I'm not sure what to do!
<Lets see if we can help!>
I purchased a new Ocellaris clown a week ago from my LFS. I do not
quarantine as I don't have the space for another tank (I know you
will hate that!).
<You are correct, and I think you also now see the benefit of a
quarantine configuration. Please do consider setting one up in the
future -- remember, the tank doesn't have to run all the time, only
when you're quarantining new purchases. If you quarantined fish, I
bet we wouldn't be chatting now!
A few days later I noticed it had "clownfish disease" (or so
my LFS owner thought at least).
<I assume that Velvet or Brooklynella are the 'clownfish
disease' that is being referred to here -- is possible, not
I did a 5 minute freshwater dip and put him back in the tank. He looked
mostly better, but a few days after that my Purple Firefish died
It had one small white spot (about 1/2 cm or so in diameter) but no
other obvious signs of distress or disease. I also noticed that my
Banggai Cardinalfish had developed what appears to be fin rot. His fins
are smaller, the base of each fin is red, and some are covered in a
cloudy white film, one is even "glued" to his body by this
film. The clown still had one area of missing scales but looked better
<Sounds like a toxic water condition to me -- are you testing your
tank regularly on your own?>
My LFS owner recommended I treat with Ruby Reef's Rally, but this
is the third day of treatment and I see no improvement.
<And you will likely not see any improvement -- this
'medication' is akin to snake oil, a hoax... have a read
http://www.wetwebmedia.com/homeopathfaqs.htm and here:
http://www.wetwebmedia.com/medfaqs2.htm -- search for "Ruby Reef
Rally" within these pages for general consensus of these
The Cardinalfish is only getting worse. Just prior to this outbreak I
added a Pulsing Xenia Coral. It looked perky the first day, but it fell
into a crack and I had to gently pull it out by the stalk as I could
not get to the small rock it was on (after this I glued it to a bigger

effects to Xenia sp.>

droopy, is not pulsing, and is turning a dark brown color at the

Rally, and other similar 'cure-all' medications, and found that
within a few days, a tank treated with Rally would have its Xenia sp.

added to a reef tank.>
I have a 38 gallon tank with a bunch of live rock, a Galaxy coral,
Frogspawn coral, many purple mushrooms, a Monti plate coral, 1 Blue
Star Leopard Wrasse, 2 Ocellaris clowns, 1 Banggai Cardinalfish, 1
Mandarin Goby, 1 Skunk Cleaner shrimp, 1 Harlequin shrimp, 1 Sally
Lightfoot crab, several blue-leg hermits, and a bunch of different
snails. I use RO water from my LFS that they mix with aquarium salt and
I do water changed bi-weekly so tank parameters are always normal.
<Are you testing these parameters, verifying their normalness?
Please do provide actual figures -- much easier to provide
What can I do for the Xenia and the Cardinalfish? Should I continue
treating with Rally, try something different, or just let it be? I am
leaving town tomorrow night for the Thanksgiving holiday (but will
return Thanksgiving night). Please help!
<Stop treating with the Rally post haste, and add some activated
carbon and/or Poly-Filter to remove the excess medication from your
water -- your Xenia may not last much longer if you don't. Beyond
this, I would test your water and verify where your parameters
currently sit -- the issues sound most like toxic water conditions to
me... please do provide further substantial details so we may paint a
better picture here. Good luck!
Xenia hlth. issues -- 11/17/2009
<Hey Joshua! JustinN here tonight -- combining both your emails
together for simplicity of response!>
Hey guys! So..I have a problem (go figure) and I thought I would ask
the "Oh So Wise" Gurus lol.
<*Sagely* Ask away, my son. ;)>
I have a 90 gal salt tank with metal halide (sorry I can't think of
how many watts right now, and I'm not home). I'm running two
Remora Aqua-C protein skimmers, I have a 4 inch DSB, and two 600-gal
Hydor Koralia powerheads. I know, I need to get some more circulation,
I'm working on it and adding a sump tank.
<Is not completely stagnant, better than many other situations...
the sump will help though.>
Anyway, I have a blue Xenia which I bought about 6 months ago and it
has been doing great! Grew from one base to 3 major bases now.
<The true 'seaweed'>
Over the past week, the polyps just suddenly sagged and it has looked
pathetic ever since. I am pretty sure it is dying, since this happened
to another Xenia I had before I bought this one. It is slowly shrinking
<This does occur on occasion naturally, a wax-and-wane of the
population, if you will>
I haven't added anything, and just got done with a 20% water change
and it made no difference. I make my own salt water and test it before
use, and it looked fine. Everything else seems to be doing ok as far as
corals and fish go.
<What other corals are you housing here?>
I have been fighting a Cyano outbreak for months now, and it is not
completely gone, but has been drastically reduced to mostly on the
glass and sand top. I have tested for phosphates, nitrates and ammonia,
all at zero. (of course, the Cyano would just consume whatever is
available so I consider it a false negative).
The only think I have noticed is an outbreak of deep red algae, which I
assume is a type of Cyano, covering the rocks very rapidly, including
the rock with the Xenia.
<If it is slimy as well, is almost certain to be Cyano as well...
comes in many shades.>
So, I have been doing water changes and siphoning out as much of it as
I can, and it has helped but the Xenia has not improved. Any
Need any more info??
Thanks guys for all your help!
<Need a bit more info than this to advise.... which is conveniently
Sorry, I re-read my last email and there is more information that I
should have given. The Xenia are on a rock all by themselves and
"upstream" from any other corals (about 6 inches from the
nearest), so I don't think chemical warfare is the culprit.
<Mmm, can still be the case -- allelopathy is a chemical situation,
carried by the waters of the tank -- sweeper tentacles and the such,
direct Cnidarian stinging would be the issue in closer quarters... what
corals are housed here?>
I dose periodically with "Fuel" from AquaVitro, to keep a
decent flow of nutrients in the tank (About twice a month), my pH is
about 8.3 my salinity is in the range it should be on my specific
<Salinity numbers are important here, please do provide.>
My alkalinity is high (too much buffer, but corrected with water change
because my calcium levels dropped to about 140).
<140? Is this a mis-type? This is exceedingly low -- perhaps your
buffer addition caused a precipitous event, and your water balance is
still skewed? Have a look here --
http://www.wetwebmedia.com/alkalinity.htm and related
They are in a place of good flow that isn't just from one
direction, and the only other thing I can think of is that I dosed with
some Amquel to help neutralize some of the dissolved organics that are
causing the BGA to bloom. Amquel shouldn't affect xenia though
<Well Joshua, the Amquel shouldn't affect the Xenia, but I have
heard more than one anecdotal story of people who've had
inexplicable problems when using this product in a reef setting...
Amquel's main purpose is the neutralization of Chlor(am)ines and
Ammonia from new treatment water -- in a saltwater setting, you'll
optimally be using RO (or preferably RO/DI) makeup water before mixing
your own salt. Treating the tank itself with Amquel will do nothing to
improve your Cyano issue, and may well exacerbate it. What's needed
to defeat the Cyano, is additional water flow, and regular water
changes with very clean water. Have a read through here:
and related subheadings. Let us know if you have any further questions!
Xenia hlth. issues -- 11/17/2009
Hey Justin! Thanks for the quick response!
<Glad to help!>
I agree with your assessment of Amquel, I talked to one of my LFS guys
about it last night. I was under the impression that Amquel neutralized
nitrates, nitrates, chlorine and ammonia, which is why I put it in the
tank. Didn't realize that it does all of that simply by
neutralizing the ammonia and chlorine...sad day. Anyway, he said he has
had some customers have the same problems. In fact, it is his theory
that anything that forms a slime coat maybe hazardous to photosynthetic
inverts, as he has lost some corals because of that.
<I would agree with this assessment -- this is not the first I have
of problems with Amquel in a reef tank.>
Guess it's going in the trash because I use RODI water so there is
no need for it.
My specific gravity is 1.022, and yes my calcium levels were very
<I would get this raised to 1.026 over the course of several days --
those within your care will love you for it!>
I guess I over did it on alkalinity lol.
<I'd say so! I'd work on re-balancing this sooner than later
-- daily water changes to regain a control on ionic balance.>
I'll fix it right away by doing a few water changes and monitoring
the balance of calcium/Alk.
<I'd go so far as to abstain from any kind of dosing in this
critical time period -- get your water changes done to get your water
back in balance.>
As far as corals go, here is what I have: 1 small green Sinularia, 1
purple/blue Ricordea, 2 red mushrooms, large cluster of Zoanthids, 2
clusters of green star polyps and a small Montipora. I have everything
pretty well spaced out as far as I can in the tank.

Pulsing Xenia/Compatibility 9/23/09
I had a Camelback Shrimp and a Pulsing Xenia in my 14 gallon BioCube
fish tank. Two days ago, (for the first time) I saw the shrimp eating
A few hours later, the shrimp was on its side twitching and died this
morning. Are the two related? I was not sure in xenias can be
poisonous, or if this is a coincidence.
My water parameters are:
Salinity -- 1.025
Temp -- 78 Degrees
pH -- 8.1
Nitrite -- Undetectable
Nitrate -- 0
Calcium -- 370
<Kristi, Camelback Shrimp should not be kept in systems containing
They are known to munch on these, and therefore not safe in a reef
tank. I'd do a look/see again, the shrimp
may have molted and is hiding in the rockwork. Now, to answer your
question. Soft corals such as Xenia produce an arsenal of toxic
compounds. These toxins not only deter most predators, but also can
harm neighboring corals, thus helping Xenia colonies maintain a patch
of reef for themselves. In that regard, it is possible the shrimp may
have died from munching on the Xenia.>

Help my waving hand... goodbye livestock...
I have a 33 gal tank that has been established 2 years. It has
mushrooms, Zoanthids, crabs, a shrimp, an anemone and 2 clowns + 2 blue
There is 20 lbs of live rock, + salt + a great light and filter.
Everything looks and acts right,
although the anemone
has turned white with pink tips and one clump of waving hand has
shriveled up. Any suggestions? Should I remove the waving hand?
