What is this? Goniopora Eating
Nudibranch - Phestilla sp. 6/18/08
Hi folks,
<Hi Tineke!>
Can you tell me what this is?
<I believe so. An important clue comes from what the creature is eating
- Goniopora. It looks like it's well on the way to finishing off that
poor coral. By the way, nice photo!>
This was found at a night dive in the Red sea.
<Boy, that’s been a hot spot lately! Bob and some of the crew were there
several weeks ago.>
What puzzles me are the two *horns* (rhinophores?)
<Yep, you have a good eye. The two slightly longer and lighter
appendages on the right are indeed rhinophores.>
..Is this a anemone or maybe a Nudibranch?
<It’s an Aeolid Nudibranch in the genus Phestilla. I’m not sure what
species it is, but you can see a similar individual here:
http://www.seaslugforum.net/display.cfm?id=1813
http://rfbolland.com/okislugs/phes_sp1.html (larger photo)>
Thank you for your answer.
<It was a pleasure, Tineke.>

Nudibranch - Phestilla sp. 6/19/08
Wouw!!!
<Good morning Tineke!>
This is good news! I'm very proud of my picture! :)
<You should be! It's a very nice photo.>
Thank you for your quick answer.
<Glad to be of assistance. Luckily, the photo showing the Nudibranch
actively feeding on the Goniopora made all the difference.>
Maybe I will send Rudman a copy of this Nudibranch.
<Please do. I know he’d appreciate the photo, along with location
information, etc., to add to his already wonderful site
(http://www.seaslugforum.net/).>
In the book of Nudibranchs of the world (Debelius/Kuiter)
<Excellent book.>
..it also said that this one was seen in the Red Sea by Sudan. This one
was a little bit more to the north in Lahami. When you don't know the
name it is hard to search!
<Very true!>
Thanks to you I have the name and I can look under that name on the
internet!
<Makes all the difference, doesn’t it!>
You make me very happy!
<I’m so glad to have been able to help. By the way, thank you for
sending in your photo and inquiry!>
Keep up the good work!
<Heeee! Thankfully, this sort of “work” is fun!>

Shell or Nudi 07/07/08
Hey Sara,
<Hello Tineke>
Here the answer of Bill about the *hairy* Shell. He is also not able to
determinate this complex thing.
<Oh, how kind of him to answer you so quickly. He is a fabulous man.
Thank you so much for sharing his email with us. And I think he is
giving you an answer (but is simply being prudent in noting that he
can't be certain with only pictures-- which is often very true of these
types of animals).>
Do you know already something about that strange sight I send you of the
Goniopora columna? and
<Strange site? I'm sorry, I'm not sure what you're asking. If you're
referring the coral's general state of poor health, the culprit is
likely the Goniopora eating Nudibranch Lynn IDed for you. The coral
certainly looks as if it's being preyed upon. Or was there something
else "strange" you're asking about?>
Greetings
Tineke

Re: Shell or Nudi
Dear Tineke
I am sure there is a snail shell beneath the brown 'growth'. I first
thought your photo showed a snail with algal growth on its shell but the
other photo shows an identical arrangement. Are the photos of the same
animal? If not I cant imagine two animals with the same pattern of algal
growth. Which made me wonder if the growth is in fact a elaborate
periostracum produced by the snail. Some snails have a 'horny' layer on
the outside of their shell and in some this has long hairs. In the
family Ranellidae some species are called 'hairy tritons' because of
this growth. There are some photos on the web - search 'hairy triton' -
but in most photos of shells this layer is removed so the shell is more
'beautiful' for collectors.
I suspect it is a snail, perhaps a ranellid, but I am afraid photos
alone are not always enough to make an accurate identification. Perhaps
it is algal growth.
Sorry I cant help anymore
Cheers

Subject: Shell or Nudi
Dear Bill,
Again a puzzle. WetWebMedia couldn't find it and referred me to you, so
maybe you can solve this problem.
There exist also a picture of this one taken by somebody else on this
site <http://www.aqualifeimages.com/> http://www.aqualifeimages.com
click on latest release and then the thirds row from the bottom. This
person don't know either what kind of Nudi this is. if it is a Nudi. I
know the shell (Hydatina physis )looks very much but his mantle is not
the same as on my picture.
I hope you have the answer,
Greetings from Holland,

Re: Shell or Nudi 07/08/08
Hey Sara,
I have never seen this Goniopora like this before. It looks like it can
not insert his *tentakels* because they are too thick and too full with
water... so can that be a disease or a deformation?
<It is likely environmental. Have you had any sudden changes in salinity
or temperature?>
That is what I like to know. I haven't touch it but normally when you
touch it, it will withdraw its *tentacles* so you will see only the
*flower*tops like some parts on the picture.
<Unfortunately, the coral is definitely stressed/ill. I still suspect
the Nudibranch as the culprit. However, it could easily be something
else causing this. Goniopora sp. are notoriously difficult to keep and
require a lot of dedicated care in feeding properly. This is a good site
for more info:
http://www.goniopora.org/>

<Best,
Sara M.>
Re: Shell or Nudi 07/08/08
Nice link, Sara, of the Goniopora!
When I think back I can't think of something different in the coral and
his environment. This was in the Red sea.....so not in an aquarium.
<Ooohhh... so sorry I misunderstood!>
Is was a kind of passage where we went through, swimming over all kind
of corals. As you can see on the picture only this only colon was
stressed/ill.
<Again, it does look as if it's being preyed upon by something. The
pattern of dying tissue doesn't look like a disease, but as if something
is eating it.>
All the other colonies around are normal. I looked at the big picture but
could not find a Nudi or whatever.
<Oh, just because you couldn't find it, that doesn't mean it's not
there! They are VERY good at hiding. Or, the predator could have simply
moved on by now.>
Well it will stay a mystery I think. No problem... I have more
mystery's! :)
<cool>
Thank you for all the answers.

sps Birdsnest dying 6/18/08
My large Birdsnest sps is dying from the bottom up and is continuing daily.
I have lost 2 other sps corals
<What species?>
in the last month and think I may be doing something wrong. I have a 75 gallon
reef with 80lbs of live sand and 60lbs of live rock. The lighting is two 150
watt MH pendants with 14k bulbs.
<How new? Do you have a PAR meter? Can you borrow one?>
I have a rio 2100
<Mmm, not very reliable...>
return using a 20 long as a sump to house heaters and skimmer. In the tank is a
Koralia 4 circulation pump and I have a 29 gallon refugium that is next to my 75
pumping about 200gph constantly.
<Good>
My water parameters are fine except my calcium does fluctuate from 380-500.
<Yikes! Why such a large range? How much Magnesium do you have?>
I use SeaChem additives consisting of 8.4 buffer, ions, fuel,
<?>
and calcium. The Koralia 4 is pointed at the Birdsnest so I don't think it is
due to current.
There are mushrooms with in 2 inches
<Oh!>
of the Birdsnest, but will the sting of a mushroom kill the whole sps colony if
it is only close to one of the branches?
<Not necessarily>
Please help me save this beautiful piece and give me any ideas as to what I can
do whether is be fragging the dead or moving it altogether.
Thanks
Clint Shea
<Please read on WWM re Cnidarian Compatibility, and get back with me re the
questions above. Bob Fenner>
Goniopora - single polyp damaged –
6/17/08
Hi,
<Hello>
I had a look at my Goni today. Unfortunately I noticed that since I
cleaned my tank yesterday one of the polyps has died, or something,
and there seems to be a dark red crusty bit around it.
<I see this>
I am hoping hoping hoping that this is just a single physical injury
rather than the start or something sinister. When I cleaned my tank
yesterday, I moved it so i could clean underneath it , but i noticed it
was within tentacle reach of my Euphyllia
<... trouble>
and promptly moved it away as fast as i could. Could a sting from the
Euphyllia have caused this?
<Oh yes>
Attached is a photo of the otherwise healthy Goni (the tentacles are
closed because I squirted water at it to make it close for the photo)..
Thanks in advance
Lai
<This genus of Poritids is notorious for dying easily in captivity...
and STILL being too popular in our interest (easy to collect, common...
and people continue to buy). And each polyp needs to be fed... All this
you likely are aware of; I state it for the uninitiated browsing in
future. If it were me, mine, I'd leave this colony put... In time, with
care, it will regenerate, even make a new polyp in the corallite/space
available. Do see WWM re Euphylliid et al. compatibility. Bob Fenner>

Pink Birdsnest algae growth
5/28/2008
I seem to be having a weird
problem with my pink Birdsnest (Seriatopora hystrix). I'd first like to tell you
that this is the ONLY sps that I am having a problem with. The Birdsnest keeps
growing a brown algae on the branches.
<Indicative of...>
I usually manually remove it everyday, but this algae keeps coming back.
<Something amiss....>
Originally I thought it was a flow issue, so I moved the Birdsnest into more flow
and the same problem keeps happening. The coral is still a rich pink and extends
its polyps. I'd say it was a nutrient problem, but none of my other sps corals
seem to be growing this algae and all are growing well. So any ideas on the
issue of the algae growing Birdsnest would be most helpful. Another quick
question, I have a cream Pagoda Cup that has not been polyping lately...the
Birdsnest has always had the algae problem... the pagoda shows no signs of
deterioration, and starts polyping but does not come out fully like it used to.
Thanks for all the great advice.
<with either the mix of species, their physical placement here. I would try a
general "curative" containing iodine/ate... and read here:
http://wetwebmedia.com/cnidcompppt.htm
Bob Fenner>
Re: Pink Birdsnest algae growth
I'm not exactly sure what a
"curative" is,
<A treatment of some kind... a "medicine" if you will>
could you explain this to me? Is it an addition of iodine/ate, or is it a dip? I
currently use Lugol's solution for my iodine supplement.
<A larger dose of this may be of use... Along with an free iodine test kit. As
stated though... with the reported good health of other SPS, this is likely a
case of allelopathy. RMF>
Flower Pot Problem, nutrition
4/27/08
Hi, Love your site, have found answers to numerous questions and
info is very, very helpful. Can't find an answer to this one, so please
help. My Goniopora (yes I know, bad choice, learned this one too late)
seems to be hemorrhaging.
<Mmm, more starving>
I have attached a pic of last week and now (since last night, when I
noticed the problem). The only thing I can think that could have
happened would be a bout with a snail or a hermit, nothing else really
comes close to it. My question - is there any chance to save this guy or
can this situation be polluting the tank and possibly harming other
inhabitants (clownfish, mandarin dragonet, tiny hippo tang, six-line
wrasse, feather duster, elegance coral, candy cane coral, one Ricordea
mushroom, larger unidentified mushroom, and button polyps, along with
the requisite snails and hermits) and should I take him out immediately?
Or something in between?
<Mmm, if you had/have a much more established, even "gunky" system, area
like an "old refugium", this would be a good idea/move... But really
what this colony needs is attention to making sure each polyp is fed...
Read here: http://wetwebmedia.com/poritidfdgfaqs.htm
and the linked files above>
FYI, water parameters always in line, ~25% water changes every weekend.
I hate to lose it and would make serious attempts at rehab if it were
possible, but I'd really hate to lose anything else because of this
situation. I await your stellar (as always) advice. Best regards,
Heather

Flower Pot swollen
2/27/08
I have a green flower pot in my tank and it's been doing very well, I was
originally told they were pretty easy to keep,
<Yikes, no. If we're talking about Goniopora sp., they are not easy to keep.
Please see lots of info available here:
http://www.goniopora.org/>
but today it's gotten swollen, the tentacles aren't reaching out, but it's just
all puffy. The ammonia, nitrates and nitrites all test at zero, but I also just
lost my Scopas tang, who was gilling at the bottom. The only other fish in my
tank is a Mandarin fish, which I acquired today, and I have no idea what went
wrong. The tank is an 8gallon nano,
<Wow, those are probably two of the worst possible livestock choices for a nano
tank. Please research your live stock purchases before you make them. Mandarin
fish need at least 50lbs of well established live rock (and probably also a
refugium) to get the live food they need to survive.>
with a couple other little corals in it, the Scopas was just in there till our
50 gallon matures. He was only about 2 inches long.
<Even 50g is probably too small a tank for a Scopas tang. Please see here:

Goniopora....Good. and kicking.. Non-native speaker
2/26/07
Hi guys.. this is RX. I had been reading articles abt Gonioporas and how
hard they can survive in captivity..
<Yes, generally lost w/in a month>
but i really dun understand.. because i have been keeping it for a long time...
and nothing has gone wrong so far...i nv moved it anywhere to prevent shock.
it just keeps growing longer and fatter...it's so lovely...
<Are fine if kept in "not-too-clean" circumstances, and left alone, fed...>
i dun know why i manage to keep it. but i heard ppl saying that Iron and Mn are
important for it...
<Can be...>
how true is this statement ? i know it's unfound because no one really
experiment with keeping them without iron and Mn.
<These are essential "micro-" nutrients... Are trouble if completely missing...
or other chemical, physical conditions preclude their being absorbable>
and it happens that my LFS sells Fe indicator and Iron-only supplement... should
i buy it ? what level should Fe be at for salt water reef tank ??
<Mmm, please see WWM, the Net re... there is no simple, short answer... but
generally not necessary to add these elements if using a decent salt mix, not
having "out of balance" situations with other aspects of water quality...>
btw, my water quality is at it's best. no ammonia and nitrite.
getting another skimmer soon. I am doing extreme skimming.. i dun bother with
nutrients because i have a DSB. i think it can supply the tank with nutrients..
and i uses all SeaChem products...
<Good>
in Singapore, we can get corals at low prices unlike u guys in America because
we get supplies from Indonesia and Philips.
<I have been to your country many times and agree>
Phillips. supply are more expensive...we can get a hammer coral for US$10.
but that's the price i get from the local fish farm...i dun get supply from LFS
but from the farm... is the price relatively cheap compare from USA ??
<Oh yes>
but on the other hand...we can't get things from Hawaii like u all... haha...it
cost a bomb but corals are Indonesia and Phillips are pretty enough... :)
<Yes... but unfortunately due to the same price/competition concerns, Singapore
doesn't offer hardly any tank-bred animals... I have never seen tank-raised
Clownfishes in your country...>
make a trip to Singapore somedays...and u will find that some corals are in such
a good condition that u can't believe it...i can bring u to the farm...:)
<I thank you for this offer>
a lot of articles highlight problem regarding shipping and blah blah blah....
but it doesn't happened here...except for diseases problems...
because the locals dun know and dun practice coral dips...that's the problem...
<Ah, yes... perhaps you can/will help them? Are you a member of the Sing. Reef
Club? Bob Fenner>
Why is this happening? Can it be saved?
Goniopora hlth., no useful info. 12/26/06
My beautiful flowerpot coral was doing so well. A few nights ago, there
was a microbe/plankton bloom
<Caused by?>
which clouded up
the tank. As expected, it went away but now my coral is separating from
it's base. It's also not extending much as it did before.
Is there anything I can do to fix it?
Thank you,
Lisa

Re: Why is this happening? Can it be saved? Still not reading re
Goniopora... 12/27/06
Hello Wise Ones :)
<Mmmm, Soitainly!>
Thanks for the response. As to what caused the bloom? I have no
idea. I read from your site here
http://www.wetwebmedia.com/reefmntf.htm that this could be caused by
many thing including some reproductive event. It lasted just one one.
<Units...>
I increased the amount of bubbles into the tank through the power head
in hopes of getting some of the particles out sooner and added carbon on
top of poly pad in the sump (first stage where water enters above bio
media) and the cloudiness disappeared by the next day.
<I see>
Everything else seem to be fine. I didn't worry too much about the
sudden cloudiness after reading your page. Nothing had changed
chemically, no new animals other than 3 tiny lettuce slugs had been
introduced and there hadn't been anything else done differently.
<Okay>
I will try moving the affected coral to the refugium. I did add live
sand to the refugium about a week
ago, before it had a bare bottom, but after reading about the benefits
of live sand in the refugium, went
ahead and added some. I probably need to trim back the macro algae.
Another coral is bleaching out. I moved it from it's position under the
light where it had been doing great up until a few weeks ago but it
continues to degrade. Should I move that to he refugium as well or is
all hope lost here?
Thanks,
Lisa
<... you should read... again:
http://www.wetwebmedia.com/gonioporapix.htm

Re: Why is this happening? Can <Goniopora> it be saved? Reading... try it
out... 12/28/06
Thank you Bob. I did read. The bloom lasted one night (sorry for the
omission).
<No worries... is what I assumed>
The Goniopora seemed to be thriving until the bloom.
But I understand how hard it is to keep. It just seemed to be doing so well
prior.
<"Things... are not always to often what they appear">

Another Goniopora down 11/10/06
Hello all
<Dray>
I've had a bit of a problem with my Goniopora
<Not easily kept...>
and I was wondering whether ive done the right thing. It's a long story so ill
start from the beginning.
My kit: Trigon 190L corner tank
20w t6 blue and white tubes (soon upgrading to an ibar)
Fluval 203 floor standing filter
Juwel filter that came with the tank (400L) I think both filters are
filled with pebble sub striate with 2inch sponge caps (to catch the gunk) that I
change weekly
<Good, necessary>
Tunze 500L skimmer that ive got running at about 65% efficiency
90L/hour power head
300L/hour power head (plus what ever the filters put out
400? 203?)
And about 25 kg.s of live rock
Fish: 1x percula clown (had two but one had a fight with a pump and
lost)
1x valentine puffer
2x scooter blennies
1x chalk (sleeper) goby
1x royal Gramma
Inverts 1x cleaner shrimp
5x red leg hermits
8x turbo (pff slow ass) snails
4 or 5 half shell snails
1x crab (which I found today) looks like a clump of yellowy
brown stuff but ran into a crack when I tried to remove it.
COOOOOOLLLL!!!!!!!!!!!
1X toadstool
1x anemone
<Not appropriately kept with...>
1x small frag of star polyps (green and growing) fast COOL!!!
1x red fingered gorgonian???
<Yikes...>
1x small frag of yellow stuff kind can't find the name
<...>
Ok that is that over with now with the story
I was having a problem with my toadstool and for the life of me couldn't find
the reason for its ailments. I checked your site, asked the guys down the LFS
and other fs's until I met this Guy who was obviously god ,who asked me about
300 questions until he said do you have any fish that sit on more than one type
of soft coral?
<Good question>
Hhmmmm yep! My saffron goby. His (coz that's what I call him) two favourite
places are either on my Goniopora or on the toad stool.
"god" said that he could be carrying stinging cells from the Goni to the shroom.
So I got rid of him (back to the LFS) and the shroom is now back to its full
bodied self.
<Bingo>
However, today I noticed that the Goni seemed to be receding on its rock and
getting smaller, so, I thought ide move it. On touching "the rock" it was
actually white rotting stuff black underneath.
<Yeeikes>
So ive chucked it in the Erald Flynn "bin"
What was it,
<Necrosis... the Flowerpot was dead, dying...>
and did I do the right thing, and is there any thing else I should do to the
water, incase of toxic build up or suchlike.
I eagerly await your reply
Ps would be able to reply to XXXX
Many thanks WWM

Re: Another Goniopora down - 11/10/06
Hi there bob
Before I start I would like to say thanks for the reply (thanks)
But some of your comments have got me worried. Specifically about the
gorgonian (Diodogorgia spp) I've read that they may/do produce toxins but
rarely pose a problem as this is a predatory defense.
<Yes>
was it the gorgo you
were expressing concern about or the toadstool (please please please don't
say both )
<... the two of them>
and would it just be proximity or just that its in a 190L tank?
Your advice is greatly appreciated

Porites lobata health - 03/12/2006
Sorry for the e-mail but my google searches, postings in a couple of reefer
chat rooms and research in my textbooks have not helped me.
I have red and green coralline algae encrusting on my Porites lobata. I fear
the Porites is dying (dead already!). The commensal worms still seem in
relatively good shape, although I do know they could stay "alive" for awhile,
even though they are dying also.
Any suggestions regarding placement, feeding or other that I could use to try to
save the Porites?
Water parameters are all good, consistent and my other corals and fish are doing
(and have been) doing fine so no changes there.
Thanks in advance for any help. <Joe, unfortunately these are some of the
hardest corals to keep for any length of time. These corals require intense
illumination and pristine water quality, and even at that, rarely survive more
than a year. James (Salty Dog)>

What's wrong w/ my Alveopora 12-06-05
Hello, the super hero team of WWM,
<Hello>
I bought this Alveopora about 2 months ago. It is growing nicely and everything seems fine and dandy.
All water conditions are excellent (like you have never heard that line before),
pH 8.3, ALK 4.5, Cal 425, no nitrate, nitrite, ammonia, phosphate, and silicate. And I have about 32x water turn over rate
per hour for the tank.
<Sounds good so far.>
Well, while I was inspecting all of my corals' growth, I've found something strange about my
Alveopora. As you can see from the images, there seems to be some sort of fuzziness/hairy stuff growing underneath the
coral. It seems to grow behind its base and that's where not much flow are going through there (of
course).
http://img332.imageshack.us/my.php?image=dsc015976dk.jpg
http://img332.imageshack.us/my.php?image=dsc015951eb.jpg
It is doing fine and no sign of recess.
<That is what truly matters.>
What's the problem? Should I take it out of my tank and brush those fuzziness away? Or that's some sort of calcium
build up? Any suggestions? Thanks!
<Not calcium or anything to really worry about at this time. If it starts to affect the coral, then a dip may be
necessary. Alveopora are so touchy that I really would not mess with it until
necessary. Hope that helps, Travis> |
Dying Flowerpot (4/26/05)
Hey Guys, just a quick question about Flower Pot Corals. <aka Goniopora> I
have one that is slowly dying and I showing about 1/3 of it's skeleton. <This
is the fate of 95+% of Flowerpots. They are quite unsuitable for the vast
majority of marine aquariums.> Any way of bringing it back to life? <Highly
doubtful at this point.> I had some water quality issues, but now everything is
back to normal. <While this may have hastened its fate, this likely would have
happened eventually anyway.> If you know of any remedies, it would be greatly
appreciated. <Do you have a refugium? It might help to put it in there. <Search
Goniopora and flowerpot on WWM for ideas and discouragement from buying
another.> P.S. Thanks Bob for the info on California Rays. I dropped the
temperature in my tank and now he's acting normal. <Glad to hear, Bob is always
a great help. It's an honor to help him in this endeavor.> Dan, Salt Lake City
<Steve Allen, Taylorsville.>
Coco Worm & Goniopora
Hello,
<James here>
I have a 30 gallon reef tank, four fish, and an assortment of hardy corals (clove polyps, mushrooms, open/closed brains, yellow
Fiji leather) and recently acquired a Goniopora/green fluorescent buds with pink stem. I know,
all but impossible to sustain these corals, however it was a gift, and cannot be returned. It's been doing okay for the last 3-4 wks., and
recently my maroon clown began embedding itself in it constantly which is awesome to watch. However, the
Gonio does not fully expand when I observe
it, and the clown fish still tries to rub up against it often. Has the maroon disturbed this coral or does
Gonio sometimes shrink up? Until now,
their relationship seemed quite natural and healthy.
<I'm thinking you may not have enough light for this coral, but if the clown is always in there, I don't believe the coral will fully bloom. It's a difficult question to answer 100% correctly being that the
Gonio is going to need pristine water quality/lighting to show it's true form to start with. You may want to do a
Google search on the Wet Web, keyword, Goniopora or flower pot corals, and read about them.>
I also acquired a coco worm which I read has the reputation of being fairly easy to keep. Plus I have a feather duster which has always done well
(although I know these are 2 different invertebrates). However, the coco worm usually does not bloom and stays in its tube. It has just approached
the surface of the rim a handful of times and doesn't even come out when I feed the tank
Cyclop-Eeze or DT's phytoplankton. I know it's a timid creature that is easily frightened by passerby fish as I've been witnessing,
but with a 30 gall tank and 4 fish, there is really not a spot I can put this coco worm without fish swimming by. Any suggestions or should I just
give it more time? I've had the coco worm for about 4 days now.
<The coco worm is probably coming out in the evening when the activity is minimal. You might want to feed at that time and observe. James (Salty Dog)>
Another dying Goniopora 3/23/04
Hello Everybody
<cheers>
My Goniopora coral started getting this translucent brown film over it and it
has been covering the piece more and more each day. I sent a poor picture of it
and I hope you can make out what's going on. Is this coral dying and if so what
could of caused this to kill this piece?
<this is how most Goniopora end up within weeks/months of import... they die
in most tanks and really should not be collected/purchased (by you/us being
educated consumers and denying them at retailers)>
thank you Kirt Joseph
<please do a keyword search with the google search tool on our website/home
page at wetwebmedia.com
you will find numerous FAQs and other information on this sad topic for
perspective. Please do buy/use a proper QT tank to isolate this sick coral...
and be sure to employ quarantine for all new fish, coral, rocks, etc in the
future. It is critical for your success and their lives. I cannot emphasize this
point strongly enough. Read more on QT in the archives... some excellent and
recent articles by Scott Fellman, et al. Anthony>
Sick Goniopora
Hello guys and girls
I emailed a very poor picture of some sick Goniopora. It had a brown
translucent covering all over it. It started out on one corner
of the piece and quickly spread over the entire piece. I took the piece
out of the tank to wash away the brown covering and it disintegrated in
the tank. I did manage to wash some of it away in a bowl filled with the
tanks water and put it back in the tank. much of the piece looks dead and
had a little foul odor after I cleaned it smelled ok and it looks like
there are some tubes trying to blossom. Will this piece come back? I
included the best picture I have of it. I have included a picture of the
piece after I cleaned it and it is Jpeg 014 it shows it on top to the left
of the bubble. Will this fragmented crap floating around in my tank effect
the other corals, worms, polyps? I also included JPEG 008 that
shows what looks like hair algae (red) growing on a rock can you identify
and tell me if this is bad stuff and how to get rid of it if it is bad?
Thanks

Sick Coral - Help
I have a large green Goniopora? (flower pot coral) that is covered in brown
goo in several spots....disease?
<yikes... a highly infectious condition>
I was told to dip the coral in a partial hydrogen peroxide dip and watch the goo
bubble away and hope for the best.
Is this wise or just toss the coral?
<perhaps helpful, as are iodine dips and freshwater baths. Still... the coral
is not likely to survive this aggressive infection. And you really do need to
understand, appreciate and use a quarantine tank to put all new corals, fishes
and other critters in first before adding them to the display... and to use at
times such as this. The infection you are observing can easily spread to healthy
coral in the tank and take a heavy toll. I'd hate to see you learn about the
importance of QT tanks this way. Please do read up more on this ASAP.

Goniopora Ailment 4/12/04
Hello folks and thank you for taking the time to perhaps help me. I have a Goniopora
stokesii, that has been in my tank for about six months and seemed to be doing well.
<they are free-living species and need to be on the sand bottom. If they are placed unnaturally on rock (like folks
regrettably sometimes do with Trachyphyllia open brains) they seem to suffer in time (lack of
micronutrients from substrate, abrasion from polyp cycles on rock, etc?). Most will go about 6 months on rocks ;)>
The problem is that when the lights are out and the polyps are retracted I have noticed that there is an area of missing polyps. I first noticed this about three weeks ago but as the area was very small and the coral expands beautifully I felt the coral was in no real danger. Over the last three weeks, however, the area of lost polyps is becoming larger. The rest of the animal opens very well, so well in fact that you can only see the damaged area after the polyps are retracted. There is never any 'jelly' infection and no slough tissue. Might there be something that would eat the polyps and section at a time?
<yes, but just as likely could be an injury from a fish or invertebrate that nipped it... expanding now>
The coral is in a 125 gallon SPS aquarium that is lit by 250 watt metal halides. It receives moderate to strong flow and as I said the rest of the coral opens completely and covers the damage. My water conditions are as follows: NH3, NO2, and PO4 are all zero as per Salifert tests.
<do allow some nitrates for good coral health/color. About 5 ppm is fine>
Calcium is around 450 ppm, pH ranges from 8.1-8.2, and alkalinity is 2.5 meq/l.
<your Alkalinity is flat because the Ca is so high (not needed). Do consider allowing the Ca/Alk dynamic to be more even keeled. 8-12 dKH for ALK and no more than 420ppm Ca (350-420). Neither should be at the high end of either range at the same time (no worries)>
There are sally Lightfoots, red leg hermits, two camel shrimp and an arrow crab.
<none of the above are truly reef safe. All are cited as nipping coral... the sally lightfoot in particular. Read about it in the archives FAQS>
The only fish are two lawnmower blennies and a Scopas tang.
<no trouble here likely>
Any insight you might be able to offer or any suggestions would be greatly appreciated. Thank you again. Matt Hall
<best regards, Anthony>
The worm that 8 Goniopora 4/4/04
Crew of Wonders,
<wondering in Pittsburgh, Anthony Calfo in your service>
In my 175 reef I have a Goniopora, healthy and BIG for about
5 1/2 months now. I acquired it before I was to bask in the
collective knowledge of WWM. I now know better.
<good to hear, as they say "Every day, a better way">
But over the last 2 days it has been closed with little extension; I
figured it was the beginning of the inevitable. As I was
preparing the pyre, I noticed what looked like an arm of a
serpent star entwined throughout the stubs and "flowers" of
the Goniopora. I noticed that MY serpent star was across the
tank so I tried to grab it with a pair of tongs. It looked
about 4 inches long as it meandered around the coral. As I
touched it recoiled swiftly. After 3 tries I got the
bugger and placed it in a container. It has contracted to
about 1 1/2 inches and swimming with a "sine" movement. It
also "slimed" the water when I messed with it, a whitish
discharge that floated on the water. Attached is a small pic
of the suspect, to the left you can see the goo it oozed. Any insight would be appreciated, especially if it was the
culprit of the Goniopora's ills. I searched the FAQs and no
mention of the goo... Walter
<I cannot make a specific ID for this worm or even confirm that it is
predatory or simply scavenging an already (albeit suddenly, dieing or
necrotic Goniopora. I can say that is it is the former, it did not likely
arrive on import with the coral, but rather appeared recently from the
introduction of a coral, love rock, snails, sand, etc without a proper
quarantine period. Hard to explain a decided predator any other way with
5+ months of good behavior. Kindly, Anthony> |

Purple band disease Porites 10/2/04
Dear WetWebMedia Crew: Is there anything that can be done for a Porites with
purple band disease? The reading I've done only says stress or injury can cause
it and that it is common in Porites.......no mention of what to do for the coral
once it gets the disease or whether or not it can spread to other corals. Both
I and the local fish store owner here are anxious to learn more about this
disease........any help you can give is much appreciated. Janey
<I am not aware of any definitive treatment... but folks have tried with
variable success a number of standard treatments. I feel that some can help.
Starting with isolation in a bare bottomed QT tank... the application of ozone
via a controller (target a conservative 350-400 mV). Topical swabs of the
afflicted area/band may be effective too (iodine based meds). Short baths in
antibiotics are du jour in kind: Nitrofurazone is a common drug of choice. Its
all rather experimental. Please do share your results/experiences. Kindly,
Anthony>
Brown Jelly infection on Gonio
I think that my Goni might have brown jelly disease, there is a kind of orange
film developing on some of the polyps, how do I get rid of this infectious
disease and save my Gonio?
<this secondary barrage of infectious pathogens known as "Brown
Jelly" is highly infectious and so virulent that odds are not good at all
of saving the specimen. You will be lucky if it doesn't kill other corals in the
tank too (healthy established ones too!). This is just one of the many reasons
why it is so critical to quarantine all livestock for a full 4 weeks before
adding them to a display. Besides having a better chance to save the new guy,
there is always the risk of infecting some/all of the established animals. My advice
is to capture this coral underwater with a large plastic bowl and lid (the coral
is to be moved slowly and sealed in the bowl underwater) to reduce the chance of
drifting infected tissue through the water. If any pieces do float away...
siphon them out promptly... it is highly infectious to other corals. Treatments
to date are highly experimental with antibiotics, FW dips and iodine spikes. I
honestly don't think the coral will be alive 48 hours from now, I hate to say,
but do consult Eric Borneman's Aquarium Corals book for an extensive range of
options. My advice is a 60 second shower under cold tap water (seriously) before
placing it in QT. Maintain vigorous circulation and aeration in QT as well. Best
regards, Anthony>
Goniopora and brown jelly (protozoan) infection?
Hey Anthony, The good thing is that I don't have any other corals in my tank,
<a good thing>
I was coaxed into buying this Goni as my first coral by my local LFS.
<wow... if they are receptive, willing to learn... please suggest that they
browse and use our free resource/database for themselves and their customers.
Promoting success in the hobby is out mutual goal. Also suggest that they buy
either of Eric Borneman's coral books for a quick reference to not make such a
terrible mistake again>
My coral doesn't have much brown jelly on it and I am thinking that it might
just be decay of the slowly dying coral.
<agreed... simply decay. "Brown Jelly" is wickedly virulent... you
can literally watch flesh fall away over a period of hours.>
Thanks for all the help involving my Goni.
<best regards, Anthony>
Goniopora health, feeding
Merry Christmas Eve Crew,
<and to you as well my friend>
I have a few questions that I am having problems with.
1)I feed my Goniopora phytoplankton but I was wondering what else I should feed
it to ensure its survival for more than a year,
<placement on a deep sand bed or in a refugium with a deep sand be has proven
to be invaluable! Also, some seagrasses in the system for natural phyto and
epiphytic matter seems to be helpful>
2)My three spot damsel is trying to make the Goniopora its home but I don't want it
to because when it rubs against the coral, it retracts, is there anything I
can do to discourage this behavior?
<no clowns or damsels in the display at all with the Gonio... it will kill
the coral within months likely>
3)I brought it in pretty bad condition (i.e. exposed skeleton), what can I do to
try and help the coral or is it too late?
<definitely not too late... but will be slow to heal. No worries... good
water quality is enough. The fishless refugium and deep sand bed are also
crucial>
4)Does it need to be near macroalgae, if so, where can I find some?
Thank You, Lucky Ly
<not any/all macroalgae... some like Caulerpa and perhaps Sargassum may be
noxious or harmful. Look for Gracilaria, Chaetomorpha and calcareous species
like Halimeda & Udotea... better yet seagrasses if you have a deep sand bed
(Thalassia or Syringodium). Numerous places on the web sell these plants. What
big city are you near? Perhaps there is a local club you can trade samples from (look
at our links and the lists on message boards like reefcentral.com for aquarium
society listings). If nothing else... look up www.ipsf.com for Gracilaria algae.
Best regards, Anthony>
Goniopora type/health
I was wondering what kind of Goniopora this is and if it is healthy?
Thank You
<Ahh... yes. After examining it closely, I can tell that it is the half
dead type, as evidenced by the tissue recession and exposed skeleton.

Sunflower Pot
Hi Everyone,
Nice to be back again, and have quick question. I think there's something wrong
with my sunflower pot, it hasn't come out fully extended this past week.
<If this is a Goniopora sp., it was pretty much doomed from the get-go. Most
of the species collected rarely survive past 8-10 months.>
This morning, there's this film covering it (like it is inside this bubble).
What is this slimy film covering my flower pot? Will this kill it?
<Sounds like it's already dead. Pick it up out of the water (carefully, the
tissue may start pouring off) and give it a sniff. If it stinks, toss it. If by
now it's really gross looking, you should siphon off all the spooge before
handling it. It would also be good measure to do a water change.>
Shall I remove it? Help! Water parameters: Am=0, rite=0, rate=20 and pH=8.2.
<Water's fine, although you should work on the nitrate. No where near toxic
at this level>
Regards and Thank you,
<Good luck! -Kevin>

Goniopora newbie 5/3/03
HELLO ALL,
WAS HOPING YOU COULD GIVE ME SOME ADVICE ON CARING FOR A GONIOPORA CORAL. I
HAVE ONLY HAD IT A SHORT WHILE, ABOUT A MONTH, BUT SEEMS TO BE
FAILING.. WOULD REALLY LOVE TO HELP IT IF POSSIBLE IN ANY WAY. WATER CHEMISTRY
SEEMS GOOD, ALSO SINCE REEF SYSTEM IS NEW TO ME, WAS WONDERING ABOUT ADVICE ON
RECOMMENDED SUPPLEMENTS OR THINGS THAT SHOULD BE ADDED TO REEF SYSTEM REGALLY.
MAY SEEM LIKE A DUMB QUESTION, BUT, I HAVE LEARNED EACH TIME I GO TO A SEMINAR
OR READ A BOOK I HEAR SOMETHING DIFFERENT AND AM NOT AT
ALL SURE NOW
<cheers, my friend. Thanks for writing in. Alas... the problems with you or
anybody keeping Goniopora cannot be summarized in the short breadth of an
e-mail... at least not for attempts at keeping them successfully. The truth of
the matter is that they are very difficult to keep alive, and very few people
should buy them if the intent is to be a conscientious aquarist. It really is
shameful that merchants sell these/any corals/animals to aquarists without any
information or guidance. Yet some would say (I would!) that the responsibility
really is upon you/the consumer to gather information and be educated about an
animals needs before bringing it home. It boggles my mind that anyone could
bring an animal into their care without knowing its needs or if they can even
meet them! My advice to you presently for this coral is to begin with the
basics... read about Goniopora in Eric Borneman's Aquarium Corals book... or my
Book of Coral Propagation... and of course, you can/should do some keyword
searches on an engine like www.google.com with phrases including
"Goniopora" "lobata" Stokesii" "care"
"aquarium" combinations. The truth of the matter is that yours will
likely die within weeks/months like most imported. The trade/hobby does not even
know clearly what it is they eat or how we can keep them successfully long-term
yet. I wish I had better news to share with you. FWIW... success with keeping
Goniopora has been tied to maintenance in aquarium with very deep live sand beds
(6" or more) that are over one year old. Best regards, Anthony>
Porites Acclimation
Bob or Anthony,
<Greetings fellow reefer... that is to say, one who favors reefs and not
"reefer" per se...hehehe. Anthony>
I really do appreciate what you guys are doing for the hobby. I had a quick
question, I recently bought a yellow Porites, I had read that Porites did better
under brighter light, such as halide, than under dimmer lit situations.
<True for most, yes...but not all. Also dependant on condition of import.
Shallow species under duress will still need to begin acclimation on tank bottom
or like subdued lighting before full on halides. Colored Porites such as your
yellow one are indeed likely to favor extremes of light AND water movement>
I placed it under power compacts and VHO part of the tank, the
tips began to get a little brown or green growth (algae, even though I have no
algae what so ever in the tank), I moved the Porites under the halide, and it
became even more pronounced. Should I try the very bottom corner of the tank?
<yes, simply a stressed animal. And it may take some time to recover. Don't
worry about likely color changes (to brown or green)... we'll recover them
later. Let's stabilize tissue first>
My water parameters are all in line (I lost xenia, tips of hands
turned white, then the whole arm vanished (I have a Singapore angel?)),
<that will do it <smile>>
I dose the tank the GARF way, across, clams, Turbinaria, Montipora all doing
well. I have read that Porites may suffer some loss, but its not like an Acro
where you lose the whole animal.
<agreed> Thanks, Tom
<quite welcome, sir. Have faith. Anthony>
Clownfish & Goniopora Doing Poorly
Hello Robert,
<You reached Steven Pro working his shift today. Anthony Calfo and I are
filling in for Bob for the time being.>
Whenever I have a problem that I cannot figure out I know who to ask, your the
man. My female clown has been sick on/off for about a year, mostly off, but when
she does get sick it's always the same physical signs. Common features include
split tail, discolored spots around body, white mucus around gills. Not all
signs appear at the same time, but one or two together are common. I have
researched your website, and have found the best thing to do is to wait to see
how she reacts and wait, so that's what I do, but how long can she go through
bouts of sickness and remain alive in my tank. Also, she is paired with a male
and they both share a home together (long tentacle anemone) and I have never
noticed the male with any signs of disease, nor the 6 other fish in my reef
tank. What does she have? What should I do?
<This sounds more like an environmental factor or some reaction to
aggression, than an infectious disease. I would look for changes in water
quality that correspond with the symptoms showing up.>
Last question.
My two flower pot corals have both been closed, sometimes showing signs of
opening, but they never open to their full capability that they showed the first
month or two when introduced in my tank. I have moved them away from the light,
but their isn't much room in my 40 gallon. What do you suggest?
<I have no suggestion for you. Your corals will be dead shortly. Goniopora
are one of the most commonly imported corals into America and they almost always
die, 99% mortality in less than one year. They live long enough for the
hobbyists' to falsely believe they are doing OK before they taper off. I do not
mean to seem so callous, but it is a commonly known fact with this coral. One
suggestion I have for you is to go get and read Eric Borneman's "Aquarium
Corals". This should help educate you for your future purchases. -Steven
Pro>
Thanks again,
Jason
Aggression as the Cause of Mysterious Ailments
Thanks for the coral advice, I figured something was up. I think the
aggression might be the cause of the Clowns physical behavior, whenever I move
anything in the tank or the anemone moves to a new spot she gets sick.
<Also, do make your hands are clean and free from soap, hand creams,
after shave, etc.>
Thanks for figuring it out. You guys are good. I need to get some got reference
books to learn more.
Jason
Re: Goniopora
Anthony, Over the weekend, the Goni showed a moderate decline.
When I got home from work last night, my tank smelled like death. all my
snails and my starfish were dead. The Goni had died, and apparently taken a
bunch with it.
<very sorry to hear it... save a dead snail carcass for the salesclerk that
sold you the Gonio >
Of course I removed all the dead stuff immediately, prying snails from my hermit
crabs. I tested ammonia and nitrites. The nitrites were at about 2.0, and the
ammonia test kit had gone bad. I dumped the quart of skimmate that was produced
in a day, and dusted off my 2 cheapo-skimmers and set them up.
I also added about 8 oz carbon to the system.
<all excellent moves!>
Then, over the next few hours, I began noticing more death on my LR. 8"
worms that I had never seen before hanging out of their holes dead.
<Houston...we have a problem>
I didn't see any of my 'pods moving, so I stirred up the substrate, to see many,
many dead inverts floating around - some the size of small dogs. I was up till
the wee hours cleaning filters, et al. My tang showed serious signs of stress,
swimming erratically and inadvertently scratching his side pretty good during
his conniption fit.
<simply corrupt water chemistry at this point>
I didn't have salt water ready to go, so I mixed up 20 gallons and will
change that tonight. Overnight, the 3 skimmers produced about 16 oz of
thick, chunky slime.
<yummy>
This morning the fishiest seemed surprisingly normal.
<they are stoned on ammonia...heheh>
Any suggestions on what to do to help stabilize?
<simply water changes and the good skimming/carbon that you have been. It
will correct very soon and the LR will bounce back. Again...sorry to hear it>
Thanks, Daron
<kind regards, Anthony>
Re: Goniopora
Hi Anthony,
<Cheers again!>
I got another kit and tested my ammonia last night, 'only' 2.0. I changed 20g
and 2 of my 3 skimmers are slowing in production - wow, I can really tell the
difference in quality between them.
<it is amazing...folks often assume that if a skimmer isn't producing that it
means there is little to skim... sometimes it is just the skimmer. Glad to hear
you've got a good one at least>
It's sad. I spent the last month worrying about calcium and buffering
getting ready for my first coral... all of a sudden I'm back to a cycling
tank...
<disappointing bit a temporary delay. A learning experience at that>
My Caulerpa seems fine. I'm a concerned that it will die as did all
my green microalgae. I'm keeping a close eye on it.
The main reason for this email is my p. volitans. I don't know if this
injury is environmental or as a result of him wigging out and swimming into
something, I assume the latter. His nose looks like someone cut it open with a
scalpel. It's split open and swollen. Also, he only ate 1 small krill last
night, and spit it out a few minutes later.
<can and may go without food for a while...no worries. They are tough>
I fear that if it is a physical injury, that the noxious water will do much
damage to his immune system, and he won't be able to stave off infection.
<a valid concern...hence the importance of having a quarantine tank>
I WAS building a reef, but I recently acquired a FO tank... heheh.
<do consider removing the lion to a quite little hospital tank with broad
spectrum antibiotics if necessary>
Thanks so much for your help. If it wasn't for you WWM guys, I wouldn't know
what to do. This is the most depressing thing I've done to myself since I walked
down the aisle. Daron
<I most likely would have advised you to do that too... a beautiful thing.
Anthony>
Re: Goniopora II
Actually, yes - I plan to do my best with keeping this poor thing, so
anything that is within my recently-divorced budget, I will try. I could set up
a refugium - right now, I have a sump with Caulerpa and live sand. It is green
(the coral, not the sand).
<excellent... just in time for St Patrick's day. Let it have a pint of
Guinness on me>
To get a picture of what I might be getting myself into, How big, how much water
movement, and how much light would I need in this refugium? What "other
individuals" would I place there?
<in a perfect world: yank the Caulerpa, establish Thalassia sp Seagrass (no
problems with going vegetative or inhibiting coral growth like Caulerpa), put
bright daylight (and some window light if possible) colored lamps (6500-10K but
no higher) and you might even experiment judiciously with DT's phytoplankton
(more about proper dosing if you do), and keep on a very deep fine bed of sand
(needed for microfauna and Seagrass... around 5-6" sugar fine aragonite>
I do plan on eventually 'graduating' into your coral propagation book - I have
been looking in stores for a copy to thumb through, but now that I think about
it - asking you might be a little more 'to the point.' Is it a good resource for
coral beginners, also?
<if I may say so...yes. In fact, the first 200 pages of the book are
fundamental reef keeping in plain language...no Latin or coral propagating until
the last 250 pages <wink>>
Thanks. And thanks for reminding me of that autographed Terry Bradshaw poster I
had in my bedroom when I was a kid!
<yes... back when the man had pride. Now look at him...those cheesy
commercials are even too tacky for me, and I am a tacky guy! Hehe... kindly,
Anthony>
Goniopora Flower Pot Problem
I have had both a green short tentacle flower pot and a large long
tentacle flower pot coral for about 4 months now. They have been doing great up
until 2 days ago. They have recently begun to shrink and are not opening fully.
I have not noticed any recession in the tissue from the skeleton but they just
are not expanding like they used to. All of my water parameters are fine except
my nitrates which are extremely high (80+ ppm) which I am trying to bring down
slowly with water changes and the addition of Caulerpa algae. I believe the
nitrate spike occurred when I replace the filter media in my wet/dry. I am
assuming that the algae that was growing on this was also using up some of the
nitrates. The thing that concerns me is that my other corals are all fine and
thriving (Xenia, Huge Leather, many types of star polyps, button polyps,
gorgonian, small green anchor coral, cabbage coral, and some corals encrusted to
my live rock). From your site I have gathered that the flower pots need less
that normal conditions with high nutrient which I believe my tank has with the
high nitrates. I currently only dose with Kalkwasser and no other additives. I
feed about once every two weeks with a spray of plankton across the whole tank.
My lighting is 3+ watts per gallon in my 55 gallon tank. Any ideas or additives
that might help. Thanks
<Nothing much for me to say or for you to do at this point. Goniopora have a
well established history of perishing in captivity. I would suggest you stay
away from this coral for the time being until its captive husbandry requirements
are discovered. -Steven Pro>
What is up with my little flower pot?
My Goniopora has been captive in my system for 7 months and very happy might I
say opens very full everyday, And grows like a weed!
<Did you actually see an increase in calcification (skeleton) or merely
bigger polyp extension?>
My question is last 3 days he is closed shut and I see little flower heads lying
on the sand bed? Is my FP sowing his seeds or kicking the bucket?
<Sounds more like the latter.>
I have looked for the answer to no avail.
<Any of the books by Sprung, Delbeek, or Borneman discusses this coral and
its typical pattern of dying in a system after six months to a year in
captivity. Our own FAQ file on LPS has several Q&A's about Goniopora and
there historically dismal track record. All on needs to do is a Google search of
WWM at the bottom of the main page to find what you are looking for. -Steven
Pro>
Thanks again in advance almighty gurus!!!
Help! Has my Goniopora sp contaminated my tank
Hello Bob
<Anthony Calfo here sending cheers from across the pond!>
I have kept a 5ft FOWLR tank (approx 65 gals actual water content, loads of LR)
for the past 16 months . I then decided to set up another 5 ft (approx 80 gals,
less LR but still a good amount for now) tank for inverts and a few small fish,
5 in all. The params that I check are Ammonia 0, Nitrite 0, Nitrate under 20 pH
8.4 or just above.
<yes... all very well>
I intend to check calcium and phosphate when I get the kits but I do treat the
tank with calcium, iodine, strontium and invert food all according to bottle
instructions.
<hmmm... you add calcium but what about buffer? Calcifying organisms need a
supply of Calcium and Carbonate (ALK/buffer) to form aragonite/calcium carbonate
skeletons>
Here comes the familiar bit (I've been reading your web site ). I bought a
Goniopora sp , a green one and did everything wrong I now think. i.e. I moved it
about to find a spot it liked and then after I sorted that and it started
opening about 3 inches in length (It looked lovely) I decided maybe it might
like more light so I added two reflectors one on the HO fluorescent nearest to
it and one on the actinic blue. The other HO which makes up my lighting I left
alone. The next day, the flower pot started emitting this strange brown grungy
stuff that floated and swirled around it , I brushed it gently away but it came
back with a vengeance through the night.
<AKA brown jelly... a common necrotic condition with Goniopora among other
scleractinian>
My LFS said it was either expelling its mucus which they apparently do or it was
dying.
<Goniopora do not expel visible mucus... the animal was clearly dying>
I gave it a fresh water dip as they suggested and put it back in its place in
the tank.
<no qualms here... it is a virulent condition that must be addressed swiftly.
Iodine baths too may help in the future>
I noticed that it looked like all the little flower tentacle places were empty
like a white honeycomb , only a small part of the top was still green. This
happened in two day's would you believe!
<I have seen it many times... a highly infectious condition. Even the basting
or blasting away of tissue in the tank is dangerous... if/when the infected
tissue drifts and settles on another coral it can spread the infection. Tends to
run its course fast though. Sick corals and fish should always be quarantined in
a proper hospital tank for 4 weeks to prevent this very thing. You may very well
learn a very hard lesson here, I'm afraid. Adding fish to any display without QT
is a game of Russian roulette with living creatures. Please take heed and make
your next investment in a simple QT tank instead. Do browse the FAQs here for
plentiful tips on hardware and husbandry (crash course: bare glass bottom,
conditioned sponge filter running and waiting in main display, plastic pipe or
other sterlizable ornament, glass cover yes... but light dim perhaps, etc>
I then saw that the rest of the tank was looking sickly to. My Leather Coral
which had looked lovely is now unrecognizable and has whitish brown 'bad' places
appearing on it
<carve these necrotic areas out ASAP with a razor or scissors if there is to
be any hope of salvaging pieces or the parent. Tank needs strong water flow,
small frequent doses of iodine, aggressive skimming and extra water changes>
and my mushroom corals and mushroom anemones also look sad.
<not much to do with corallimorphs... must run its course short of above
improved husbandry>
Also my carpet anemone is screwed up most of the time but it still ate it's
frozen (thawed out) fish two days ago. I have had this anemone for approx 6
weeks ,I now know you will say it is dyed because it is blue but one of my fish
books say's you can sometimes get blue so I'm hoping this is it's real
colour.
<I agree that some natural blues occur... but my bigger concern is that it
has absolutely no place in a reef tank. The size of this animal as it grows and
more importantly the severity of its "invisible" warfare (allelopathy)
on corals cannot be understated. This animal will likely plague you until it
gets put into an appropriate species tank alone. Else, I fear you will go the
way of hundreds of aquarists I have seen through the years... the tank may
appear to fare well for 1 or even 2 years with it in residence... before the
tank reaches a critical mass (concentrated noxious compounds or any one of a
number of other complications). The tank will "crash" again>
I'm afraid as the Goniopora was again smothered in this gunk I disposed of it
like the LFS advised.
<QT tank next time to try so save these living and precious resources...
spare the animal and the display with good husbandry>
Is my entire tank doomed,
<not at all for the Goniopora reason... the infection will run its course
within 2 weeks... likely sooner>
what can I do to save the rest of the inhabitants which consist of 2 clowns,1
gramma,1 firefly and 1 red hawk fish, I also
have 6 red legs,3 sally Lightfoots 1 cleaner shrimp and 6 turbo snails in this
tank. I Know how fond you are of skimmers and I have them on both tanks, but
don't ask what type is on the invert tank!
<any type that produces a full cup of dark skimmate daily is a fine skimmer
to me. Especially with the anemone you are keeping... critical>
I hope it's o.k. to mail you from England but we don't have anything like your
webpage here.
<it is a great pleasure to hear from friends like you from all over the
world!>
I have discovered how little I know from you. Any help you could offer will be
greatly appreciated.
<no worries, my friend... we all learn in time. You will only be faulted for
ignoring or not learning from your experience/mistakes>
Many thanks for your help in advance. Jenny
p.s. I'm mailing from work, I don't have my own e-mail set up yet and I had
problems using netscapes e-mail facility, hope this is o.k. with you.
<our pleasure... best regards in your endeavors. Please do continue to help
yourself by researching animals before you buy them with an intelligent
consensus from several sources... not just one/LFS. Kindly, Anthony Calfo>

Re: Help! Has my Goniopora sp contaminated my tank
Hello again !
Thank you so much for your prompt reply to my e-mail below. I wasn't in work
yesterday and so have only just got your reply. I will be a lot more careful
what I buy in future, I feel so guilty now!
<alas...we all make these mistakes... no worries. Just resolve not to repeat
them as such <smile>>
The Leather coral seems to have made quite a dramatic recovery, it has perked
right up and has all it's (polyps?) extended. Should I still cut out the 'bad'
bits or see what happens? i.e. it seems to have
formed a scab on one of the places and that is almost coming off , Do they heal
by themselves sometimes?
<good symptoms indeed (especially the polyp extension), but once a coral has
a necrotic infection, it usually does some damage. Do explore without touching
the coral: take a turkey baster and blast water at the wounds to see if soft
tissue is still dying. If so, then do cut out the bad parts. Else, baste with
blasts of water daily for several days to help the healing process. Some people
even take a soft toothbrush and gently scrub into good tissue to remove
decay>
All your comments were much appreciated and I will act on them ASAP. I have a
2ft tank in the garage, is that big enough for the carpet Anemone?
<probably for a while... and do give nice bright reef quality light. And just
as importantly, do feed it several times weekly. Feeding is critical with these
large aggressive anemones. Their adult size is several feet across in the wild
but they live many decades (this may be an understatement... some have
postulated that they have no defined lifespan and than many large species in the
wild are over 100 years old... this is part of the reason why so many folks
discourage the taking of this animal from reefs for casual aquarium captivity as
opposed to fewer numbers for study. Long life and slow recovery from collection
in the wild).>
Can he still have his 2 clown fish for company, they seem to love him to bits!
<that sounds very fine... it will make a lovely species-specific display. Its
great to see your willingness and empathy to provide well for this animal. It
sounds like you might need and enjoy some book recommendations. There are a
couple of good books on anemone and clownfish (a Tetra book on Host Anemones and
Their Clownfish, as well as a great book by Joyce Wilkerson on raising
clownfish. For your coral... please do consider Eric Borneman's excellent
Aquarium Corals and for easy reading reef aquarium husbandry and coral
care/culture, my Book of Coral Propagation.>
Thanks again Jenny

Chelmon rostratus & Christmas Tree Worm
Hi Robert!
<Steven Pro in today. Bob is in Arizona making a pitch to one of their local
clubs.>
Always Hervé the French aquarist owning the flounder ;-)
I'd like you to confirm what I'm thinking : I have a Chelmon rostratus in my
tank and someone would like to give me his Porites with "Christmas tree
worms" but I'm afraid that the worms could become a great meal for my
Chelmon!
What do you think about that?
<Yes, definitely would become food. The Porites and Christmas Tree Worms are
popular, but fare rather poorly in captivity. The Porites are generally VERY
bright light corals and the worms are difficult to feed. -Steven Pro>
Alveopora Worm?
Hi Bob,
<Anthony Calfo in your service>
I have an Alveopora that I bought about 15 months ago. For a year it was doing
fantastic. Then suddenly it started to fade.
<commonly from excessive light and more often from inadequate dissolved
organics (source of nitrogen)>
I was trying to determine why. I read a very odd thing on a different site where
someone noticed that there was a worm that would live on the same rock as the
Alveopora. Several people commented that they saw the same thing. I am sure I
saw one as well. Well, about 3 months ago, I moved, and I believe that during
the move this worm died, as I haven't seen it in a long time. Now, the Alveopora
is fading.
<if it is "fading" in the sense that its color is paling the worm
absolutely had nothing to do with it. Impossible. Changes in pigmentation are
caused by many things... but never a worm. Temperature and salinity stress
easily, but again... usually excessive light (NEVER direct MH or PC light for
Alveopora) or lack of nutrients in a well skimmed tank>
I also read that if people kept several of them in a clump, they tended to do
better,
<yes... seems to be some truth to this>
I would assume that has something to do with the worms that live or die sharing
responsibilities across the rocks, or something like that.
<the dynamic is not yet clear>
I just wanted to get your thoughts on the theory, and see if there is anything
that can be done for a receding Alveopora.
<if your nitrates have been near zero for the last few months, your coral is
simply starving. This animal is not strongly photosynthetic but cannot feed
organismally (particles of food). It simply needs dissolved nutrients. See
Knop's recommendation for making a nitrate solution to feed clams and
invertebrates in his Giant Clam book. >
Thanks, Steve
<best regards, Anthony>
Goniopora and Carpet Anemones
Hello Bob and Crew!
<cheers, mate>
I purchased a flower pot at my LFS with polyps retracted.
<Doh!!!>
The sales clerk assured me it would open fine.
<Steeeeeee......rike, one!>
By the 5th day of half polyp extension in my tank, I grew weary. Upon closer
inspection, using a magnifying glass I noticed between the polyps on the
hexagonal walls very slight browning or tissue decay.
<very common... the way of most Goniopora soon after import>
Without hesitation I removed the GONI into the QT where currently a small school
of green Chromis sit in wait. Didn't want even a slight chance of spreading
bacteria.
<hmmm... a good move for the tank, but a bad move for the GONI... I suspect
that you know already that the GONI should have gone through your QT first. For
the benefit of others reading the post, the dilemma here is that a now clearly
stressed and infected coral must now accept the burden of adapting to at least
the fourth water quality in two weeks (wholesaler to pet store to display to
QT). The change in lighting alone is extremely stressful and 4 such changes in a
healthy coral can sometimes be fatal. Still... I do agree with the extraction to
prevent the spread of infection>
I proceeded to read your FAQs on flower pots. Basically don't buy flower
pots!
<true for most my friend... although for anyone interested in keeping these
beautiful corals in a species tank, please browse I recent post that I proffered
to an Australian message board on Gonios: http://ozreef.org/rtaw/ubb/ultimatebb.php?ubb=get_topic;f=1;t=003878
>
But what should I do with this specimen?
<leave it in place for at least 4 weeks if it survives... spike the tank with
small daily doses of Iodine (variations on Iodine dips can be found in Eric Bs
Aquarium Corals book and my Book of Coral Propagation). Also, small frequent
water changes and the safe use of ozone can be very helpful>
Its not doing that bad because to be honest I couldn't really see the decay
without the magnifying glass.
<gently siphon that decay out if possible... it is highly infectious>
There is no light on the QT and I have an Asfur Angel arriving tomorrow that
will be placed in the QT also. Can they both be in QT?
<the Asfur may pick on the coral... but the coral will not bother the Asfur
Angel>
Maybe the Asfur will find the Flower Pot quite the "welcome to your new
home" feast.
<sure..., "Welcome to your new home...here, have a rotting coral to much
on!" :) >
I will be removing the Chromis' to the main tank today. Moreover, what
interested me while reading the FAQs was your warning against having carpet
anemones specifically "blue." I have had my blue carpet which is from
Tonga for approximately 10 months now.
<glad to hear it but you need to understand that some such animals take more
than a year to starve to death when the net daily deficit in "food"
translocation of carbon from photosynthesis or from organismal feeding) is only
a few percent. 10 months is really not much of a feat yet. Still... with weekly
if not daily feedings and very bright reef light you can indeed have this
anemone for many years. They live for decades in the wild and are suspected of
lacking a defined senescence (old age). Read more about coral/anemone
feeding/starving here: http://www.wetwebmedia.com/fdreefinverts.htm
and here:
http://www.wetwebmedia.com/growingcorals.htm>
Its perfect and I noticed its sting to be a little more "painful" then
its green counterpart, which both are shared among 3 Maldives clowns. I don't
think the blue carpet was the reason for the flower pot demise....
<heehee...hahahha...hehehhehe.....ahhh, well... if you say so :)>
but maybe....The blue carpet likes to wonder around but I have it trapped
between live rock walls so it basically crawls up and down and side to side
moving a lot but getting nowhere. Are there any future consequences to my SPS's
and other inverts outside of direct contact?
<yes... and literature abounds on this subject. Mist chemical warfare among
cnidarians occurs without touching (shed nematocysts and the like). Even a 50%
water change every day still leaves 50% of the concentrated noxious elements
behind and no one can say that carbon or skimming pull out enough. This is why
unnatural mixed of SPS, anemones, soft corals, etc are not recommended. Better
to keep like animals together for their increased familiarity and tolerance>
What can I do to avoid these problems sans removing the carpet completely.
<remove the other corals/cnidarians and leave the carpet...heehee>
I don't think the Clowns would like that too much. One last thing...do I need to
freshwater dip the Chromis again before placing in main tank?
<if they have been through a full QT (4 weeks) no need>
I had some deaths when I first got them but these last 10 have survived almost 2
weeks without any apparent signs of disease.
<it would be better to go for the full 4 weeks especially because of those
deaths... no guarantee that they aren't still carrying and something pathogenic
won't flare up for the stress of the move>
Thanks Again! Dennis
<best of luck, Anthony>
