Corals as Carry-On? - Tubastrea Tube Coral Shipping Method 03/31/07
Hello,
<<Howdy>>
I tried going to the forum but registration was unavailable.
<<Hmm...seems to be working now...>>
I have a quick question.
<<Ok>>
I am traveling on Business in Florida & I stopped at a LFS & was interested in a
very nice Tubastrea piece to bring home with me.
<<Beautiful organisms>>
My question is what is the proper shipping method to bring it back to NJ?
<<Mmm, go to the store just before you depart if possible...tell the LFS what
you plan and ask them to triple bag the coral. They might also help you with a
small insulated container to carry/transport it in. Otherwise, I have found a
small insulated soft-sided lunch box works well for transporting a few bagged
corals as "carry-on" luggage>>
Should it be fully submerged in water, or can it be wrapped in damp paper?
<<Would need to be submerged...in my opinion>>
I am also concerned that if submerged in water I will not be able to bring on
the plane due to the liquid restrictions.
<<A good point...I didn't face this restriction last time I transported corals
as "carry-on." I very much suggest you contact the airline and explain what you
propose to do. If you are very much attached to this particular coral, you may
want to ask the LFS for assistance with shipping it back as "checked" baggage
(will need to be packed/protected/marked well)>>
Appreciate any advice that you can give. Thanks.
Jorge
<<Good luck...and please do let us know what the airline's response is. EricR>>
Terminological confusion ... A-hermatypic...al 2/22/07
Hello Crew,
<John>
I'm curious to have a precise and accurate understanding of the
term 'ahermatypic', if for no reason other than to impress and amaze
the less-knowledgeable.
<Heeee!>
The term is used in differing ways by differing people, all apparent experts.
<Love that term... Ex= "previous", Spurts?>
On the WWM site, the term seems to be
consistently used to refer to those corals that possess no zooxanthellae.
<Mmm, yes... a common "understanding"...>
But, for example, fishbase.org explicitly defines 'ahermatypic' as "non
reef-building" (this at
http://www.fishbase.org/ Glossary/Glossary.cfm?TermEnglish=ahermatypic).
<This is the more formal... correct meaning of the word>
Even more confusingly, on the NOAA (National Oceanic and
Atmospheric Administration) website (specifically at
http://www.photolib.noaa.gov/reef/reind4.htm) Tubastraea is called
ahermatypic in virtue of its having "no zooxanthellae algae in tissues and
[being] non- reefbuilding". I sure hope my tax dollars aren't financing
the spread of ignorance...
<Heeeee! Too late... D'oh!>
I can tolerate a lot of confusion, but this is really getting to me!
Now, I'm sure the WWM crew is correct, but could you say a bit about what makes
your usage correct (by reference to etymology, perhaps, or terminological
history).
<Careful here... I am a huge fan of "word origin" discussions, games...>
Thanks for any information, and thank you very much for maintaining WWM -- it
has been a valuable source of information on all aspects of the hobby.
-John from Minneapolis
<Well... I'll give this query a stab... A= ablative, Lingua Latina, meaning
"away from"... hermatypic corals! Okay, am cheating... (means "like stone"...
see here, young man:
http://phoenixandturtle.net/excerptmill/Gasper.htm) these are the
Scleractinia that don't produce (yes, with/in conjunction with those
endosymbiotic (Shades of Lynn Margulis!) algae... those large, clunky carbonate
skeletons... giving them (as it turns out, falsely) the big credit for "reef
building" (a few algae, mostly rhodophytes deserve the props here)... Enough
already? BobF>
Again About Coral Species... Reef-building and Non-reef-Building ...
number of species 2/4/07
Hello Bob,
<Greetings Hien, Mich with you today.>
I've asked you once about coral species and now I'm in trouble again. How many
true coral orders you think? I also read some documents say that there are over
800 species of reef-building coral in the world.
<Reef-building corals are corals that have a skeletal base composed in part of
calcium. There are corals who are totally soft without a skeletal base, just as
there are fish who lack true bone i.e. sharks, eels and rays.>
This coral has a calcium base which appears white under the overlying coral
tissue:
http://www.wetwebmedia.com/fungiidae.htm
If the coral it dies it leaves this base behind.
This coral does not have a calcium base: http://www.tolweb.org/tree/ToLimages/pseudocorynactis.jpg
If the coral dies it leaves nothing behind.>
Does it mean that the total number of coral is over 800?
<Yes, far more than 800. "There are more than 2,000 species of living coral
presently classified, with probably as many yet to be named." pg 24 Aquarium
Corals by Eric H. Borneman.>
I'm really confused with different documents I've got!
Look forward to hearing from you soon,
Hien
<Hope that helps. -Mich>
New SPS Frags... Long Shipping... What To Expect? - 12/31/05
Hi all...
<<Hello>>
as has been stated by many, you have an awesome site, no fluff all info.
<<Thank you>>
I have read much, but not all of the site, haven't been able to find an answer.
<<ok>>
I just acquired some Acro frags 1 yongei and 2 tortuosa (sp.?).
<<Correct>>
Thanks to shipping problems they were in transit about 40hrs.
<<Uh oh!>>
They arrived white, little or no apparent color, no polyps yet.
<<Expelled their zooxanthellae...or worse...have complete tissue loss.>>
My fears about ammonia in bags and alkalinity of tank water led me to introduce
them to the QT tank after temp adjustment.
<<Smart>>
I'm acclimating lighting using vinyl screen layers.
<<Smart again>>
On intro to QT tank frags had filaments of slime but no other indications of
life.
<<Not unexpected...>>
Don't expect a miracle here but what if anything should I expect from these
frags if water parameters, lighting and flow are optimal, which I think they
are. At what point should I give up on them in your opinion.
<<Mmm...both species of coral have quite visible polyps, if you don't see any
evidence of these after 48 hrs. I think you can assume the worst. You might
also try viewing the frags under some magnification (jeweler's loop/magnifying
glass) to see if you can determine if there is any flesh on the skeleton.>>
This is my first of many cracks at SPS so would like to not overreact.
<<You're not overreacting...40 hours in transit/bleached condition is cause for
concern.>>
Steve
<<Regards, EricR>>
Coral block 12/29/05
Hello,
My name is Ray, I live on Maui in Hawaii, on our beach there are tons of dead
coral stones, most are rounded with age. A fellow that moved to the mainland
use to make sculptures from the coral after he crushed it and mixed it with
something. ?????? anyway the sculptures were extremely hard. Like bricks. I
was wanting to cast some rectangular bricks (blocks) to line my flower
gardens. Would anyone there know what mixture would work good with the
coral? Or perhaps you could point me in the right direction as to where I might
find out. Thank you.
Aloha,
Ray
<Likely the best route to go here is to treat the crushed dead coral as
aggregate and sand... use about one sixth of their volume in "white cement"
(plastic if it's not much more expensive) to make "concrete" for casting. Bob
Fenner>
Re: coral block 12/29/05
Bob,
Thank you so much for responding so quickly. I hate to seem like a dummy,
but this is my first time and I want to be sure I'm clear on what your
saying.
<Sure>
When you say use one sixth of there volume, does that mean use 1
part crushed coral and 5 parts white cement?
<Sorry re the lack of clarity... five parts of the crushed coral (as in three
parts crushed rock and two parts sand to one part cement for a "regular"
concrete mix) to one part cement>
That seems like it would be a
heavy block, I remember the sculptures Mark made were very light. Just
wondering. Thanks again for helping me.
Aloha,
Ray
<Glad to proffer my opinions... have seen these blocks in many places in the
world, including processes for making "clinkers", CaO from CaCO3/coral rock
itself (basically heating up in the absence of oxygen/air) to make the cement as
well... Cheers, Bob Fenner>
Transporting Large Corals 1/16/04
I have a very thinly branched Acropora coral, which I'm happy to say is
growing very quickly. I have fragmented the coral several times. Some of the
fragments themselves have grown quickly as well, one of which is now 8"
across. I'm going to give the corals to my LFS (about 30 minutes away), but I
can't figure out how to transport them without breaking them.
<use a large cooler (Styro if possible) for each coral (never mix species in
transit) and line it multiple times with a full box plastic liner (bags). Fill
the bag with sliced or shredded plastic before adding enough salt water to cover
the coral. The specimen set in place in this bed of shredded plastic is fairly
well cushioned. Some people instead wrap the coral in plastic sheeting before
sinking it... but this often traps air bubbles which over all are a problem or
at least annoying)>
The smaller fragments are easier because I can float them upside-down in a
bag.
<correct>
Do you have any suggestions on how I might be able to transport the larger
ones? I'm afraid that the weight of the larger ones, including the rocks that
they are attached to, will be too heavy to float with Styrofoam. Any
suggestions you might have for me would be great. Thanks!
<best of luck! Anthony>
Questions on new corals 10/29/04
Hi Crew....great site! I have been reading your site since we
started our 75 gal reef tank about 6 weeks ago. Finally the cycle has
completed and all water parameters are great! We put a few fish and
coral in a few days ago. I got a hammer and pearl bubble both that I
put mid level in tank on some LR. Green brain WAS at the top per the
guy at my LPS, but reading thru your site today ran across some info and it said
the brain should be down at the bottom on the sand, so that is his new home.
<ah, good to hear>
Hopefully he will like this spot better and actually open up some, we have yet
to see it do this.
<no worries... many corals take a few weeks or even months to fully express
polyps on acclimation>
We also have a toadstool leather, about 4 inches across. I have look
thru tons of info on your site and still can't find out the best placement for
this coral.
<they are very adaptable... strong water flow is more important for it
here>
I thought toadstools had stalks but this one doesn't. Again the guy
at my LPS said to just put it in the sand and it will attach. Could
you please help my in placing it?
<anywhere in the top 20" of the tank ;)>
Also didn't realize I had to "hand" feed corals!?
<yes.. your bubble, hammer and brain at least need fed 3-5 times weekly.
Small portions of finely minced meaty foods. The leather does not need target
fed>
More info I've learned from your site. So today I bought some Mysis
shrimp and zooplankton.
<perfect>
I will try later this evening to see if I can get the hammer, pearl, brains and
sun polyp to eat. Is it correct that I don't have to "hand"
feed the toadstool?
<exactly! Thaw the meat in cold FW... then strain and soak again in tank
water then feed as a slurry (turkey baster, pipette, etc)>
Thank you so much for all the time and energy you put into this site! Beth
<very welcome my friend... best of luck/life to you. Anthony>
Toxic corals? 9/30/04
Hi please I need help, I am very confused, all corals are toxic right?
<hmmm... depends on your perspective/meaning: regarding filter feeding?
(stinging nature of cnidarian animals)... regarding allelopathy (chemical
warfare against encroaching organisms)... poisonous nature if ingested or
harassed??
what corals are more toxic?, what corals are less toxic?,
<variable as you might guess... and as per the above definitions>
can a coral kill a human really?,
<yes... more than a few can. Notably... palytoxin in Zoanthids. A historical use
by Hawaiian natives, et al when tipping spears for mortal combat>
I wont full my aquarium with corals, but I don’t wont go to the hospital or die,
please help me, what corals you know not are dangerous?, thanks you.
<this is a small concern with good husbandry/handling... really. No worries with
careful and proper handling as you do household chemicals, medications, fumous
agents at work/home, etc. Anthony>
Questions about importing
Hello Bob. How's it going? My name is Brahm, I met you a while back at
Octopus's Gardens down in San Diego (Before Jason moved to Florida).
<Ah yes... and he may be coming back... maybe just flying with the hurricane
winds!>
We
talked about my thoughts on opening up a store, well things are looking
like they are moving in the right direction, but I had a question, and I was
wondering if you might be able to help point me in correct direction. I met
somebody online, in Melbourne, Australia. Who came across some very nice
Favias, and Acanthastreas lordhowensis & hillae. They are going to ship them
to a friend of mine in New South Wales who can hold them for.
She is also willing to ship them to me, but we aren't quite sure what we
need to do on the Australian side to obtain the proper permits for a one
time shipment if such a thing exists.
<Yes... they do... there are some Customs forms to file and CITES permits...
that hopefully can be filled out on the Australian end and used all the way
through to (LAX?) here. A very good idea to actually see, ask around to see if
you can "piggy back" your small order with someone in the area (LA likely) who
will umbrella your few boxes with their "can" (airfreight container)...
otherwise the cost for individually doing this is going to be quite high. I am
going to cc a friend in the trade, Barry Neigut of Clamsdirect.com (who is, or
has just opened a retail outlet in SD) and ask him for input here. Maybe he
knows someone who will co-op your shipment.>
What would be the best means to
export these pieces from Australia?
<The best? Don't know what you're looking for here... doubled 4 mil poly bags,
clip closures, styros, cardboard liners... in cargo container quantities, with
you receiving ASAP from customs, your freight forwarder... IF you have NOT done
this before, DO go, chat with people in the trade who DO on a regular basis. Am
going to cc another friend in the trade, Eric Cohen, who owns and runs Sea
Dwelling Creatures in LA, and ask him if he'd help you here... Importing aquatic
livestock is "not for the feint of heart" or "light of wallet" to put this
mildly... "Things" go wrong... all the time... shipments delayed, re-routed,
time lost and lost and lost... disputes with carriers... DOAs... You REALLY need
a large, going business, holding facilities... to justify doing what you
propose... unless you're "just experimenting" here or hoping to get some unusual
specimens... all this is going to cost you a few to several times what these
organisms will/would cost you by ordering, picking them up at a distributor...>
Are there any coral export facilities
that I might be able to go through (that are trust worthy with such rare
pieces)?
<Yes. Ask Eric here>
Or would I be better of obtaining the permits on my own. I've
talked to Dave over at Pacific Aqua, and I think I can use his Cities on
Stateside, (or if you can point me to a broker). I would appreciate that...
<This is very nice of the folks at PAF... if they will co-op with you and you
feel comfortable dealing with them. They also definitely know what they're
doing>
Although I'm not too worried about the cost, I would like to look into maybe
offsetting some of the expense by bringing over a larger shipment of other
items (SPS, or hopefully more Acans if I can find them) which I can resale
to diffuse the cost.
<Bingo!>
But my main goal is just to get the Acanthastreas
lordhowensis as I have been doing quite well with propagating the current
pieces that I was lucky to either trade for, or pick up at LFS mis-labeled
as Blastomussa wellsi
<I see>
Included are a few pictures of the actual pieces. There are a total of 10.
Thanks for your time.
-Brahm Goodis.
<Glad to be of assistance. Bob Fenner>
Re: Questions about importing
Hey all,
<Hi Eric, thanks for chiming in>
From what I understand here, the corals are coming from Australia. To make
this conversation brief, it's illegal to export corals from Australia.
Unless you can get a cites permit from the government office that works with
cites
permits...I think you are out of luck.
If you find a way (a legal way), please let me in on it and we would be
happy to assist you and give you your best chances to get the corals here
alive
and economically.
Best regards.....HI BOBBIE!
Eric
<Thanks mate. See you about. Bob Fenner>
When can I add corals?
Hello and good day to you.
I have recently set up (4 wks.) a 75G tank as a reef tank and have been running
water parameter tests weekly.
This tank has a refugium w/ macro and sump w/ PM skimmer.
I would like to know if you think that this tank is ready to stock with 2 small
corals that I have my eye on
or whether I should wait a few more weeks.
My readings are:
Temp-78.6
SG- 1.025
PH- 8.2 (tested with lighting off since overnight)
Ammonia-0
Nitrates-0
Nitrites-0
Phosphates- < .25mg/L
Calcium- 360mg/L (I think this needs to be higher- target 400-450?)
Should I use B-ionic or similar product? << Not bad. Depends on what you want
to keep, but adding little can't hurt. >>
KH- 130mg/L
I just went through the diatom stage and it is almost gone at this point now
becoming green.
I put 2 bonded false perculas in the tank yesterday (had to save them from a
LFS)
and only plan on 2 more fish- likely a yellow tang and some type of goby or
blenny for substrate duty.
Thank you very much for your help and your honest opinion.
<< Well the water seems fine. But that usually isn't a problem anyway. I've
set up aquariums and put corals in them on the first day. The main question is
how is your lighting. That, with how much live rock you have, is the key to
adding corals. So if you feel you have enough light, then I think you are ready
for corals. >>

Tubastrea Coral
Hello, <Hi Alex, MacL here>
I'm super happy to say that my beautiful flower coral is doing AWESOME!!!! Thank
you so much for all the advice !!! And I'm also happy to say that I'm going to
start a 10 gallon tank full of only Tubastraea sp!!! Man I'm in LOVE
with these corals!!! I have been reading on small tanks on the web-site. Is
there any advise you can give me on this??? (PS) Just a reef tank no fish
<I'm so glad you are loving them. Its really important to watch the levels in
a tank that small so be sure to check it frequently.>
Thanks again!!!
Coral Excretion? 6/15/04
Hi again, cant find satisfactory answer in archives after two hours and
various detours from subject.
<a nifty way to learn>
My brain coral is exuding a brown hair like substance from little openings in
the valleys between its ridges which are rather like very small volcanoes in
appearance. Please reassure me, is this it excreting waste matter from its
various mouths as I suspect it is?
<quite likely yes... have you been feeding it or the tank well? If so, indeed
this may be the scoop on poop>
Or something much more sinister?
<the only other thing commonly possible would be the expulsion of zooxanthellae
packets if the animal was light shocked. But that would be rather obvious - pale
and stressed coral under bright lights or suddenly increased water clarity (as
with sudden use of carbon in yellow water after many months without>
I have recently (this week) learnt to target feed it Mysis shrimp after a period
of unknowing starvation (three weeks or so) during which it still opened nightly
and occasionally over the day.
<ah, yes... good to hear you are feeding. This is a hungry coral>
Seems other wise happy but I realize this can be deceptive. Fed it twice a day
for three or so days to boost it up after having starved it (unknowingly) now
down to once a day. Is this too often to feed it?
<very nice if you want fast growth... but a few times weekly would be enough>
How often should I feed it? I turn off pumps first thing in the morning before
lights on while it is still all open and target feed with plastic syringe (no
needle) then feed fish so they leave it alone and it seems to get heaps, all
ridges swell, soft and trap Mysis. How long should I leave it to eat before I
turn pumps back on which invariably blows the shrimp away for fish to pick up in
current? Five minutes/fifteen minutes/half an hour?
<tough to say... and do invest in an electronic relay switch that automatically
turns power/pumps back on. Human error is inevitable in time and if you forget
to turn the pumps on for an afternoon, overnight, etc., it could be disastrous.
10-15 minutes sounds fine to me for feeding opportunities>
Thanks heaps.
<we have piles of it. Best regards, Anthony>
Corals are adapting
hello all, just thought I'd point out a cool thing incase none of you saw
this. On Sunday on Yahoo scientists report that the coral reefs are
making some comeback ,after years of higher than normal temps. Awesome
, just awesome......looks life are stony friends are stubborn to
extinction as long as we stay involved. Adapting to higher temps to
survive...NICE!!! check it out , pass it on....later.

<Good news indeed... makes sense that organisms that have been around for
hundreds of millions of years, through ice ages, reversals of poles, whatever
undid the dinosaurs... would be able to put up with the current affair. Bob

Bubble coral 3/19/04
Hi Sorry to trouble you
<Hi Sandy. No trouble at all! That's what we're here
for.>
but I have had a reef tank up and running for 6 months or so - all seems well,
pulse coral that is propagating itself - mushroom that we have propagated and
they seem happy. I have a pearl bubble coral that once a week enjoys a small
piece of shrimp that it devours. Today just as it was shutting down for the
night, it's mouth became apparent and it seemed to purge a large piece of its
insides out of the mouth, it then shrunk back inside the mouth but did this
several times before it settled for the night. Is this usual? Many
thanks Sandy
<This sounds normal. Corals only have a mouth, and it has to serve
as the way food comes in and waste goes out. If the coral expels
large pieces of undigested food, the pieces may be too large. Bubble
corals are pretty voracious though, and should be able to handle whole shrimp or
silversides. Large polyped corals will often expel excess
zooxanthellae. This usually looks like brown stringy snot. Some
coral will also occasionally expel and reingest mesenterial filaments (digestive
organs). This can be a sign of stress, but if it passes and the coral
returns to normal without any other signs of ill health, it is nothing to worry
about. Best Regards. Adam>
Acclimating corals - 2/5/04
How's it goin' crew? <Hey, good and you?> When acclimating new corals
into a new display's lighting parameters; Should they start off at the top or
bottom? <Oh, well at the bottom as far away as you can get from the lights.
Then every few days to a week, move it up a few inches or so. Depending on the
coral, you could even move it to its location in the tank. There are all kinds
of exceptions here, but the usual feeling is that once the polyps are no longer
retracted then you can start moving it around. I know, not a great answer but I
hope you get the idea. There is more info here: http://www.wetwebmedia.com/acclimcoralslight.htm
Thanks for the question. ~Paulo>
Ubiquitous Lighting Questions, and the New Coral Stocking Question
Hello all.
As I look at your site daily for the FAQ's, I find more and more valuable information. I can not say how valuable your perspective and
experience is for those in the hobby.
<Thank you!>
I have had several tanks over the past few years and have gotten out and back in.
In the past my tanks have been FO. This time after taking my wife with me to our LFS she wants to have some coral. The plan is to add what you
could call easier coral like star polyps and leather corals. To give a little back ground my tank is a 125 Gal with 170 pound LR for filtration
and has been running for about 6 months. The lighting currently is 2 140 watt (280 total) VHO URI bulbs (1 super actinic, 1 actinic white).
I guess my first question is should I double my lighting?
<Doubling your lighting (4x 140wt VHO's) would be an excellent start, especially
when you consider keeping some of the light demanding scleractinians (stony corals).>
The reason for my question is about adding coral to the tank. I understand the acclimation process and about slowing increasing the
lighting, but I have searched everywhere and cannot find anything about the number of coral that can be added at a single time. I know that
with fish it must be very slow. Currently I have only 3 fish in the tank (2 blue damsels and 1 Sailfin). The main reason that I am asking
is that I have seen several paces that offer deals when you purchase multiple corals at a time, for an example like 5 Corals for $99 or even
9 corals for $99. Since all of the places are close to my house I could pick the coral that I want. This seams like a good deal from a monetary
perspective, but I am not sure if it is a good deal from a tank perspective. Can you add this many corals at one time if they are small
to mediums sized or does size of the coral even matter?
<Corals produce very little biological load so it would be no problem to add a large amount of coral to your tank at once. I've seen the 9 for $99.00 deal, and it definitely is a good deal. To answer your second question, size will matter, although as I stated above, corals put out such little biological load that it would be fine to add a large amount at one time. I would first make sure your tank can support corals before you go ahead and spend $100.00 on live coral. You may want to add a few easy to keep corals to your tank first, such as mushrooms, zoanthids, etc. If these corals prove to do well, you can move on to other species of coral.>
Take Care,

Thanks for your help and perspective. I have been reading stuff from Bob since FFExpress
day's and greatly appreciate his opinions his book
the Conscientious Marine Aquarist is one of the best book I have read on the subject. Also I wanted to let you know that I love the Reef

Cloudy Water (12/22/2003)
WWM, <Steve Allen again tonight>
I received my Alveopora, bubble coral and yellow polyp colony on Friday from http://www.
liveaquaria.com I slowly acclimated all three to the
tank. Surprisingly, they all started to open after only being in the
tank for a short while. All of Friday the corals were
fine. Saturday everything was great. Now today, Sunday, I
woke up to a SLIGHTLY cloudy tank. Everything appears to be
great. All corals extended, all fish swimming, nothing dead. Tested
ammonia, pH, nitrate, nitrite, all good... <I hope that means zero on ammonia
& nitrite.>
Why did my tank all of a sudden get cloudy? It's not totally cloudy,
just not completely crystal clear like usual... Do some of these
corals "spawn" or something like that. <unlikely>
<There are a number of things that can cause some clouding in the water.
Possibilities: precipitation if calcium/alkalinity out of whack, dissolved
organics, microbubbles, fine detritus or sand dust, bacteria, and certainly a
lot of other things too. Are you using any mechanical filtration. Check on WWM
by searching on "cloudy water" for some insights.>
Thanks <hope this helps>
Coral Color Morphs 11/13/03
Hi Bob Fenner,
<Anthony Calfo now in his stead>
thank you very much about the delightful and informative answer you send
yesterday. Corals is the one of the most beautiful animals in the worlds,
especially the brightly colored ones.
<indeed... they are living treasures to behold>
Just only last week, I saw several types of delicately sculptured Acropora coral
(it was Acropora lovelli) in a cybernetwork database named "CoralSearch
Search Page". When first I see them, the colors looks dull and pale. But
then, when I see in another webpages, their color bursts into bright spectrums
like blue, teal, or even pinkish.
<there are many reasons for this... artifacts of natural lighting and film
with underwater images... manipulations of digital images... stressed and
shipped animals (pale) versus established ones in aquaria, etc>
So does another corals: Naturally yellow ochre dull Acropora clathrata to
spectacular pink captive Acropora clathrata; Naturally stale yellowish Acropora

Acropora chesterfieldensis to stunning neon green captive Acropora
chesterfieldensis and so on. Their colors seems to boosts as the sunlight
replaced by metal halides. Why? Sincerely, Anargha
<on the contrary, my friend... most corals are more colorful under natural
sunlight. It just is not always apparent to us from wild-photographed specimens
(aspects of film/lighting) or from the condition that stressed and shipped
corals arrive in. Good halide lamps at best help the coral to recover some of
its natural beauty... but nothing compares top the sun and natural sunlight over
coral. Many aquarists grow coral under skylights and near windows for this
purpose. Anthony>
Torch coral I think has necrosis??? 10/7/03
Hello, thank you so much for your help.
<our pleasure>
One of the polyps on my torch coral had been opening for only three hours during
the day (for about a week and a half). It is the lowest polyp from the
light and contained the sweeper tentacle. I then placed a bubble
coral pretty close to it, however never touching, could it of got stung and
brought it over the edge? I have a 32 gallon.
<yikes... yes, easily. The problem with coral warfare is as much chemical as
contact (noxious exudations - allelopathy)>
It has now begun to not open and some sort of brown substance is on
it.
<it has a highly infectious bacterial infection. Please remove this coral to
a quarantine tank (and always use a QT tank in the future for all new purchases
without exception). Else, break off the necrotic branch and discard>
I only feed the torch coral once a week, and I feed it Kent's Zooplex.
<I do believe you could be feeding it a much better diet (fresh thawed meaty
foods like mysids, Pacifica plankton, etc) and more often (3-5 times weekly
minimum)>
Is their anything I can do to save the polyp if it is necrosis?
<not the infected polyp... truly fast and infectious. Please address it
immediately or risk the loss of other corals in the tank>
If I do save it, will it look healthy again. I have included a
picture for your review. I have a bubble coral, fox, brain, Alveopora, mushrooms,
and a feather duster.
Thanks !!!!
<best of luck. Anthony>
Bubble on Brain Coral - Polyp Bailout 10/5/03
Dear Anthony,
<howdy>
I have had this weird closed brain for 2 years and it has grown a great deal
creating the "brim" of what now looks like a Mexican hat.
<a handsome specimen indeed>
We discussed the bubbles that grow from it previously but I didn't have a
digital camera. The attached photo shows a bubble about 1 inch in diameter. I
can't find anything about this phenomena. It doesn't seem to harm the animal. It
is a sign of ill health? Or? -
Howard in Wisconsin
<it's called polyp bailout... and it usually is a stress induced response
(light shock, allelopathy from accumulating noxious elements in the water, etc).
It can occur as a natural reproductive strategy however. Perhaps the case here.
I describe polyp bailout a bit in my Book of Coral Propagation. No worries, my
friend. Anthony>
Pagoda with red stringy stuff 10/3/03
I have a large pagoda coral in my tank and it was doing fine. Now
it is not opening and out of some of the polyps there seems to be what I might
call red stringy stuff coming out.
<hmm... its hard for us to say without more information: depending on how
long you've had this coral (days/months?) and how long the polyps have been
retracted (days/weeks?)>
I have tried moving the coral to different parts of the tank but it has not
changed any.
<Yikes! please never move any coral respectively in one week... place it in
the tank one time (in a spot with light and water flow that you've researched)
and let it adapt. You can kill a healthy coral by moving it a few times in one
week at various different depths causing a burden on limited resources to
adapt>
All the other corals in the tank seem to be growing well. The tank
conditions are pH 8.2, Ammonia 0, Nitrite 0, Nitrate less than 5, calcium 400,
phosphate no trace, alkalinity is about 3.5meq/l, high but I don't know what to
do
with it.
<no biggies... all's well here>
It is a 85 gallon tank with a plenum system and seems to be
working well. Carbon is being used and I have two powerheads working.
<hmm... low water flow is a problem for pagoda (Turbinaria)... they need the
proper reef minimum of 10-20X turnover in the tank>
Can you help me with the pagoda problem and the high alk.
<for the high ALK... do test your source water first to determine where the
high ALK is coming from (or not). Its really not that big of a deal here>
The pagoda also has some white stuff coming off from around the edge. Thanks
Fran
<could be mucus from stress... do leave it in a place with very good random
turbulent water flow... and read more about water flow and Calcium and
alkalinity in our wetwebmedia.com archives (I have several articles there on
these topics myself). Best regards, Anthony>
SPS color changes - 10/3/03
Hi all,
Good morning! <HeeeeeeeLLO!> I purchased a tri-color Acropora a few weeks
ago <Nice one> and it turned a burnt orange or light brownish color all
over. <Well, this happens when SPS corals are either over or under
illuminated, stresses, or adjusting themselves to a new lighting regime and tank
conditions. Did you acclimate this coral? Start from the bottom of the tank and
move it a few inches each week? (5 days minimum before the next move) Do you
have the proper lighting for this coral? Where is it placed?> It
has been that way since day one, although at the LFS it was yellowish, pinkish
with green tips. <Sounds more like it. A beautiful specimen> It looks
dead, but I have been told they are only dead if they turn bleach white.
<Well not necessarily, but keep and maintain good water clarity with frequent
water changes to be sure> I am not sure what to do, if anything.
<Good water quality, depending on where you have it, leave it be> I have
tried moving it to different areas in the tank, no change. <Did you do this
frequently? Sounds like a very severely stressed coral (which also incites color
changes in coral.> Any suggestions or ideas? Will the colors come
back? <If not a dead coral for sure, then I guarantee with the proper
environment the colors will return> Thanks guys!

Candycane coral
Anthony, Gentlemen, or whoever takes this question of mine today, hope all
is well for you.
<Chris today, and same to you>
I have a candycane coral with about 15 heads on it, all with tissue, no
skeletons. I've had it for about 8 months, and I noticed the other
day that one of the heads lost its tissue and 2 others looked kind of like they
were on their way. The cluster of heads are packed tightly together,
but I think that is common for the candycanes. You guys have any idea why
this would happen?
<Overshading would be my first guess, or another coral's sweeping tentacles
are becoming within reach>
The whole colony has been doing great for a while, its tissue and tentacles
swell up at night to feed, and I do feed this corals heads fine minced seafood,
I'm kind of puzzled, everything in my tank is doing great, parameters all on
spec. That particular brand that lost the head has three heads
on it, with the other 2 heads looking kind of shriveled up as I mentioned,
should I saw that branch of the colony off ?
<I wouldn't worry unless the problem starts to spread. Keep an eye on
neighboring corals for sweeper tentacles. best, Chris>
Question About Ricordea - Allelopathy - 8/28/03
Hi guys
<howdy>
I read from books that soft corals engage in "chemical warfare" and
hence should not be kept in an aquarium along with hard corals. Can I check with
you if this applies to Ricordea which are not really soft corals.
<just wishful thinking <G>... allelopathy is conducted by practically
all cnidarians and plants/algae we keep in aquaria. The issue is not how to stop
it (impossible) but how to minimize it by keeping more natural mixes of corals.
Try to set up realistic biotopes and niche displays rather than the awful garden
reefs with a hodgepodge of everything but the kitchen sink (LPS, SPS, corallimorphs,
zooanthids, soft corals, hamsters, smurfs, etc).>
I will assume zooanthids and sea mats do conduct chemical warfare?
<they are fierce>
Many thanks in advance. Joey
<do check back next week on the "new at WWM" page for an article
I'll post on the subject. Best regards, Anthony>
Challenged corals /27/03
Hello, Thanks for sharing your knowledge. I have your new book
and can not wait for the 2nd and 3rd and .... in the series. Any
projected dates yet?
<thanks kindly... looks like 2004 for Reef Fishes... and 2005 for Cnidarians.
A one per year goal? <G>>
I have several probably unrelated questions. First I have a 2
year old 55 gallon tank with about 60 lbs of
live rock. Mainly Fiji LR. The questions are mainly
related to growths on the live rock.1st - One of the live rocks had a small
patch of a translucent yellow material. It almost looked like a
yellow colored silicon. It has spread to an adjacent rock and has
actually filled an approximately 1" gap between the two rocks. Is
this something to be concerned with?
<not likely... sounds like a colonial tunicate. Often appears or even feel
"rubbery". Else it could be sponge... a few look/feel this way>
2nd - I have a tube worm?? It is rust color and has formed a 1"
diameter coil on a piece of live rock. The end sticks out about
3/4" form the rock. If light hits it at night you can see
something move inside the tube. It emits a spider web like material.
<yes... a worm or Vermetid snail... feeding by mucus net>
I have seen my flame angel eat the web like material. A couple
of nights ago, the web like material stretched 7" to 8" inches and was
attached to my bubble coral. Again, is this something to be concerned
with.
<nope... good food/feeding>
3rd - A hitch hiker on the live rock looks like some sort of anemone. For
a year and half, it grew slowly. It is a magenta color and
is about 1" - 1 1/2" in diameter. It has what I will call a
trunk ( excuse my ignorance) that is about an 1 1/2" tall and is an off
white. The head of the anemone has feelers all the way around the
diameter and they are about 1 " long. At night the head pulls
into the trunk and it looks like a slightly oval shaped white ball. I
wasn't too worried until the last few weeks. It has
reproduced and there are know 4 or 5 of these anemones. I
know I am sounding redundant, but again - anything to worry
about?
<impossible to guess what kind of zoantharian you have here from the general
description. Do send a clear pic if possible>
4th - (Final question this time. ) I have a candy coral. And
again for the lack of a better term, I will describe it as several heads on
different stalks. Most of it looks very good. During the
day the heads are large and plump and are a beautiful lime green color. However
there is one stalk that has a head that looks like the skeleton structure is
showing through. There basically is no head (no green color and no
plump open coral) Can this be some thing that will damage
the rest of
the coral?
<possible if it becomes infectious>
Should I some how try and remove the exposed skeletal
structure?
<not yet if at all. This is a hardy coral... but can starve if not fed>
How is the best way to feed the candy coral. Most things I
read indicate that it does not feeding..
<holy cow! Quite the contrary for this very needy/hungry LPS coral. They need
over 20% of their daily carbon from sources other than light. Feed fine meaty
food of marine origin>
I feed Mysis shrimp, Nori algae, and formula 1 to the fish and I also
add some DT's plankton very sparingly.
<mysids, minced krill, Pacifica plankton would all be great. Easy on the DTs
unless you have a large refugium or many clams/gorgonians>
Sorry about so many unrelated questions. Thanks in
advance.
Tracy
<no worries... best regards. Anthony>
Galaxea - Aggressive Coral - 8/12/03
Hello to All!
Recently I purchased a Galaxea coral. It's a very beautiful coral and nice
addition to my reef. On the downside, it's tentacles are sweeping 4-5
inches reaching my xenia, which I have previously read about on your FAQs.
<the tentacles in time can extend to 10-12". This is a beautiful but
very aggressive coral indeed!>
I thought I had put him far enough away from all of my corals atop my live
rocks. Tonight, I realize that I thought wrong. I am now
dumb-founded on where i should place it. My tank is 65g, 85lbs LR
with 384w PC lighting.. With the tank being 24" deep, would I
offer him enough light to be placed on the substrate?
<PCs do not penetrate water adequately at depth (below 12-16" is weak
IMO). Perhaps position the coral on one of the flanking sides of the tank
(within 16" of surface) to minimize its battlefront>
Thanks Jason -Surfs Up!
<best regards, Anthony>
Does Blastomussa Pack A Punch?
Hi WWM Crew,
<Scott F. in today>
I received a Red Blastomussa ......Blastomussa wells is the species that was
listed on the invoice. I have enclosed a photo just in case they ID it
incorrectly.
<Well, I'm not a coral expert, but it looks to me to be Blastomussa merlot,
in terms of color. However, morphologically, it looks like B. wells...B. merlot
seems to have longer, individual corallites. I'll bet it is a variation of B.
wells...Geeze- how's that for help! LOL>
It was sent with an order, as an extra. I seem to remember a conversation I had
with a reefer friend who told me that they have very potent nematocysts and can
inflict a pretty nasty sting. I could of course be confusing it with something
else. I keep seahorses and worry about them because they will hitch to just
about anything and they can stay put for an incredibly long time. I avoid
anything that can sting and possibly injure them.
<They do feed, and, coming from deeper locations, prefer subdued lighting. I
have read about other sessile inverts growing within Blastomussa branches, so I
question the lethality of their "sweeping" capabilities>
Do you know anything about this species and it's stinging potential? If
not is there somewhere you could refer me. I have not been able to find a
resource that includes this sort of information about corals as it relates to
fish coming into close proximity.
<I have never heard about this species posing a threat to fishes. Which, of
course, is not to say that it doesn't! However, I will forward this to Anthony
for his feedback when he returns...He's forgotten more about coral than I'll
ever know!>
Any information is much appreciated. Thank you so much for your help! Leslie
<Our pleasure, Leslie...Regards, Scott F>
Mixing and Matching (LPS/SPS, etc...)
Hello Bob and crew,
<Scott F. your Crew member today!>
It's been quite a few months since my last question. Continuing along the same
line... I had a small (1") wartskin angler, Antennarius maculatus, in a 10
gallon tank that was plumbed into a 300+or- gal system. He shares the tank with
some Ricordea yuma. The main display is a 180 DSB with Acro frags on LR. Large
refugium and separate surge unit feed both displays which drain
to sump.
<Sounds like a nice setup!>
The boy has grown to about 1-1/2 and he is moving to a 40 gal plumbed into same
system. I would like to keep him with some LPS (Caulastrea, Trachyphyllia, etc)
but am worried about him getting tangled up in sweeper tentacles and the like
(heard about brains making a meal of errant hermit crabs). Is this a real
concern?
<Well, while in my heart of hearts I think it will be okay- I can't help but
suggest caution...The potential is there, even though it may be remote...Better
to err on the side of caution. I'd keep him away from corals like Elegance and
others that have the potential to consume fishes...>
Also, Scott Fellman did not think that allelopathy would be an issue between
Ricordea and Acros (separate tanks but shared water) but, as I understand, LPS
participate in a higher level of chem warfare. Should I proceed with the
additions of LPS? (I do run ozone and carbon in sump).
<Ahh- let me clarify for the sake of readers that may have missed it (and so
they don't get the wrong ideas about unnatural combinations of animals in reef
tanks! I have also seen plenty of great SPS tanks with Ricordea right there in
the tank, and there really haven't been any problems in long-term maintenance.
However, in every one of these cases, there was significant separation (i.e.;
physical distance and current flow) between the two, aggressive protein
skimming, and use of chemical filtration media. They are generally not found
together in nature, so it is certainly artificial to do this in captivity. I
don't like the idea of mixing SPS and softies, LPS, etc in the same tank.
However, it is done all the time...Does that make it right? Nope. Do I recommend
that everyone do this? Nope, but we are talking about captive systems here-so it
can be done if proper cautions are observed...As far as LPS are concerned, I
would be somewhat more hesitant, for the very reasons that you mention. Sweeper
tentacles and allelopathic interactions are a very real concern. These animals
are simply not found together in nature at all, and the potential problems
between SPS and LPS warrant this consideration. Of course, in separate tanks
with shared water, the danger is somewhat less, IMO. Your use of carbon, ozone,
and other chemical media increases the chance of success when combining corals
that are generally not found together in nature! If you understand the potential
problems, and how to overcome them, then proceed with caution!>
Once again, thanks for the time and service. I feel my successes are directly
attributed to the information and methods gleamed from WWM. Oh, clown boy thanks
you too.
<Glad to here that we've been of service! Good luck with your efforts!>
Oh hey, my LFS keeps bunches (2-3) of anglers together in a tank. I heard they
must be solitary. But they also have to find mates in the wild? Can they be kept
in angler communities or would I be paying for the most expensive feeders in the
land?
<Yep, you would! There is a very real likelihood that there will be "a
whole lotta munching going on!" In he wild, there is a lot more room for
them to spread out, and they will generally only interact when ready to seek a
mate...Definitely better to be safe than sorry here!>
Regards, Bryan
<Have fun, Bryan! Regards, Scott F>
Coral ID - Blastomussa wellsi - 7/7/03
I have a colony of some sort of coral growing on one of my mushroom rocks.
<It is the scleractinian (stony) coral: Blastomussa wellsi. Prefers
low to medium light like the mushroom corallimorphs of which you speak>
It is becoming larger and larger and I have noticed that it seems to have stung
the 2 mushrooms closest to it as they have retracted on the sides closest to the
unknown coral colony. The entire colony is about 1/2 inch wide with sweeper
tentacle length right in the 1 inch range. The sweeper tentacles are clear with
a white tip. I have attached 2 photos of the unidentified colony which seems to
be comprised of 6 or 7 animals. They have short tentacles around the edges
similar to that of polyps and a white colored ring around the centers of each
animal. I thought they were some sort of polyp until I noticed the numerous
sweeper tentacles so I am now leaning toward some type of hard coral. I was
wondering if you had any idea of what this colony is and if so is it worth
keeping or should I treat it as a nuisance animal such as Aiptasia?
<They are quite desirable... selling in most cities for about $40 for a full
colony.>
They kind of remind me of small Button Coral but I didn't think they grew in
colonies so I'm not sure what they are. For now i am preparing to move the
mushrooms out of reach of the tentacles until I have identified the colony in
question. If you have any ideas as to what this colony is let me know. Thanks!

Elegance Coral Question... And A Missing Page? 7/4/03
I have a large Elegance coral and have a question: this specimen has seven
'mouths'. How many am I supposed to 'feed'? Are they linked internally so that
feeding one (or every other one) benefits the others?
<First read up on the coral here... http://www.wetwebmedia.com/elegance.htm You
will see that if your tank is "properly set-up and maintained" you
don't have to feed your coral. Although many people do. It
too depends on the lighting you have above your tank... If you do end
up feeding it, allow the food to drift above all the mouths.>
Also, it looks like there's supposed to be an article on Feeding Corals by Bob
Fenner (Coral Feeding in Marine Aquarium Use). I get sort of a 'cover
page' with a tank photo, but no text comes up on my computer. . . was wondering
if this is a site glitch? The related FAQ's sections 1 and 2 come
through fine.<Probably not a glitch... just a page that is in the process of
being written. It should be up shortly I assume.>
Thanks in advance for your help on this.
<No problem, good luck with this beautiful yet hard to keep
coral. Happy 4th of July! Phil>
Hermit crabs picking at live coral
Hi, I really appreciate all the information I get from your site.
<Thank you for sharing your part today.>
I was searching on the necessity of hermit crabs and couldn't find an answer to
my
question hence this email. I traded in my 40 gallon tank for a 25
gallon
high because I move around at least 3 times a year and wanted something
easier and cheaper to maintain.
<Cheaper? Yes, Easier? Not sure about that one as the greater the volume in
a system, the greater the stability.>
I took my 30 blue legged hermit crabs in as well as all my fish except for
the two percula clowns and my fire shrimp. I have not had any success
in
keeping my corals alive until I got rid of the hermit crabs, they kept crawling
on and picking at them. I am maintaining a reef tank now and want to
add a lot
more corals.
<Be careful how you define 'a lot' as with fish, corals need room to grow and
feed
without having chemical warfare with each other. Do research the different types
of corals you are thinking about so you can avoid these problems and choose
tankmates that will co-exist with each other.>
My question is, am I required to have hermit crabs to control
the hair and other algae on the rocks?
<Certainly not. Water quality is number one in nuisance algae control.
Regular
weekly or twice weekly water changes will do wonders. Personally, I don't like
the hermits and lean more to a diverse combination of snails. Astrea, Cerith,
Trochus, Turbo and Nassarius> I don't think I should get another
tang because my tank is too small for one.
<Good call, you don't want fish that are much more than 3-4" when adult.
With
the 25 I don't think you want more than one more.>
What would you suggest?
<As per above, Don>
Please help!
Brackish corals and puffers
>How much coral do you have to put in a 10 gallon brackish tank with green
spotted puffers.
>>None.
>I never see coral in brackish tanks anywhere only in saltwater tanks. Do
they like a high ph or only saltwater puffers?
>>Corals like relatively high pH, and require so much for their growth
that I couldn't begin to address it here. If you're speaking of using
coral skeletons in a tank with marine puffers, then I would caution against it
as I have seen torn skin (they don't have scales. Marina
Coral Colors Redux
Hey Anthony- I know, I know, i said my last e-mail would be the last, but am
still confused on one issue. My protein skimmer has now taken care of
my organics problem which has resulted in my SPS corals getting less brown.
<we cannot say with certainty that your nutrient problem has been totally
"taken care of" by the skimmer... it has helped, but not likely
"solved". Excess nutrients are still likely tied up in bio-mass
elsewhere after months of growth>
You say its not "prudent/responsible" to say that a lack of UV is the
cause of lack of color in the SPS corals.
<correct>
What else could be causing it.
<good heaven's... thousands of pages have been writ on the subject and today
it is still unclear. Yet the reasons are many...>
I though that SPS corals are colorful due to their UV reflecting pigments
because they are at such shallow depths and sometimes even out of the water!!!
<true for shallow water species... but why then are some deep water species
heavily iridescent? (metallic Hydnophora, red and green Cynarina, pink/red
metallic open brains, etc). These corals are brightly colored with reflective
pigments to "refract" the weakly available light at depth within their
tissue (and not reflect UV away like shallow water species). If you give them
brighter light in aquaria... guess what happens? They shed those
pigments/proteins and become less colorful! My point is... you are looking for
one solution to a multifaceted problem (multiple species of coral from many
places on a reef and colored for many reasons).>
My first step will be to upgrade my reflectors which will move both sets of PC
actinics to the front.
<does sound like a good start>
From there, i will consider upgrading to 250's after a few weeks
to see any results.
<do archive some of Eric Borneman's online articles on coral coloration
too... and see if you can find some of Dana Riddles new reports if out yet>
Thanks!!! Josh P.S. Sorry to be a bother...
<no bother at all... best regards, Anthony>
Re: your website on coral mortality
Hi Bob
Thanks for your site - a job well done, very informative and I like the
presentation. Just for your info re: Parrotfishes - there are currently 89
recognized species (Bellwood, 1994) and most of those species that scrape or
excavate on coral reefs actually redistribute existing sediment, rather than
producing it (Bruggeman, 1995). If you need more info on these references I can
provide you with such. Also it is not necessary to say 'living coral polyps' as
all coral polyps are alive, although I agree that this small redundancy is not
so important.
<Ah, merci. Want/ed to state that many Parrotfish species scrape
"previously" live coral matrix as well.>
Hope you are getting the input you had hoped for when you put this site together
<More and more. Thank you again. Bob Fenner>

Mr. Calfo, Could you read my thread at ReefCentral and tell me if you think I
am way off base?
http://reefcentral.com/forums/showthread.php?s=&threadid=153669
Or if I have the right idea and just need to word thing better.
Thanks again Karl
<I think you definitely have the right idea Karl. Not sure about the open
statement though (purpose/intent/hopes to accomplish with a BB crowd). I would
also disagree that five years with coral is not a good indicator of success.
That number (at least with regards to allelopathy in a typical closed aquarium)
should be more like 1-3 years as unproven. Although 3+ years is not a full
lifespan... it is beyond placing the blame for many deaths on allelopathy in
large part. Good husbandry (or not) will make or break a tank by then... but
there are some lucky stiffs that get away in mixed/crowded tanks or systems
without water changes for a year or two. Still... I understand your point of
view and do agree with the premise. Best regards, Anthony>
Fish Bags - 2/13/03
Hello again, I am trying to find somewhere that I can buy bags from so I can
ship my corals in. I did a search on google and found polyethylene
bags (the pics of the bags on their sites look exactly the same as the bags you
find at fish stores) at a few sites and called to ask if they were the ones that
people use to ship fish and other critters in but was told that they probably
wouldn't be good for that. The guy said they would probably leak and
didn't sound like he worked there long. Can you tell me where I can
find quantities of bags that are made for shipping fish/corals. What
thickness in mils. do you recommend and how big of a bag? I figured
the polyethylene bags and the bags at the fish stores were one in the same. I am
sending a
link so hopefully you can tell me if these are the ones I need or
not. I, as usual, will appreciate any help you can
offer. You guys rock, Jeff
<these bags are too thin and will leak, Jeff. Freshwater fishes often get
bagged (or double-bagged) in 3mil plastics. Marines and spiny creatures go in 4
mil bags. 10x22" is a common size for this purpose. Double-bagging is
recommended for most. Close with rubber bands, never twist ties. And never more
than 1/3 water unless it is an air-sensitive species. Anthony>
Manipulating Coral Color
I have always had an issue with the color of my corals in my 72 gallon reef
tank.
<its a complex issue that cannot be resolved completely in any mixed reef
tank with unnatural collections (LPS, SPS, soft coral, mushrooms, etc)>
I have always had a problem with most of my corals end up turning
brownish/ tannish color( Although always healthy and growing).
<often a sign of high nitrates and/or low light (not necessarily from weak
lamps either... could be aged bulbs (over 10 months old), yellow water, dusty
salt creep lens/covers, etc)>
I was always told the lighting would effect the color of corals my coral the
most.
<depends on many factors... more is not always better, and sometimes it is
water clarity and color that is the issue skewing light penetration and coral
color... and not the lights themselves>>
So I changed it from 260watts blue actinics/whites to 440 watts of
03atinics/whites. The 03 made some impact but nearly what I was hoping for. My
tank holds mainly 90% soft corals, 2-tangs, 1 clown, 1 Firefish, 2- cleaner
shrimp and various serpent stars, snails and hermits.
<good to hear the focus on soft corals and not a hodgepodge. My advice for
optimum soft coral color is URI VHO fluorescent lamps or 150 watt 10K HQI MH
outfits>
The following were not supposed to be brownish but have slowly turned
brownish/tannish in color. The following was sold from GARF: Capnella was sold
as blue but now is tannish. POM POM Xenia were a brilliant pink but seems to
become more brownish in color the longer its in my tank( very similar in color
to the common Xenias). Lemnalia was sold as pink but has more of brownish hue.
Overall I have about 45 different frags from GARF.
<what?!?!? 45 frags in a 72 gall. I don't care how small they are, you will
be lucky to keep this mix alive let alone in good color for the allelopathy.
Wow... serious chemical exudations occurring here. The tank can look
"fine" and frags will grow for a year or maybe two. But I'd put any
kind of money on this tank having a serious problem in the 1.5-3 year picture
for it. Just too many specimens to grow out in one tank healthy>
All of these corals are doing well since 04/02 but I am very disappointed in my
colors. My mushrooms retain there colors. This gives my tank is very tannish
appearance from all the corals colors except I was wondering if it is
something that I am doing or if one of my levels is off.
<are you using carbon weekly or at least a large portion monthly? Are your
nitrates under 10ppm? etc>
All the normal test are within normal ranges.
<normal relative to what? Numbers would help here bud>
I follow GARF'S bullet proof reef recipe.
<heehee... bullet proof marketing too>
I use Seachem reef plus, reef complete, reef builder. I add Magnesium &
Iodine once a week. My PH is about 8.4. I also test for Phosphates, Calcium,
Alkalinity , Iodine and Magnesium. However my Iodine is always very low.
<Its taken out of solution within hours... I like dosing a small amount daily
instead of a large amount weekly>
Could this be my problem? Is there any other area I should be
testing that could be effecting the color of my corals?
<your coral are brown likely because they are over fertilized (phosphate
and/or nitrate)... Or... they have shed UV reflective proteins because they are
not getting enough UV (yellow water, poor skimming, dusty lenses or lamps, old
bulbs, etc). There are other possibilities but these are most common.

Coral Safe Fish Choices?
I am in the process of setting up a new saltwater system. I would like to
have a reef system, but fish come first.
<Very cool. I'm definitely a fish geek myself!>
I only plan on having 4 or 5, but they will be very nice fish. I am wondering if
the main two, Centropyge aurantia and Chaetodon tinkeri will leave any corals
alone?
<The C. aurantia is a great fish, but it may very well nip at some SPS and
LPS corals. The most difficult thing about these fish is to get quality
specimens (i.e; properly collected and eating). Many are collected with drugs,
do not acclimate well, and die after a brief period of time. The Chaetodon
tinkeri is definitely a potential threat to some corals, so you'll just have to
take your chances. Since these particular fishes both come from relatively deep
habitats, they should do well together. Once again, getting a good specimen is
very important to your success with these guys, so you'll want to get them from
a reliable dealer, such as Marine Center.>
What has a chance with those two? Thanks, Brandon Wilson.
<Really a tough call. There is no guarantee that the fish will not nip at
just about any types of corals...Perhaps some of the fine synthetic corals now
available will be your safest choice! Good luck! Scott F.>
Cladiella and Cabbage coral
Hi! I recently purchased two coral for my 75 gal reef tank. My tank has 440
watts of light and I have both soft & SPS corals in the tank.
<hmmm... OK. But not a good habit to mix soft coral and scleractinians in the
long run. Many allelopathic issues>
90% of my corals where purchased from GARF.
<OK>
I recently purchased two corals from my LFS. One was sold to me as a Cladiella
although I think it is Alcyonium because of the description in Eric Borneman's
book " Aquarium Corals".
<understood... and know that since Eric's book was published, all tropical
species in Alcyonium were moved out. The "Colt Coral" (Cladiella/Alcyonium)
is now (genus) Klyxum>
The reason I think this is because its color when purchased was dark/rich Pink
and almost closer to purple. The book indicates Cladiella come in colors that
range between gray - green - brownish.
<color should not be a primary indication of evaluating speciation>
Since purchasing it about 3 weeks ago - Its color slowly changed to a very light
pink. I don't think bleached out (still very healthy & still opens) but I
was wondering if it should exposed to much light.
<your lights are very fine... the coral is simply adapting to the change. Be
sure not to move it at all. All coral must simply be allowed to adapt even when
the first few days look weak>
All my other soft coral new & old have had no problem with the 440 watts of
light. I keep it at the bottom of my which is about 21 inches deep.
<actually, probably not enough light (at depth) under these fluorescents in
the long run. Fluorescent do not penetrate water very well at depth. After a few
weeks, move the coral up slowly to within 16" of surface at least>
Eric's book doesn't indicate how much this coral requires.
<this like most coral are collected over a wide range. There is no rule
possible for animals that may have been collected at 5 feet or fifty feet. Hence
the need for gentle and appropriate acclimation as you have done starting on the
bottom first (or using a screen method better yet)>
Will it do better if I were to put in a shady area like a mushroom?
<will surely die in time>
What is the lighting requirements for a Alcyonium? I am afraid it might die if I
put it in a completely shady area like under a cliff or under a over hang.
<corals are quite adaptable... and feeding can compensate for inadequate
light. Do consider a fishless refugium inline to produce natural plankton for
these corals>
The other coral I purchased was sold to as a (stony) cabbage coral. the closest
thing I found in Eric's book to it was a Merulina.
<Ughhh! A very delicate and difficult species>
When I purchased it it was a cream color. Is very white now.
<most bleach and die within 2-6 months of import/ For truly advanced reefs.
They need bright light and very strong water flow but cannot take the bright
light initially for the stress of import. Must be acclimated slowly to full reef
lights over several weeks>
I do believe this is a stony coral even though when I touch it - it feels very
rubbery.
<you are correct... it is stony (scleractinian)>
This coral I believe requires strong lighting. I recently moved it the center
and up about 3 inches from the bottom. Is there any you can suggest for both of
these coral- Thanks for your time- Anj
<you move of the <Merulina sounds fine. Please leave it be... moving
stressed corals can easily kill them for the need to keep adjusting to changes
in light. They have a better chance of acclimating to a new but alien light
rather than toggle between a normal and abnormal scheme. In my Book of Coral
Propagation I discuss several pertinent topics for you... summarized articles of
the same (coral feeding, lighting and acclimation) are all here on wetwebmedia
for free (better yet <G>!).It really sounds like you have done fine by
your new specimens but that they simply need to acclimate. With kind regards,
Anthony>
Re: Coral compatibility
Hi, crew...
<Good evening. David D. answering your questions.>
On my 75 gallon reef in recent months I've changed
out the chiller, exchanged VHO lights for MH, added a UV to
combat ich
<Quarantine is a better option but if you monitor the use of the UV it should
help with clarifying the water...if you use enough of it...but please don't
overdose...>
a canister filter to feed the UV...and now
the skimmer (had a small Berlin, bought a Remora Pro -
only to find it doesn't fit the canopy, so I've
changed it for an AquaC EV-120 in the sump). I've
also decided this weekend to reconstruct the insides
of the tank - I have way too much rock piled up in the
corners, the sides of the tank aren't even visible,
rock piled too high forcing some of the coral to be
too near the lights...I'm going to move some of the
rock to the sump, give more room inside the tank, and
get an external pump and plumb it so I can remove the
powerheads (I plan to move the coral to a separate
tank during the rearrangement, complete with
circulation). My remaining question as I put the
coral back is compatibility.
I have the following items of livestock: a (sickly)
pearl bubble, 2 regular bubbles (so-so), a Hydnophora
exesa (very healthy), a closed brain (Leptoria
phrygia, I believe), 3 open brains (Trach. geoffroyi)
(all very healthy), a horseshoe elegance (so-so), a
hammer coral (healthy), a frog spawn (healthy), a
Scolymia (healthy, I think), a leather (Sarc.)
(healthy), a pink leather finger (healthy), some blue
sponge (healthy), some green star polyps, some pink
star polyps, some button polyps (all healthy), and a
few assorted mushrooms. I also have a bulb anemone
that, until it started moving last night, had appeared
healthy, but now has moved to the top of the tank and
appears damaged near the tentacle base. I also have 2
clams (they've been very happy with the new lighting),
and plan to add a couple of Acropora (stags, mostly),
once I can get the water and placement sorted out.
With the reorganization this weekend, I have a unique
opportunity to rearrange where the corals that live within
the tank. Aside from the standard advice regarding
distance from lighting, etc. (which I've already
researched), I was wondering your opinion: I know
enough to isolate the bubbles several inches from
other coral (can they be near each other, though?),
same with the elegance, but aside from that, are there
any other dangers you see in this combination?
<The problem with the bubble and elegance is sweeper tentacles that will come
out at night. Both of these corals are notorious for stinging other corals to
death. In the ocean, this is how they gain a spot on the reef. The chances of
them stinging their own kind is less than the chance of them stinging other
corals but there are no guarantees...the corals didn't read the books! HA! Set
the tank up with softies separated as far away as possible from the stonies and
no coral should be closer than 6 inches from its nearest neighbor. I would give
even more space to the bubbles and elegance just to be on the safe side.>
I'm anxious to fire up the new skimmer this weekend to
improve water quality, but I'm wondering if some
combination I have is releasing toxins that are making
the bubbles reluctant to come out (both regular and
pearl). I had been blaming it on lighting, but I'm
starting to believe it's related more to water. It
usually is, I know...:)
<Run a full battery of tests starting with ammonia, nitrite, nitrate,
alkalinity, and calcium. See what the numbers look like. Keep in mind that your
lighting is a rather substantial upgrade and the corals most likely will be
somewhat shocked for a while. If there is a way to gradually increase the
lighting over a period of two to three weeks I would try it.>
Any advice would be greatly appreciated.
Arthur
<Sounds as if you've got a good thing going! Keep reading and learning! David

Coral ID
Hi, the live rock in question is cured Fiji rock. Both corals have some sort of stony base and the polyps are
only expanded (or inflated) in the daytime. They seem to engulf pieces of frozen brine shrimp and detract
quickly to the touch.
<it does not help much my friend.. there are thousands of possibilities. At best it sounds like a large polyped stony coral bud. Do know too that brine shrimp is a woefully hollow and inadequate food for most any animal. Its almost tragic that its still sold and popular! Do compare the single digit protein of brine shrimp to the 69%
protein of PE Mysis shrimp instead!!! So many better frozen foods (Gammarus, minced krill,
Pacifica plankton)>
I hope this helps as I cannot take a picture.
<do reference Eric Borneman's book Aquarium Corals for further help if possible... else continue to browse online for a photo ID. Best regards, Anthony>
Coral ID
Hi, I hope you can help me with a couple of
unidentified corals. After purchasing some pieces of
live rock and placing them in my tank I have
discovered two strange looking corals. One 3cm
diameter 'bunch' of purple bubble like things with one
tiny curl on each bubble pointing toward the centre.
And also what seems to be an anemone type (definitely
not Aiptasia) 1cm circular orange base with tiny white
tipped transparent tentacles (polyps?) which are about
2/3mm long poking out. Is it possible to have anemone
hitchhikers on live rock?.
<easily>
I have only 1 blue actinic bulb and 1 marine white fluorescent bulb. Will this
be sufficient for these creatures for the time being
(gathering funds for additional bulbs. Any help is greatly appreciated.
<we can't comment on the lighting before we know what the animals are and
what their respective needs are. To help you ID these creatures we need some
more information. A picture would be best (close-up). If not... we need to know
the type of rock (where collected) and some more details about the creatures. Do
either appear to have a stony base? Do they expand or contract at night? etc. Do
work on providing a picture, my friend... it will be easiest and most helpful.
Kindly, Anthony>
On-Line Coral Suppliers
Given your experience in the industry, I was wondering if you could supply
me with some names of on-line coral suppliers that have a very good reputation
and are known for shipping healthy specimens?
<You are best off seeking out the advice of other hobbyists who are actively
purchasing on-line for their impressions and feedback. Our message board is here
http://wetwebfotos.com/talk, there are others you may wish to check with.
ReefCentral.com and reefs.org are two big ones.>
Thank you, Angelo
