Cynarina
question... hlth. 1/8/08
Dear Crew,
<Trina>
I have had the following Cynarina for about 8 months now. For the last 6
months or so, it has had this bubble that has gotten bigger over time.
It got knocked over once or twice by some out of control crabs but that
was months ago. Would the fall cause this "Tumor" and can anything be
done to help it out?
Thanks,
Trina
<I don't know what this is... but would try to excise it (with a sharp,
single-blade instrument) outside the system. Bob Fenner>
Re: Cynarina
question, hlth. 1/16/08
Thank you for your help. I did as you suggested and cut the excess
tissue away. The Cynarina took the procedure remarkably well and
expanded shortly after adding back to the tank. The tissue has appeared
to heal, or at least be in the process, but it looks as if it is
expanding again. Seems as if I am going to have to schedule the coral
for biweekly surgeries!!!! Any other options?

<Mmm, daubing the area with Lugol's, other iodide/ate solution post

Scolymia - Septa tissue damage 2/24/06
Crew,
<Jason>
Thank you for providing all this great information and I will try and be both
detailed and brief! I have recently purchased a Scolymia - red button
which I am having some problems with. First my parameters: 50 gal system, CPR
Bak-pak skimmer, CPR 24" Refuquarium, activated carbon running in a small
power filter, T5 lighting 1 Daylight and 1 Daylight/Actinic combo on a 12hr
timer. Water is great with 0 nitrates, 0 ammonia, 0 nitrites, PH 8.1,
calcium is 400. My salinity is 1.025. Additionally I have 45lbs of live rock,
and 3" of live sand. I do small weekly water changes of 5 gallons. I have 1
hairy mushroom, 1 small button polyp, 1 large button polyp, and a 1 week old
Scolymia. I also have a Maroon clown pair, 1 three stripe damsel, and a dwarf
flame
angel. Lots of snails, and some blue leg hermits. I use mysids, zoo-plankton,
pellets, Nori, DT's, Cyclops-eeze, with periodic Selcon soak in a daily
rotation. I try for a good diet variety applied lightly. My tank is 7 months
old, cycled fishless for 3 months. I purchased this new addition 1 week ago at a
live
fish store. The creature had been at the store for several months and I drip
acclimated it for 2 hrs after a temperature float. I did not add the creature
to my tank before testing the shipping water and matching salinity... but I
think I missed something or did a step wrong. I placed the Scolymia mid level
and
in moderate water flow with lots of room around it.
<All sounds good/fine thus far>
The night of the addition the Scolymia became mucousy... probably a form of
shock and some of its septa pierced the flesh.
<Very common with just-moved mussids>
Over the next week it looked better day by day, no mucus and the pierced tissue
seemed to be recovering. Today and yesterday it look
significantly better and was inflating its polyp/flesh. This evening however I
arrived home to find that all of the septa had pierced the flesh of
its mantle and the tissue had de-inflated. I have read in the archives that a
few septa poking through isn't uncommon (shipping transport damage) and can
probably
heal. What I didn't find was the likelihood of recovery with so much of its
skeleton showing and tissue damage. An additional problem is that the first
two septa that broke through have an algae film on them... possibly limiting its
ability to heal?
<The algae are indeed a bad sign>
My feeling is that this was probably caused by me during acclimation (its
killing me trying to figure out what I did wrong), different salinity's LFS at
1.021 then acclimated to 1.025.
<! Very different... would be a good idea for you to use a quarantine/treatment
system and slowly (a 0.001 per few days) move this animal between these
differences>
As I have only had this previously healthy creature for a week it doesn't seem
likely that its food or lighting. Nothing has changed in the tank since it
arrived one week ago.
So... can this creature heal with so much tissue damage? And will the algae film
on septa be a cause for concern?
<Yes and yes>
Thanks so much for such a great site!!

<I encourage you to add Iodine... likely as Lugol's solution here, and increase
circulation, aeration around this colony. Bob Fenner>
Blastomussa wellsi Troubles 2/18/06
Hello. I (as the title says) am having some troubles with a Blasto Wellsi I
recently purchased. I bought it about a week ago and placed it in the bottom of
the tank in low flow and low light. For the first few days, it opened fully and
looked great. But then on about the third day, it didn't open completely. Day by
day, it's been opening less and less. I wouldn't be worried so much about it,
but this is the exact say way my last Blasto Wellsi colony died last fall. I was
never able to figure out then why it died and finally decided it was probably
caused by something that happened before I bought it. Now I'm not so sure. I
have since lifted it up on to a small piece of pvc in the corner to keep it away
from the hermit crabs (they have a knack for annoying new corals sometimes).
<In addition to hermits, do consider your fish, especially pygmy and dwarf
angels and blennies. You may have to observe very carefully to notice them
picking at the coral. Also, in my experience, these corals are very sensitive
to water quality especially those parameters that can't be measured, like the
noxious defensive chemicals of other corals.>
The lighting is two 96W PC 12 hours a day on a 45 gallon tank. It's been set up
for about a year now. As for water conditions, they're fine (78 degrees; S.G.
1.025; 0 Ammonia, Nitrite, Nitrate, Phosphate; Calcium 430) as they have always
been, and no other corals (including many zoos and shrooms, a few LPS and SPS,
and some rather large softies) are showing any signs of trouble.
<What about alkalinity? Without proper alkalinity, calcium is unusable to
corals. Also, Zoanthids, mushrooms and softies are all good candidates to
produce harmful allelopathic chemicals that my be harming the Blastomussa.>
Nothing has been done since I received the coral that would change water clarity
(water changes, cover glass cleaning, new bulbs, carbon, etc.). I think that's
all the info I can offer. Thank you, Kevin
<You can try running some carbon to help reduce the defensive chemicals from the
other corals and please do measure alkalinity regularly and correct if
low. Hope this helps. Best regards. AdamC.>
Coral Healing & Book, V2
Date: Fri, 13 May 2005
Bob and Anthony:
I thought you might find this picture interesting. It shows both the
damage
that Aiptasia can cause and the power of a coral to heal. This
Blastomussa
achieved this amount of healing within 4 weeks of me killing the
Aiptasia
that made the hole. I used 3 ml.s of vinegar injected with a 20-gauge
needle.
Also, Zo is vacationing in Utah. I happened to be home last weekend, so
we
got together for lunch on Sunday. It was great to meet him and we had a
pleasant and interesting conversation. That and a recent WWM query led
me to
wonder how the second book is coming. Any projections on publication?

inexorably slowly. B> |

Candy Cane Coral 3/8/04
Hi Bob,
<Anthony Calfo in his stead>
Thanks for the help with the candy cane coral so far. I have
searched the web and the FAQs for... too long. I am meeting
with a man tomorrow about purchasing a candy cane coral. I
noticed that the color is usually a brown or a green. I am
concerned when I met with this guy that I will not know whether it is
healthy or not. Could you please give me some pointers as to
color, and basic appearance so that I get a healthy specimen.
<it's tough to summarize in the brevity of an e-mail. Obvious factors
to look for would be any recession of tissue, exposed corallum
("skeleton"), excessive mucus. But before you buy any coral
without knowing how to assess health, please, please, please invest in a
good book or two. John Tullock, Eric Borneman and, if I may say so, my
works on corals are easy to read, popular and informative. For corals with
pictures... I can recommend Eric B's "Aquarium Corals" as your
first choice. Please make the responsible choice and do not buy any animal
without knowing how to care for it first. Caulastrea (candy cane coral) is
fairly hardy and easy to keep, but requires feeding weekly or more often,
and will not acclimate easily to very bright halide light>
Thank you very much, Todd Hawman
I should have included a picture of what was posted on the net by the
seller. http://www.buysell.com/bestoffer/viewoffer.asp?id=26121043
this is the address to the picture he provides....not sure if it is
actually his. Please help!!
<the picture/coral is odd... appears to be healthy, but the polyps have
an inflated look. May simply be a photo soon after a feeding>
Also if this is a healthy coral... should I start
acclimation (in terms of lighting) very near the bottom on
rock?? I have a 90 gallon tank... 24" deep and have a 4
foot 32 watt fluorescent light. Thank you very much. Todd
Hawman
<keep this coral in the top 1/3 of your tank. Fluorescent lights may be
good quality but they are weak (unable to penetrate water at depth). I do
have an article here on WWM specifically on "acclimating symbiotic
reef invertebrates" to new lights. Do seek it (use the google search
tool at the bottom of the index/home page). Best of luck, Anthony> |

Maze Brain Coral
Hi I have what I think is a maze brain coral I've had for a few weeks that seems
happy in my one month old tank opens at night closes during day apart from
opening some parts every now and then in daylight. It originally had some small
crustacean things living in holes in it which didn't bother it at all but they
died recently either due to low pH (7.5) or high spec grav (1.029) which I have
now fixed, or lack of whatever they eat in the ocean and one of the vacant areas
now has what looks like a spider web over it with a funnel area the creatures
were removed as they died. What could this be, will it harm my coral and should
I do anything about it? << I tend to leave things in for two reasons. One is
laziness, as I just let my tank grow as it may. The second is because I like to
see natural tanks be.... well... natural. I like letting them take their course
and balance themselves out. >>I use natural sea water from the area my
inhabitants come from. << That is convenient. >> And what, how often should I
feed my coral? << Good question. Those corals can be directly fed, and I would
recommend doing so once every couple of weeks. >>I know nothing and live in the
country where there is very little information or product available to me. << I
wouldn't worry yet, but just keep watching it. If the coral tissue starts to
recede, then I would suggest fragging what remains. If it stays the same or
starts to grow, then I wouldn't stress it with fragging for a while.>>

Saving Lobophyllia (not Silverman) 10/3/04
I hope all is well with you today.
<and with hope for you in kind>
I do need some help in saving my Lobophyllia. My flame angel was nipping at it
continuously and causing it to recede to not much more than a skeleton. Since I
have a 180g tank with much
live rock, catching the flame angel was nearly impossible until I recently moved
and had to drain the tank. Since that time the Lobophyllia has expanded from
about 2.5” in diameter to over 7”!
Just when I thought all was perfect (for over a month), now my purple tang has
apparently grown to love the taste of the Lobophyllia.
<heehee...>
The coral has once again deflated to a little more than a skeleton. I really
like the purple tang and prefer to leave it in the tank (not to mention I do not
plan to drain 180 gallons of water again!). Is there anything that can be done
to stop the tang from nipping at the Lobophyllia and to keep the both healthy in
the same tank? --Greg
<nothing at all... really, short of separation. Its a compatibility problem that
cannot be conquered by extra feedings, etc. Do consider placing the coral in a
small inline refugium instead - perhaps the best of both worlds. Anthony>
Lobophyllia tissue recession 3/31/05
Hello, I have a Lobophyllia spp. For 2 months and never has been very healthy, firstly started with a small body reduction in the upper part (it was inclined in the aquarium) so I moved it down. But 2 weeks ago it started to have a severe body depletion, I have read different articles about corals, bleaching etc and I would like to know if I should move it down a bit more or any other tip. Thanks very much.
<"Tissue recession" is the most common term for this. Bleaching refers to the loss of Zooxanthellae (symbiotic algae) and color from otherwise normal healthy tissue.
Lobophyllia is quite adaptable to different lighting conditions, but in my experience it is quite sensitive to water quality and the defensive chemicals produced by other corals. I would suggest thoroughly testing your water and making sure the following
parameters are in the proper range: pH 8.0-8.4, Alkalinity 2.75-4.0 mEq (9-12 dKH), Salinity 1.025, Calcium 350-450, temp 79-82. If you have soft corals (especially leathers or mushrooms), it would be a good idea to run small amounts of carbon and change it weekly and perform 20% monthly water changes. Best Regards!

Cynarina looks sad
Bob
I enjoyed hearing you at the MARS meeting and watching your slide show a few months back in Sacramento. I wanted to ask you about a Cynarina, I think his common name is a button coral, I purchased in July. He seems to be slowly shrinking. He still fills up and expands but not as big as he used to.
<Why do you think this is so?>
I have him placed near the top of the aquarium with MH and power compacts. Not a lot of water movement there. My water tests are good. Calcium at 455 Dkh 9 and 0 ammonia, nitrite and nitrate.
I was told he only needs light.
<You know there is more to this>
But then I read they do put out feeder tentacles to trap food. I have never seen this. I only feed the tank frozen brine shrimp and flake food for the fish. The only other corals are a Colt and Green Star Polyps. Is his problem food related and should I be feeding the tank something additionally for the corals?
<Yes>
I also read he is a low light coral so I thought about moving him but I didn't want to make matters worse either. Any suggestions would be appreciated
Thanks
Jim Uptegrove
<Do look about more... and try other foods/feeding moda... these are "planktivorous" species to a large/r degree. Bob Fenner>
Problem with Lobophyllia
Dear Bob,
As always, thanks so much for this great site. I have another question that
I'm sure you can answer.
<I will try>
Last Tuesday, I received my order of a Lobophyllia hemprichii (red brain
coral) and a Euphyllia glabrescens (torch coral) from a dealer that is well
known and, supposedly, very well respected in the trade. When I removed
the torch coral from its bag, I could see nothing but the white skeleton and
a few places where the polyps were supposed to extend. After two days of
waiting, as instructed by the dealer, the polyps never came out and they
just became shriveled and died. That must have been RTN.
<Maybe>
As for the brain, it has not died, but I am very concerned about it. When I
first received it, I placed it in the bottom of my 90-gallon tank and even
shaded it from the VHO lighting for some time. The coral opened some during
the day, but when it retracted, a large part of the skeleton was exposed.
In fact, the "spines" show when the coral is contracted.
<This happens with new specimens>
According to our research, the coral should be of such a size that no part
of the skeleton should ever show and that the whole coral should look more
robust. The coral we received looks so "thin". When it's expanded, there
are pinpoint places that are depressed; and the flesh looks "corroded". The
color is rust red now; it may have been darker and lost some of it's color,
but that is hard to determine.
At times, the coral would expand when the main aquarium pump was turned off,
while at other times it would expand when the pump was turned on. The coral
gives off this rust-colored cloud when the pumps are turned off. This
morning it looked better; however, when I turned off the main pump it
retracted and gave off its rust-colored matter.
The dealer says in their literature that this coral would "slough off" some
when first introduced, but it seems to be sloughing off its flesh and
deteriorating.
The aquarium is a 90-gallon reef with all parameters at or near perfect reef
readings. We have a 30-gallon sump, Turboflotor skimmer, Aqua UV
sterilizer, and a water turnover rate of about 10 times per hour. Other
inhabitants look great. There is not a heavy bio-load as there is just a
purple tang, a peppermint shrimp, some mushrooms, a purple blade, some
snails, and a few scarlet hermit crabs, and three sand sifting starfish.
All water is purified by Kold Steril.
I added vitamin C and some trace elements (Vital Gold) by Thiel, along with
Coral Vital by Marc Weiss.
Any thoughts?
Thanks for any help you can give.
Regards,
Michael Rivera
<Per the descriptions of both newly arrived specimens, it does seem like they were either "in the bag" too long, or suffered some other sort of shipping insult (chilled, overheated... delayed in transit...). At any length, you can just wait at this point and hope that they will regenerate. Nothing in your description points to a difficulty in your system or handling... Bob

Bubbles in my Brain!!! (air trapped in coral tissue)
4/19/03
ok.. I attached a photo, but this morning is the first time I've seen
this occur on my Lobophyllia.. it looks almost as if there are air bubbles
inside the flesh of the brain coral..
<there are several possible reasons for this not entirely uncommon occurrence. In the safest/simplest circumstance... some corals simply
"eat" air bubbles (or are fed it trapped in food). As strange as
it might sounds... the deliberate ingestion is done by some of the more
heavily mucous species for the purpose of capturing food and elements such
as proteins that are attracted to the air bubbles (Yes... indeed like the
organics "stuck" to air bubbles in protein skimmers). In these
cases though... the tiny air bubbles are easily purged. When they are
large and apparent as in your case here... it leads me to believe one of
two things... forced ingestion of an inappropriate food (freeze dried
foods for example... that have much air trapped inside)... or stress. The
former is self-explanatory... and the coral is likely to expel it in time,
although you don't want to make that a habit! In the case of a stress
induced symptom here... there are a few things it could be... and neither
are good. The first is over stimulation (over-driving/photoinhibition) of
corals by light that is too much or on too long (for this species if only
in the tank). New bulbs, cleaned lamps, improved water clarity (carbon
used after an absence), etc... all are things that improve or increase the
quality of light and cause the zooxanthellae to work overtime to the
extent that they produce oxygen inside Cnidarian tissue that cannot be
processed fast enough. The other possibility is supersaturation of the
water with oxygen by a leak in the plumbing (causing the aspiration of air
to super-sat-levels)... OR... the inappropriate addition of hot water to
cool water (during a water change or evap top off) to make
"warm" water which drives the O2 out of solution quickly (the
reverse of super-saturation). This can occur right within the corals
tissue just like divers that get the "bends" from nitrogen. Not
good at any rate.>
it's been fine up until now and the only thing that is changed is that I
fed it chunks of krill last night before I went to
bed.
<no worries unless the krill was freeze dried or any food that floats
that world indicate trapped air>
is this something I should worry about? or take caution of?
<perhaps... do consider the above possibilities and why it may have occurred>
another thing I was wondering was that I have a large toadstool leather
that stopped opening during the day... I've noticed polyp extension at
night about an hour after the lights go off, but other than that it fully
expands during the day.. just that there's no polyp extension.
<interesting... generally not a big deal (they do not feed organismally
with their tiny polyps by much. However... in light of the Lobo's
symptoms... the polyps shutting down early does indicate a possible
lighting problem. Are you one of those kooks using 400 watt halides on a
20 gallon aquarium <G>? Perhaps have your lights on too long (over
8-10 hours on MH... or over 12-14 on fluorescents). Perhaps changed to
brand new bulbs recently? Hmmmm... many possibilities here.>
I'd really appreciate any information. Jonathan
<best regards, Anthony> |

Air Bubbles in Coral Tissues ("Bubbles in my Brain") 4/19/03
thanks for the response.. it makes sense on the light stimulation... he had
just been recently moved to a higher point in the tank.. but has since been
moved into another tank in which his air bubble situation returned to normal..
<ahhh, yes... very plausible and consistent with our theory. Great to hear
that your brain is not so gassy <G>. FWIW... corals that express such
symptoms (air bubbles from excess light as with sudden move to higher point) can
in fact acclimate to the new higher position in time... they just need to be
acclimated slower to prevent the air bubbles from forming. Use the screen method
(suggested in my articles here on WWM and beyond) to adjust the coral to
brighter light over a period of a couple weeks>
and I almost forgot to add.. I LOVE your coral propagation book..
the wealth of information is priceless and I've been looking for a book exactly
like this for years. Jonathan
<thanks kindly, my friend! Best of luck to you in your endeavors. Anthony>
-Scolymia showing teeth!-
Dear Bob, <Kevin here in his stead> I have had a Scolymia for about 2
months. It feeds nicely -almost every other day on bits of lancefish nicely
soaked in Selcon and Zoë. Originally it didn't have any 'toothy' extensions or
they were all entirely covered by the flesh. I have noticed that now
one or two protrude. <Likely from some sort of light damage> It inflates
nicely and eats avidly, if slowly -about 25 minutes- what I provide. <That's
a good sign> It is in good light, slight water motion and no nasty neighbors
that would sting. I was a bit worried that the toothy extensions through the
flesh my signal some kind of unhappiness or decay. <The toothy extensions are
it's septa which have pierced the flesh somehow, likely from some sort of light
trauma. If it does not become infected at the spot where the flesh has torn, it
should heal nicely. The only problem with the septa sticking out is the
possibility for an encroaching algae to develop and push the tissue back
further. Keep an eye out for this.> I like it very much and it is a coral now
no longer imported in the UK <Really?! Why is this?> so I am especially
keen to see it do well. Am I worrying too much? or is there something wrong?
Thanks for all the help on your fab site. <Good luck! -Kevin>

Unhappy Symphyllia 12/31/03
I purchased a beautiful Symphyllia about a week and a half ago and it is not
happy in my system.
<it really does not look bad in the pic... just irritated as evidenced by the
issue of defensive filaments>
It is mounted somewhat vertically in the bottom of my tank (75 gallon with 260
watts PC lighting).
<the lighting is not worry here... Symphyllia are adaptable to lower light
and require heavy (almost daily) feedings regardless of lighting (they are not
sustained adequately by photosynthesis)>
There is some white recession on the top edge and the bottom of the coral has
exuded it's digestive system in what appears to be small round tan
bumps. I have enclosed a pic that was taken after a Lugol's
dip. The little strings that are in the pic appeared after the dip
but are now gone.
<ahhh... no worries then. The recession may simply have been due to
mishandling prior to your purchase. It simply needs time to heal. Do not move
this coral around (or any.. very stressful). Put it in a good place and simply
let it adjust for some weeks. Keep it at a safe distance from other corals too
to allow for growth>
It does not extend it's feeding tentacles at night and has not eaten since I got
it. I've had it in 3 different locations in the tank and this makes
no difference.
<yikes! this is a surefire way to stress if not kill a coral. No wonder its
not eating either. The movement drains significant biological energies>
I have read that it can be sensitive to Xenia and I do have some in the
tank.
<I seriously doubt that. In fact... I'm nearly sure of it. Xeniids are one of
the most weakly noxious/aggressive of all soft corals.>
It is approximately a foot away from it. The only corals in close
proximity are a fox coral, red open brain and cup.
<"close" needs to be defined here... but I'll say at least 10"
distance needs to be between corals minimum... and further for aggressive
species>
I'm really worried about it dying on me. All of my other corals are
doing great.....it's the first coral I've bought that is not.
<more patience are needed here mate>
Other corals are Anthelia (about 2 feet away) some mushroom anemones (about 2
feet away), and a frogspawn (about 8 inches away).
<the frogspawn is a serious and present threat... way too close for this
extremely aggressive coral (they do not need to touch... noxious exudations>
I have an Emperor 280, Emperor 400 and a Remora Pro skimmer on the
tank. Calcium is running 400, alk 10.2, nitrates are 2, no ammonia or
nitrites. I have changed the cartridges in the filters so there is
fresh carbon running. What else can I do to help this beautiful
coral? Thanks for you time in answering...... Janey
<give it time and do have a long term plan for the tank. DO not overstock and
please allow room for growth, assuming you hope this unnatural mix of corals
will live long term for you. Best of luck, Anthony>
