Shrinking Hammer Coral/Euphyllia Compatibility
Thanks so much for your dedication!
Thanks to you, my reef tank is thriving, minus one specimen: a
hammer coral. First of all, here is the tank information.
I've tried to include as much relevant data as possible for
an accurate diagnosis.
54 Gallon Corner Reef
Rena Xp3 Canister 350 gph (sump coming soon)
150 Watt 14K HQI
65 Watt PC 10K/6700K
2 Maxi-jet's w/Hydor Flo
RO water, pre-buffered
Tropic Marine Salt
2 gallons changed twice weekly
Temp 80-82.5 degrees F (running warm during the summer
pH 8.4 (p.m. reading)
Nitrate 0 (although undoubtedly present in tank)
Calcium 340 (running unusually low)
Magnesium- Still need to buy the darn test kit!
2 Bubble Corals
1 Candy Cane
1 Galaxy (isolated)
Green Star Polyps
Button Polyp/Yellow Colony Polyp (very small colony)
Fish and Inverts:
Lawnmower Blenny (small)
Small feather duster
Skunk Cleaner Shrimp
Misc. snails and tiny hermits
The tank was set up as a FO for 3 years and as a reef since
January. The hammer was one of the first specimens and over the
past 3 months it has exhibited obvious signs of polyp shrinkage.
The attached photo was taken 1 month ago and the coral has
decreased in size by about 20% (coral appears on the left side in
I have never witnessed any tank inhabitants sampling any corals
and do not think that allelopathy is the cause (you may
disagree!). I also do not think that the low calcium level would
be the cause. My best guess would be an issue with too little or
too much light or water flow. The specimen is placed about 18
inches under the HQI bulb and is fed a mixture of Mysis, NLS
pellet, and various blended marine meat (although it does not
appear to eat much compared to my voracious bubble corals). In
addition, I've noticed that it, along with my Frogspawn
almost completely withdraw their polyps at night and do NOT
accept food unlike the other corals. I attempt to feed these two
during the day.
My apologies for the long email. I do know that you prefer to
have too much info. as opposed to too little. Again, thank you SO
much for your generosity.
You truly have helped thousands of hobbyists and we appreciate
everything that you do!
<Your Torch, Hammer, and Frogspawn Corals are all Euphyllia
species and are aggressive in terms of allelopathy. The Hammer
Coral, in my experience, is the most difficult of the three to
maintain with all three being moderately difficult. I believe the
Hammer Coral is likely losing the allelopathy war. I would move
the Hammer Coral 6 to 8 inches away from the other Euphyllia
species you have in your system. A note on magnesium....magnesium
major element of sea water and should be maintained at
1200-1300ppm. Low magnesium levels hinders stony corals from
absorbing calcium to varying degrees depending on the actual
magnesium level in your system.
An example is if your calcium measures 400ppm and your magnesium
measures 650ppm, only 200ppm of calcium is actually available to
the corals. You may also want to read here and related
articles/FAQ's found in the header.

Torch Coral 5/31/2010
Hi gang, just back from Longboat Key Fla.
<Ahh! A few of us were t/here last year diving>
Had a great time and will post some pics later. Since I got back it
appears something has happened to my Torch Coral. It grew from 5 heads
to over 15 and was doing great. When I got back, 3 heads are dead and 3
or 4 are not expanding. The rest of the heads seem o.k. The only thing
I did different was to turn off the skimmer for the week I was gone.
Fish were fed every other day. There is a large Yellow Fin Damsel in
there and once in awhile he nips at it but nothing terrible. I
don't know if he would eat them?
<Might a little... if hungry... but sufficient to kill so much in
such a short period of time?>
or, if the water being "dirtier" had a negative effect. All
water parameters are good. The Frog Spawn is real good and all the
leathers are doing fine. Any ideas??

search tool on WWM w/ the term "compatibility" and read the

Frogspawn Tissue Recession... reading
I just finished reading Anthony Calfo's Reef Invertebrates
<... I'm the co-author>
for the first time -- a fantastic resource! But, unfortunately, I
haven't made it to his Coral Propagation book yet, so I was
hoping to get some insight from you all on some trouble I'm
having with my branching frogspawn.
<... have you read...? Obviously not, as you too have not
complied w/ our requirement of limiting file sizes for
It's been living happily in my tank for about 3 months with
no trouble until about three weeks ago, when I noticed that one
polyp had lost a single "section" of tentacle, exposing
the corresponding section of the skeleton (septum?) underneath. I
suspected that it may be from too much flow in my SPS-dominated
I continued to monitor this, but did not notice any worsening of
the condition until today, when I discovered that another
tentacle had disappeared (not directly adjacent, but 2 septa(?)
over from the first missing tentacle. Additionally, I noticed
today that the polyp that lost the tentacles also appears to have
lost some of the tissue and baring a white skeleton along that
branch, extending across a good part of the whole colony. I
don't know how long that's been that way. I've also
noticed recently that, while the colony still does
"inflate" (extending polyps/tentacles) a fair amount,
the average inflation size has been less over the past couple
weeks or so. it gets bigger than shown in the pictures I've
attached. I haven't noticed any brown jelly or slime from the
I have seen a few brown flatworms crawling on the frogspawn, but
than 5-6 at a time, and I've never seen any other flatworms
in the tank, so I haven't treated the tank to get rid of
<Not likely flatworms>
As far as the rest of my tank goes, none of my other livestock
any similar problems. The rest of my corals are SPS (Staghorn
Acropora, millepora, Montipora digitata, Montipora capricornis,
etc.), and my fish are: 1x bluespotted Jawfish,
<Misplaced here... won't live well or long... See WWM re
1x ocellaris clownfish and 1x royal gramma.
There is also a peppermint shrimp (I've seen them eat
Euphyllias in the past!), cleaner shrimp, and bumblebee, Trochus,
Nerite and Nassarius snails. The tank is 39 gallons
(24x20x20" cube) with a 12 gallon sump with a small Chaeto
refugium/5" DSB. My tank is lit by a 150w radium 20k halide
supplemented by 2x24w ATI Blue Plus actinic T5HO bulbs (I should
note that I have replaced each of these bulbs within the last 3
weeks, including moving to the 20k radium from a 14k bulb, but I
did take steps to acclimate the
corals to the new lights over about a week). For flow, I have a
Vortech mp10 (set to 100% reef crest mode) and Tunze 6025
powerhead, with a Tunze 1073.020 return pump. My skimmer is a

60lb of live rock in the tank.

Ammonia/nitrite are 0, and my nitrates/phosphates are
undetectable, but I do have a fair amount of hair algae, so I
suspect these parameters are not legitimately 0. My Ca is 420 and
my Alkalinity is 7 today (though it has swung between 6.5 and 8.5
over the past week -- I suspect this as a possible
issue here). I'm not sure what my Mg is, but based on the my
last test and subsequent dosing to correct it, I'd estimate
it is now between 1250 and 1350.
Is there anything I can do at this point? I'm usually not
someone who aggressively treats these sort of things, but based
on my research, I'm concerned that this may go downhill
quickly. My plan is to move it to a
lower-flow area of the tank. Is there anything else I should do?
I've attached some pictures.
Thanks in advance!

|Re: Frogspawn Tissue Recession
<Hey Josh! Just Bob please. I have no doctorate>
Apologies are owed on two fronts -- first, my apologies for the
large files. I had read the rules the last time I had submitted a
question, but admittedly, it had been some time, and I should have
reviewed them again before submitting this one. Second, I knew that
you were the co-author of the Reef Invertebrates book -- in fact,
it was reading the Conscientious Marine Aquarist book that led me
to read the Reef Invertebrates book in the first place. I think I
was just getting crossed-up based on the fact that Mr. Calfo is the
author of the Coral Propagation book. In any event, I just wanted
to apologize for my oversights.

Regarding my frogspawn issue, first, there does not appear to have
been any sort of coral competition that has led to this tissue
recession, so far as I am able to observe.
<Ahh, these events can be insidious in their moda>
I'm skimming and running Seachem matrix activated carbon.
Skimmer production has been steady, not unusual or elevated. The
frogspawn is well away from any other corals. It is situated at the
bottom of the tank, away from the direct light from the 20k halide
Regarding the flow, I positioned it so that it was far away from
direct flow from my powerheads, but it still seems to get strong
currents around it, frequently resulting in tentacles "bent
over" the side of its skeleton (such that it looks like the
tentacles may be in danger of being sawed off from the polyp by the

As far as the Caryophyllid FAQs on disease/pest/predation, I did
read through many of them yesterday before sending my email to you.
It was reading those that indicated to me that it could be an
Unfortunately, my reading of the FAQs did not indicate to me
whether this tissue recession was the type and extent that would
require a dip, or whether it might just be the result of the
fluctuations in alkalinity or predation (e.g. peppermint shrimp,
bumblebee snail), which would more easily be resolved by
maintaining stable water parameters/low stress and allowing it to
recover. Many of the FAQs with tissue recession similar to mine

length of time I've had it.

It was very helpful. The fish been "king of the sandbox"

now. Over the winter, the tank was staying at 78.5F pretty
consistently, so I wasn't as concerned; however, now that the
weather has begun to warm up, the tank is averaging up around
80-80.5F. I've just recently taken steps to try and cool the
aquarium with larger/more efficient fans/better ventilation. If
that doesn't work, I will be purchasing a chiller.

I know it's not what people expect to see when they hear
I'm not going to ask whats wrong as I'm quite sure I know
it was my own stupidity that cased the nitrogen cycle to crash
This was almost 4 weeks ago.
Once I understood what was wrong I did daily water changes of
about 20% of the water volume each day for 2 weeks and it has
saved everything in my aquarium except a few Montiporas and these
Euphyllias. Today I don't add anything except water and salt
and the water quality at the moment is:
temp = 26 C
salinity = 1.024
pH = 8.0
NO2 = 0.05
KH = 7.8
NO3 = 0
NH3/NH4+ = 0
MG = 1400
Ca = 450
The Euphyllia parancora doesn't show any tissue damage, no
brown jelly and the skeleton is not visible through the polyp
anywhere. It has just lost it's color and refuses to expand.
One week ago most of the heads had small bumps where the mouth is
and if anything moved the corals they opened the mouth and let
out some white "smoke"

Euphyllia when the nitrogen cycle crashed?

SV: Question about really sick Euphyllia
Thanks for the fast answer. The Euphyllias used to pick up a few
mysis or Artemia when I gave it to my fishes but as it is now
nothing will stick to the deflated tentacles and the mouth is
really hard closed.
<Please read the Caryophylliid Feeding FAQs files; where you
were referred last>
I haven't dosed any iodide as I thought the salt and the
frequent water changes would give me enough (I use Red sea coral
pro salt) but will start dosing tomorrow.
One thing I noticed since yesterday is that a few of the smallest
polyps seems to have inflated the tentacles a little. A few
millimeters closest to the mouth is now 2-3 mm thick instead of 1
mm as on the larger polyps.

bit of live tissue... BobF>

Frogspawn coral problems 8/24/09
<Hello Jessy here>
Just wanted to ask a question regarding my frogspawn coral.
I've had problems with ammonia from what could have been caused by
a bad batch of salt - everything seemed to cope except the frogspawn,
which was very sensitive.
It stopped eating shortly afterward, and although I changed brands of
salt, the ammonia dropped to zero straight after, it doesn't seem
to be able to recover properly. Still not eating and polyps on some of
the branches often shrink up or withdraw. Can this coral survive on
photosynthesis alone for long periods of time?
<This coral does not need to be fed at all. It can live very happily
without being fed directly, I've had frogspawn go from 3 heads to
50+ heads and never fed it once.>
I have noticed that although I have had no recession some of the
tentacles shrink up, turn bright green and start breaking off. I am
worried this could be harmful to other fish and corals should they eat
them by mistake.
<This is not harmful, its parts that are damaged from whatever water
quality issues you've been having most likely. Just make sure if
you see one landing on a surrounding coral you take a turkey baster and
blow it off. They will sting other corals.>
Also there is very high flow in the tank but my bubble coral is a very
happy coral -is this a factor in its recovery? All other corals in this
mixed tank doing very well - no problems at all.
<High flow shouldn't be a big issue if your bubble coral is
happy in the same tank.>
Water param.s are:
What can I do as I'm very worried about this coral?
<Looks like your parameters are okay. Just allow it some time to
recover and adjust to the change of salt. Don't try and force feed
it. It will be fine if your tank is healthy>
Also would like to know your impressions of Tropic Marine (thinking of
using) and Tetra Marine (recently switched to) and in your mind after
Seachem (not available here) what would you say is your preferred
<I've heard great things about Tropic Marine although I've
