Leather coral health, no useful info.
7/15/08
Hi guys, I am new to the hobby and have a good size leather coral in
my 140 gal tank. My leather is approx 6-8 inches wide when fully open.
He has always been rather healthy, but in the past two days he seems to
be not opening as wide as normal and seems to changed colors a bit. He
is normally a purple color with a strawberry like texture to him,
<? Really? I see a Lobophytum in your photo... Have never encountered a
member of this genus colored such>
but now he seems to have a marble look to him with a darker color and
white stripes. Any help would be good.
Thank you!
<... no other data? Read here: http://wetwebmedia.com/alcydisf12.htm
and the linked files above.... Need to know re set-up, foods/feeding,
maintenance/water quality tests, other livestock, recent activity... Bob

Re: Lobed Leather Coral Problem 7/18/08
Greetings,
<Salutations>
Still having a problem with a leather coral.?
<You are??>
It appears to be in the process of shedding, but there are several spots
of a yellow dried wax like substance.? The yellow substance comes off
easily when rubbed with a dull plastic tip.?
<Good... likely natural material... exudate... thought to be useful in
preventing fouling organism establishment and more>
No tissue necrosis underneath, but the tissue color appears different
than surrounding tissue.? Coral has been closed up for about a week
now.? It is not showing any tissue degeneration, but does slough off
some mucous on different? spots every night.? Lastly, I have notice some
very small flat worm looking organisms on the coral after lights out.?
<Might be... flatworms>
I siphoned them off, but can't tell if any damage was done.? Some small
shrimp looking animals have also been seen after lights out crawling
around on the coral.? What should I do from here??
<Mmm, keep on, keeping on...>
How long should it take for the coral to shed??
<Usually hours to days...>
Is a week unlikely?? Two weeks?
Thanks,
Greg

Lobed Leather Coral Problem
7/12/08
Hello,
<Greg>
I recently purchased a rose colored
<? Have never seen such in the wild...>
leather coral for a reef aquarium. Other inhabitants at the time were an open
brain coral, some platypoa (sp?)
<Maybe Palythoa>
polyps, pipe organ, and a mushroom rock. Everything was going great for weeks.
All corals were healthy and opening fully, including the leather.? I then added
one other mushroom rock and a single large hairy mushroom.
<Oh oh...>
The leather still had plenty of room to open and not be touched by any other
coral. I left for vacation a few days later and returned today. I have now
noticed some yellow spots on the rose leather coral, with one spot turning into
a yellow ring with darker tissue inside the ring. There is also a blotch of pale
yellow on one area of the coral. I am assuming this is some type of necrosis.
Am I dealing with some type of chemical warfare or may it be a water quality
problem.
<Likely the first, perhaps some of the second>
All other corals are acting fine. Tank parameters are:
pH: 8.4
Salinity: 1.024
Temp: 80 F
Ammonia:?0
Nitrite: 0
Nitrate:?0
I did notice that there was a power failure while I was gone, but I don't know
for how long. Also, the pH seems to have been unusually stable while I was
gone.? Usually it drifts down to 8.1 - 8.2 over several days and I buffer it
back up to 8.3 - 8.4.?
<Mmm, through water changes, gradually I hope, trust>
However, after leaving for a week, the pH stayed right at 8.4.? This hasn't
happen before.? I did change some activated carbon and cleaned out the skimmer
cup before leaving on vacation.? Should I leave it alone and see what happens or
take some action.
Thanks,
Greg

Soft Coral Rotting – 05/13/08
Hi there.
<<Hello>>
Was hoping you guys can help and quick!
<<Let’s see>>
I got what I believe is a medusa soft coral about 6-8 weeks ago and was doing
fantastic, but now is looking really worse for wear.
<<Hmmm, hard for me to tell without the polyps extended…but it looks more like a
Sinularia species rather than a Sphaerella species, to me. Not that it likely
has any bearing on your problem>>
I have tried to include some pictures to help but not sure how clear they will
be.
<<Clear enough I think>>
He has slowly refused to open more and more and for only very short periods when
he does. My other soft coral has also gone through a bit of a rough patch and I
thought it may have been down to a water change. I added my pH buffer to the new
water and it went cloudy, this took a long time to disperse and seems to when
they both closed down, could this have been the problem?
<<Ah yes, sounds like you had a precipitation event from over-dosing the
buffer…is very hard on your tank inhabitants. Do have a read here
(http://www.wetwebmedia.com/calcalkmar.htm) and also perform a Google search on
our site re “precipitation event”>>
My other one has now recovered to almost full health. What do I need to do??
<<Not much to do at this point other than maintain your water quality and ensure
your bio-minerals are in “balance” (reference the article)>>
Any thoughts or suggestions will be of great help.
<<The precipitation event was likely the “last straw” so to speak for this
coral. It was probably already in a weakened state from its close proximity to
that Anemone I see in your tank. Judging from the pictures, the tank seems “just
big enough” for the Anemone alone…and certainly too small to be housing it with
sessile inverts too…in my opinion>>
Most appreciated
Wayne Tunnah
<<Happy to share. EricR>>

Re: Soft Coral Rotting – 05/14/08
Thanks a lot for your help.
<<Welcome, mate>>
This has been of great use.
<<Ah…good>>
Perhaps I'll try moving him further away from the Anemone?
<<Won’t make much difference I think…not in this size tank>>
Or should I just sit on my hands for now?
<<Best to move the coral to another tank altogether>>
I've also made the water a bit more brisk around him to also try and help any
recovery he might make.
<<The increased water movement, though not likely to “cure” anything in this
instance…is still of benefit to the tank as a whole>>
The Anemone was only half the size in the dealers display and looked almost
fully open at the stage of purchase. He just inflated massive when I gave him
his new home! Guess he's happier now then?
<<Mmm, maybe…or maybe trying to gain more light from an insufficient source by
making itself larger/increasing its surface area…is only a guess>>
Thanks again and I'll let you know whether he pulls through or not.....
Wayne
<<Please do… EricR>>

Nitrite
spike... Allelopathy twixt Cnid.s 4/25/08
Hi,
<Ho!>
I have a 54 Gallon corner reef aquarium with sump filtration, aqua c
remora skimmer, 2 Koralia # 2's, 50 lbs LR, 25 Lbs LS, 130 Watts of PC
lighting. Livestock includes 2 false Percs, 1 royal Gramma, 1 Firefish,
and 1 banner cardinal. Small clean up crew 4 Nassarius snails, 4 blue
leg hermits, 4 red leg hermits, and 3 emerald crabs. I have 2 discoma
colonies that came on LR, and recently purchased a small hairy mushroom
colony and a toadstool leather.
<... get... very large>
The levels were Ammonia-0, Nitrite-0, Nitrate-2ppm, phosphate-.03, Sp.
G. 1.0253, Ph. 8.06, Calcium 420, dKH 3.15 mg/l. For about 10 days the
toadstool was looking fine as was everything else. Yesterday, it began
to slump over and retract its polyps (picture included).
<Yes... I see it being burned by the Corallimorph in the foreground...>
I couldn't determine if this is normal leather behavior or if something
was wrong.
<Mmm, in too small a world, too close to a better-established
Cnidarian...>
However, today the leather looked worse. I performed a water change and
performed water testing. To my surprise my Nitrites were up to .25.
<Yes... reaction from the life t/here>
I haven't ever had nitrites in the tank. Could the leather's problems be
contributing to nitrite spike?
<Yes>
Or is it doing poorly because of nitrites. I haven't really changed
anything else in the system and can't figure out what would cause
increased nitrites. Any thoughts/links, etc. would be helpful.
Thanks,
Mike
<Please read here: http://wetwebmedia.com/cnidcompppt.htm
for background, then onto the Compatibility FAQs files for both groups
of Cnidarians... Your options will be obvious. Bob Fenner>
Re: nitrite spike... Allelopathy
twixt Cnid.s 4/26/08
Thanks, Bob. Relocated toadstool to a QT that was up and running.
The plan is to get this guy in shape and return to LFS. It seems like it
was a bad choice for my system. That's what happens when you listen to
LFS and don't do your research. Lesson learned...
Mike
