Halofolliculina corallasia
7/27/15
Pretty sure I've got this little bugger in one of my coral frag tanks
(Halofolliculina corallasia). It has been taking out corals like crazy.
Checked it out under a microscope after dipping the corals (thinking it was
black bugs) to discover it didn't look like a crustacean at all but rather a
tube or poop. After reading this article I'm pretty confident in my diagnosis,
however can't find any information about what to do. As of right now we are just
disposing of dead corals using disposable gloves so that we don't spread it
around. Any thoughts?
Matt
<For browsers, the quick wiki:
https://en.wikipedia.org/wiki/Halofolliculina_corallasia
I'd be treating either the system or the moved/enroute corals with a quinine
compound to kill this Heterotrich. My first choice is Chloroquine (di)phosphate.
See WWM re dosages, protocols. Bob Fenner>

Thanks for the reply Bob. Searched for the dosages and protocols and didn't find
much re: corals other than CP is harmful and that corals should be removed when
treating fish. Also searched the web at large for using CP
on corals and didn't find much there either. I do have CP at my disposal in good
quantity and would love to start saving some corals. Perhaps you can provide
more guidance...
I'm presuming this is a dip scenario
Mg/liter?
<I'd stick with the same maximum as per system treatment 20 mg/l>
Duration of dip?
<Half an hour... with spg reduced a thousandth or two... Some folks might add a
good deal of iodide-ate and perhaps several mg/l of a hexose sugar>
Repeated dips required?
<Possibly; but not usually>
Will I be able to tell if the protozoa are dead after dip by looking at them
under the scope (They always appear dead to me)?
<You should... try adding a drop of household strength H202 to the cover slip
edge. Should move them if alive>
I've read multiple sources say it spreads through direct contact. Should I be
concerned about it traveling around on egg crate?
<Yes; anything wet is suspicious>
Are you aware of any natural predators, maybe a shrimp of some sort?
<I am not>

Just thought I'd follow up for other readers to confirm that this dip was
successful.
<Ahh! And thank you for your report/follow-up>
So far we are at about 6 weeks with no recurrence after a single dip done for
the most part as you suggested. 20mg/l in slightly reduced alkalinity <salinity?
really spg> with the addition of Lugol's solution. I skipped the sugar as I
didn't have any on hand and couldn't find any at the grocery store). We ended up
doing a longer length dip, after looking at the critter under the microscope
after half an hour (with a touch of alcohol also as you suggested) they were
quite wiggly. So we ended up doing closer to an hour, however, after looking at
them again under the microscope they were still quite wiggly so I think it was
actually just too much activity from the alcohol making them look alive. I'm
still not sure on that one.
There was one we had under the scope whose tube appeared to poop when we added
the drop of alcohol, not sure if that was one of the buggers dying or some other
microscope foible. Anyway, appreciate the solution,
Matt
<Again, appreciated. Bob Fenner>
Re: Halofolliculina corallasia 9/10/15
Haha. Yes... spg. Not alkalinity.
<Ahh. B>
Re: Halofolliculina corallasia

We had a discussion a while back about this nasty critter.
<I do recall>
I reported dips in Chloroquine Phosphate successful but that success was short
lived. We've been battling this like crazy with recurring dips which seem to
slow it down, but don't seem to kill it off. I'm guessing this has to do with
lifecycle but I can't find any information on lifecycle or life stages.
<Mmm; have you looked re "related" organisms? Other Heterotrich, Scuticociliatia
?
See these for input:
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2227702/
http://www.zoology.ubc.ca/courses/bio332/Lectures/Ciliates/ciliate_life_cycle.htm>
We've expanded our dipping to two hours just to increase exposure time.
I'm not sure the impact on the corals. I don't really see a difference between
doing it for 2 hours or 30 minutes in terms of coral health, as they always seem
to eventually succumb to the ciliate eventually. The ciliate most definitely
targets weaker corals, for example we dipped a large number of Montipora in
Potassium Permanganate which has been quite successful in the past for
eliminating Nudibranchs.
<A strong oxidizer... am wondering (so am writing) if concentrated H202 might
work, be less harsh>
It takes the Montipora several weeks to recover but they usually do. This last
time, only a small fraction recovered. The ones we lost were all covered in H.
corallasia. Removing the infected area helps to some degree.
I pulled a large number of infected corals out, chopped off infected areas,
dipped them in Chloroquine, then put them in quarantine for about a month. I
moved them to the main system and within a month they were all infected again
after apparently doing well in the quarantine.
Unfortunately there are so many variables I can't figure out what's working and
what's not. Do you have any other ideas or thoughts?
<Would soaking the CP in with foods the corals will take be another avenue?
Do you lower the spg (a few thousandths) in the dip water; AND add a hexose
sugar while doing the baths? I would. Bob Fenner>

Re: A prob. protozoan; your input please /Jake Adams

Halofolliculina is not a parasite in the classic sense. It seems to be
an opportunistic coral irritant that only grows on the edges of corals margins.
It seems to colonize only on slightly unhealthy corals. Instead of dipping like
crazy, I recommend cutting the healthy part of the frag and throwing out the
rest. Meanwhile, be more generous with your spectrum of trace element addition,
Iodine, Fluoride, Iron, Boron, Zinc, Molybdenum and Manganese to encourage more
robust tissue in the coral and much faster encrustation.
<Thanks Jake. BobF>
Location and a sick coral 1/1/04 Hello there, <Hi Eric,
Happy New Year!> I have been making use of the info on your site for
close to a year now and have found it to be very
helpful. I have 2 issues which I was hoping to
get your assistance with. <Glad you have found the site
useful. Lets see what we come up with....>
1. I know that corals are not supposed to touch one another,
however, I have a Sarcophyton that is now surrounded by mushrooms (due
to growth) some of which are in direct contact with the
Sarco's stalk. Everyone has been doing
fine for the past several months (all of the aforementioned
corals have been in the tank for at least 7 months -
touching for about 2). Should I move the Sarcophyton? <As a general
rule, corals should not touch, but if they have grown this way, and the
interaction isn't harming either coral, I would leave
it. Do watch both parties for any bad
reactions. Also... Either coral may look fine, but the
interaction may be causing a heightened chemical
response. Observe these and other corals in the tank for
other wise unexplainable poor health. Be prepared to move
one or the other if things decline.> 2. I had a mishap
with my Goniopora (a sponge fell on it and was there
for most of a day while I was at work). The
Goniopora now has what appears to be a brown slime
infection. I'm worried about doing a dip with
Lugol's. Would a freshwater dip be
advisable? Have you ever used a product called Ruby
Reef HydroPlex and if so what did you think of it? <I
have not used the Ruby Reef product, and am wary of any product that is
not clearly labeled with ingredients and a description of what it
does. Freshwater dips are usually as or more deadly to
corals than to infections. A proper Lugol's dip is
probably a good idea, but brown jelly usually proceeds so fast that by
the time you get this and do the dip, it may be too
late. Try 10 drops Lugol's per quart of aquarium water
for 15 minutes.> Thank you for your time and any answers that you
may provide. <hope this helps, and good luck! Adam>
Sincerely, Eric Baker
Elegance coral and regrowth 9/29/03 Hey
Guys!!! Let me start by saying THANK YOU for such a great
website and such great information. I think I can say for
all of us out here that your website is INVALUABLE!! I am
pretty new to this hobby, about 4 months, and I couldn't have
accomplished what I have without you guys. <thanks kindly... do
share your wisdom in kind> OK, Here's what I have for you
today. I have a Catalaphyllia jardinei (?sp?)
<Catalaphyllia jardinei> that my girlfriend bought me for a
present. Unfortunately it is starting to slowly waste
away. <if you've had it for more than a few weeks...
could be attrition. They need fed almost daily... at least several
times weekly with finely minced meaty foods> It is secreting a lot
of mucus and the brown jelly stuff. <ughh... a necrotic infection.
This like all new livestock should have been quarantined. The brown
jelly is highly contagious to other corals> Per your
website and everything else I have read, I put it in my hospital tank
and gave it an Iodide bath, Cause Iodine is toxic right?
<ahhh... used properly, it is anti-septic/medicinal so-to-speak>
I also supplement with SeaChem's Reef Plus, and Reef complete so it
is getting some Vitamin C also. I have read some people will
cycle antibiotics also. Is this worth a shot and if so,
which one or ones should I use? And is there anything I can
do to save my precious present? <tetracycline has been used in
bar-bottoms QT tanks with some success at mfg dose strength> Also,
if it starts to recover, will it regrow over the spaces where the
skeleton is showing through or not? I sure hope so. <it
can indeed in time> She is the one with the pink tentacles with the
purple tips. I had her at the bottom of my 40 gallon breeder
in lower light with low water flow also. I heard from your
website this is the best placement. <agreed... although
not too low of flow. 10X tank turnover is the minimum> Oh, she was
also placed on her back with tentacles toward the light
too. This is correct right? <correcto> My tank
parameters are: pH 8.5,sg 1.025, temp 79F, calcium 450, Nitrates 0,
Nitrites 0, and ammonia 0, phosphates .02. You guys have
taught me well!!! (I hope so
anyway! Hahahha!) <all good... although
the Calcium does not need to be that high... wane lower is Alk is
flat> I change 5% of the water twice a week also. I think
this really helps with my 40 gallon breeder. Agreed, my
friend> It's so easy and fast too!!!! Thanks for all
your help guys. I know you guys get this question a lot, but
everything that I read, and I read all of the responses and questions,
didn't really hit on my question. Thanks again
guys. Will be in touch. Oh yeah, I am attaching a picture so
you guys can see what your knowledge has helped me to create.
<thanks kindly... could not open the zip file though. Please send
pics as web-sized jpegs. Thanks kindly, Anthony>
Brown Jelly infection on Gonio I think that my Goni might
have brown jelly disease, there is a kind of orange film
developing on some of the polyps, how do I get rid of this infectious
disease and save my Gonio? <this secondary barrage of infectious
pathogens known as "Brown Jelly" is highly infectious and so
virulent that odds are not good at all of saving the specimen. You will
be lucky if it doesn't kill other corals in the tank too (healthy
established ones too!). This is just one of the many reasons why it is
so critical to quarantine all livestock for a full 4 weeks before
adding them to a display. Besides having a better chance to save the
new guy, there is always the risk of infecting some/all of the
established animals. My advice is to capture this coral underwater with
a large plastic bowl and lid (the coral is to be moved slowly and
sealed in the bowl underwater) to reduce the chance of drifting
infected tissue through the water. If any pieces do float away...
siphon them out promptly... it is highly infectious to other corals.
Treatments to date are highly experimental with antibiotics, FW dips
and iodine spikes. I honestly don't think the coral will be alive
48 hours from now, I hate to say, but do consult Eric Borneman's
Aquarium Corals book for an extensive range of options. My advice is a
60 second shower under cold tap water (seriously) before placing it in
QT. Maintain vigorous circulation and aeration in QT as well. Best
regards, Anthony>
Goniopora and brown jelly (protozoan) infection? Hey Anthony,
The good thing is that I don't have any other corals in my tank,
<a good thing> I was coaxed into buying this Goni as my first
coral by my local LFS. <wow... if they are receptive, willing to
learn... please suggest that they browse and use our free
resource/database for themselves and their customers. Promoting success
in the hobby is out mutual goal. Also suggest that they buy either of
Eric Borneman's coral books for a quick reference to not make such
a terrible mistake again> My coral doesn't have much brown jelly
on it and I am thinking that it might just be decay of the slowly dying
coral. <agreed... simply decay. "Brown Jelly" is wickedly
virulent... you can literally watch flesh fall away over a period of
hours.> Thanks for all the help involving my Goni. <best regards,
Anthony>
