Now I'm really worried!
 

Oh dear,

Following on from the Sad Day thread:

I lost two of my SAE's and two more Neon Tetras suddenly this evening, just
when I thought everything was okay.

I didn't understand why after changing the water two days in a row (100%
changed in two days) and getting my chemistry right and back to stable
levels, why my fish were still passing away.

Some of you may remember I posted a while back about a Serpae Tetra female
that had what appeared to be an eaten away lower jaw due to "fungus"? (read
on because it's a major sign of what I now suspect is happening)

Well all of the Neons that have passed away have had this white-ish band
across their head from gill to gill.

The band appears seemingly over night, then they gasp at the surface, become
disorientated and then die. My SAE's that passed tonight had darker bands
from gill to gill and one of them was being chased literally to death by a
rampant Hockey Stick Tetra who just wouldn't leave it alone.

Considering that several factors have occurred of late in my tank, such as
high temperature (30 C), dirty substrate (only discovered this two days ago
and have vacuumed it clean each day since), low dissolved oxygen (a fairly
rapid raise in hardness and CO2 combined with the high temperature), stress
(trying to catch 5 BATs and disturbing one and all in the process - also
there has been some inter-species, and in-species (being bothered by mates)
spats) and a pretty big fluctuation in water quality, and slight over
feeding it seems, over the last 3 weeks or so;

I have come to the conclusion that what is now really killing my fish of
could very well be *Columnaris flexibacter*.

All the conditions have been there for it to develop and some of the dead
fish have shown mild external symptoms of it (the bands on the heads, the
dissolved lower jaw of the Serpae, and in the case of the bigger of the
SAE's that died - rapid respiration, lethargy and a complete change in
behavior several hours before and leading up to death).

The two Swords that died a few days ago showed no symptoms what-so-ever -
they just died very quickly, and they were both young and visibly very
healthy.

As Columnaris is gram-negative and contagious in warm de-oxygenated water, I
can state that I am *very worried* it's going to wipe the entire fish
population in my tank out.

The treatment I believe, and I need the more experienced people in the
groups to help me out here with this, is to lower the water temperature,
oxygenate, siphon gravel daily (it reportedly can grow on excess food and
waste on the gravel), change water daily and as a final resort dose with
Potassium Permanganate or Sulfur compounds? Does this sound right?

I have to act quickly on this or it's going to wipe the whole tank out, if
it is C.f..

I honestly can't see it being anything other than this because my water and
gravel are right on spec.

I am also guessing this is the price you pay too for not home quarantining
fish before they go into a tank? or are these bacteria always present in the
water column waiting for the right conditions?

If the worst happens and the entire population gets sick and dies, what is
the procedure for the tank itself?

Would you advise breaking the entire tank down, steralising everything
(especially filters and gravel), dosing the plants in Potassium
Permanganate/Bleach/H2O2 or something?

Oh boy, please help if you can - I think I am in big trouble and I'm about
to lose all of my fish :(

Many thanks in advance,

Oz

HI Oz,

A good old fall back that I always keep to hand is Malachite Green.

Try the site http://www.fishdoc.co.uk/ It's very good but always read
all the instructions as some things are not mixable or may need a drop
in temp etc. One thing that is often recommended but oft forgotten is
to turn off UV lighting.

Hope that's of some help.

Not experienced, even remotely, but just done some research....from what I
can see Potassium Permanganate is not the way to go - it can become more
toxic the higher the pH level. Have you considered using Melafix/Pimafix? I
also read that something containing Phenoxyethanol can help (don't know if
it is contained in Melafix/Pimafix) - apparently it can be found in some
proprietary medicines...Also read that an antibiotic such as oxytetracycline
might be needed

Apart from that it is water changes, gravel cleaning, trying to keep the
temp down and the water oxygenated as you say....

Flexibacter columnaris apparently is quite commonly present in aquarium
water, on dead organic matter and even on healthy fish skin....

Oz, I think it's our Aussie climate. I have not added new fish for over
a year and about 6 weeks ago developed the same sort of symptoms you
describe and I also put it down to Columnaris.

My tanks temps have been regularly over 27 and for quite some time were
over 30. I gravel vacc twice a week without fail. I have read over and
over that Columnaris is nearly always present in a tank and something
triggers it to blow out. I reckon the heat is a trigger.

I'm hoping to have something sorted out for cooling by next summer
although I doubt it will be for the same fish as I'm losing one a week.

I've learned that:
* Melafix and Pimafix are expensive and can lower the pH of your tank
dramatically. It only slows down the problem, doesn't cure it.
* Malachite green seems only available with formalin which can cause
major damage to your good bacteria
* UV sterilization seems complicated if you don't have the right filter
to push the water through the device to start with.
* I can't find a dose rate for potassium permanganate
* A water cooling system seems also comlicated and untidy (I am a female :)
* We don't seem to have access to antibiotics formulated for fish here
in Oz and if you buy them from the vet, apart from expense, it will be
in a form for some other animal and may have additives unsuitable for
fish ie. an injectable form of the drug that has some liquid to "carry"
the drug.

If you come up with any answers PLEASE tell me.

Good Luck!

Go to the University of Florida website and read for yourself on the
preferred treatment for columinaris (sp?) its potassium permanganate.
Thjis problem is perhaps the loargest problem any pond or fish keeper
or fish farmer is going to encounter in this part. And PP is the
approved preferred treatment in addition to antibiotic feeds.......

check it out at:
http://edis.ifas.ufl.edu

Look for the articles on:
Fungal Diseases of Fish (Fact Sheet VM97)
Use of PP to Control External Infections of Ornamental Fish (Fact
Sheet FA-37)
Columnaris Disease ( SRAC pub #479)
Potassium Permanganate in Fish Ponds (Fact Sheet FA-23)

Oh and nowhere doe sit mention any warnings as to Ph requirements, but
the use of MG does have warnings about PH as does other meds) Ph is
not much of a concern with PP)

Other than just visual signs have you scoped your fish to make a firm
diagnosis..........If your going by seat of the pants diagnosis, you
may well be in left field, but PP would still be applicable in most
all but say for Ick, where a copper of MG/F would be the best choice)

Hi,

I am in Australia and the ambient temperatures here are keeping my water up
at 28-30 degrees C, and there isn't a lot I can do to lower it.

I am going to commission a 50L plastic storage container as a Q/H tank
because I can cool 50L of water easier than 220L.

I'll go up to the LFS today and see what they have.

Thanks for your advice.

Oz

Excuse me for my ignorance if it shows but are your homes air
conditioned in Australia? In Canada, if the temp gets to 30C plus for
weeks on end most have air conditioners installed to keep it at
22-25C.

All the best,

Hi Gill,

I am off to the LFS today to ask their advice too. They probably have the
chemical resolutions but I know they don't carry medicated foods.

I read about MelaFix/PimaFix myself, on a few sites, but it seems it doesn't
really rid the tank of it. I went to AP's web site and checked out the FAQ
on these products and I like it that they are natural and don't affect
snail, plants or pH, and there is a small possibility I may be able to use
these two products, but there is some discussion around on the forum boards
(particularly Cichlid and Betta boards) that say it doesn't really fix the
problem.

I find this hard to believe personally, as I know what Melaluca (Tea Tree)
can do for human bacterial infections, and I have no reason to think it
won't do the same for fish.

Roy has stated that Flex is present always in everyone's tank, and
considering that fact, it makes sense that if a fish becomes stressed
through what-ever reason it's natural defense to it is going to break down.

I am shocked at how filthy my gravel was and I can't begin to stress how
important it is you get a really good gravel cleaner that suits your tank. I
was using a cleaner suitable for a small tank and when I bought the new 22"
one I'd say it sucked up 400% more junk on it's first use that the little
one just wasn't able to pull up out of the substrate.

Any way, I'll visit the LFS and I also am going to remove all of my plants
from their plastic pots full of clay kitty litter and replant them into the
substrate proper. I am suspicious that the clay in the litter is part of my
bacterial problem because I lifted a pot out a while ago and noticed at the
line where gravel and litter met there was a thin bright green band of what
looked like algae - I suspect now it isn't - it's probably bacterial.

I will wait a while to do this though unless it (Flex) gets so bad it gets
out of control. I don't think I should stress the fish if I can help it - I
need them to build up as much natural immunity/ability as possible right
now - there is war on! ;)

Regards,

Oz

I totally agree with you. My water has been at 29/30C for ages now and I
can't get it down for more than a few hours. This in itself is enough to
stress some weak fish IMO. I am in total agreement that temperature has more
than a passing contribution to this.

My tanks temps have been regularly over 27 and for quite some time were
over 30. I gravel vacc twice a week without fail. I have read over and
over that Columnaris is nearly always present in a tank and something
triggers it to blow out. I reckon the heat is a trigger.

I have had several of the other factors like dirty gravel, unstable water,
stress, sudden water quality shifts and low dissolved oxygen.

I am getting into a routine now of daily gravel vacuuming and generally
tidying the tank up and I think this is going to be the norm from now on if
I don't want to lose fish left right and centre for no apparent reason..

I'm hoping to have something sorted out for cooling by next summer
although I doubt it will be for the same fish as I'm losing one a week.

Sorry to hear that. It's terrible that it's so sudden and unexpected too.
One minute they are fine and the next they're dead!


I've learned that:
* Melafix and Pimafix are expensive and can lower the pH of your tank
dramatically. It only slows down the problem, doesn't cure it.

I am finding this out too by visiting discussion boards.

* Malachite green seems only available with formalin which can cause major
damage to your good bacteria

Shouldn't be an issue if I use it in a temporary hospital tank.

* UV sterilization seems complicated if you don't have the right filter to
push the water through the device to start with.

I can't begin to even think about this through lack of financial resources;)

* I can't find a dose rate for potassium permanganate

If I do, I'll post it for you. I am looking at this seriously and I can get
PP very easily.

* A water cooling system seems also comlicated and untidy (I am a female
:)
* We don't seem to have access to antibiotics formulated for fish here in
Oz and if you buy them from the vet, apart from expense, it will be in a
form for some other animal and may have additives unsuitable for fish ie.
an injectable form of the drug that has some liquid to "carry" the drug.

I wonder why we can't buy medicated food in this country?

I think it's time to really get the tank clean and keep it clean. That's the
first thing I should do.

And ultimately hope that summer passes, so we can all get our water down to
a reasonable temperature, but then at lower temps we get ich if we're not
careful - it's a minefield this aquarium thing! ;)


If you come up with any answers PLEASE tell me.

Don't worry I will ;)

Good Luck!

Thanks.

No, not all. It's quite common in Queensland and the Northern Territory, for
instance to use large ceiling fans. I myself use a fan.

Air conditioning is causing our state power grids to struggle and is
actually a big issue at the moment as to energy use. Power isn't cheap in
this country and most people on lower incomes can't afford either the power
or the air-con in the first place.

Personally, heat doesn't bother me - I like it and you learn if you come
from the the driest inhabited state on the planet (South Australia) as I do,
how to cool a house using naural methods. It involves "farming" cool air
from the night and trapping it in the house - un-airconditioned homes are
ususally the ones on a 40C day with all the windows and blinds shut - to
keep the solar radiation out and keep the cool air farmed from the night in.

It all seems strange to those who have air conditioners to level out their
cooling and heating, and I have been chuckling a bit lately because of a
program they show on TV here called "A Place In ....." where English couples
go looking for houses in Europe somewhere - they always whinge on about
central heating or air conditioning and won't buy a place if it doesn't have
one or the other or both :)
