Rainbowfish Mailing List Archive: RE: [RML] Mycobacteriosis article and one picture

I have to agree with Gary. :o =0D
I have seen aquarists be careful and fail time and again. Rainbows get
disease if they are stressed; and stress comes in all shapes and sizes.
If you were going to test every supplier of fish, you would probably
find FishTB in all of them, (assuming that you had a method of thorough
testing).

my 2 cents worth,

Hi Diane,
=0D
I took a quick look at the article and one thing I didn't seem to see,
not a zip squat natta on how often you change the water in your
rainbowfish tanks. One of the things that those of us that have kept
them over the years know that nitrates are a stress point for rainbows.
So are temperatures above 80 degrees, probably because of lower O2
levels. I'm sure that there are a lot of other things that we can't
measure in water quality that also stresses them. pH swings, which can
occur (I think I remember NC water being pretty soft and low KH
(buffering capacity) this causes stress on rainbowfish. WHEN they pick
up these stresses they tend to be susceptible to Myco. Without the
stresses and any character with open or active sores the problem
absolutely goes away. THe problem is that Myco is everywhere and it's
probably a silent carrier (just like Ich) which only pops up when there
is a major wrong happening in a tank. It's carried on plants, Corys and
any other fish you might think about putting in your aquarium. I really
don't have time for a full discussion about myco but if you want to keep
it from your aquarium then you need to perform LARGE water changes.
David B (TFH editor) has a great talk on why your water changes should
be 50% or larger. Math and tables but it makes it pretty easy to see
the reasons. People will go to some extreme methods to avoid performing
water changes and end up blaming their fish deaths, (not necessarily on
Myco) on strange and weird diseases. If they just bucked up and did the
required water changes (LIKE WHAT HAPPENS IN NATURE) then they wouldn't
have the problem. Lose the stresses lose the myco. (I've also heard
this from people at the public aquariums for other types of fish). The
rainbowfish can now resist the disease. It's taken me a long time to
come to this conclusion but I think I've probably been keeping bows
longer than most on this list and I also have the experience of keeping
many tanks of them. =0D

Dear Bow Lovers,
=0D
I posted finally finished and posted article on my experience
with=0D
Mycobacteriosis. =0D

I also posted a recent photo of my 55 gal, which contains
Yellow,=0D
Turquoise, Red, and a pair of M. trifasciata (Goyder River).
All are=0D
infected with Mycobacteria. It was killing the fish one-by-one,
but=0D
the dying has stopped since I added a UV sterilizer. More info
in the=0D
article.

Hope this helps!
