Welcome to the FishDoc case history files.
These are just a sample of everyday fish disease cases that I become
involved with. I guess most of us read plenty of books and magazines
about aquatic health and fish keeping and somehow the problems,
scenarios and often the clinical disease signs they describe never quite
match our own situation. It's almost as if everybody else suffers from
different problems to us, or our diseases are impossible to cure without
Fish disease is a complex subject
Part of the problem is that there is a tendency to oversimplify what
is after all a complex subject, dealing as it does with animal health,
water chemistry, biology, anatomy, animal physiology etc. Unfortunately,
a lot of very important stuff often gets lost in this oversimplification
and people often lose sight of the reasons why most diseases happen and
how to spot fish disease at an early stage.
This is partly due to lack of experience, but also encouraged by the
raft of myths and fallacies surrounding many aspects of fish keeping,
which often lead to fish keepers becoming total confused and bewildered
by all the conflicting advice they receive.
A big-time problem with resolving fish disease is the continuing
belief that you can diagnose fish disease by simply hearing a
description of the fish behaviour or physical change - or by a cursory
glance into the pond or tank. No matter what the experience of the
person concerned - at best this can only be a
guess and not a diagnosis. My own experience is these guesses
are very often wrong. If the guess is wrong, then it follows that
the treatment will be wrong and the losers will be the fish.
Fish disease case histories
So, to put a more practical spin on the subject I will be describing
and detailing a sample of cases that are relevant to a particular aspect
of fish health - be it water quality, disease diagnosis or treatment. In
the majority of cases you will see how problems could have been avoided.
I will, wherever possible include photos, but this isn't always
