Another interesting thing about fungus (I've been told) is that it is
naturally occurring and rarely completely eradicated. I suppose that in
a closed environment like an aquarium, the species of fungus would be
static, so the fish would acclimate to them. Fungus is rarely a problem
to fish though (except for open wounds). I wonder if it isn't bacterial
in origin? Thanks for sharing.

I'd have to agree that this type of thing happens, although I feel that
quarantine would reduce the occurrences.

However, I don't believe that this is the only cause. I think there
are
probably quite a number of different causes.

One cause I have found that is closely related to the Netmax Theory
involves
fungus.

The fish I catch from the Moore River all bring some kind of fungus
with
them, although they are completely uninfected and totally healthy.

In the river, the flowing water must prevent the fungus from getting a
hold
on anything. However, in a small aquarium, the tiny traces that come
with
the fish eventually grow and cause real problems.

Everytime I add a new fish into the aquarium fresh from the river,
there
will be a fungal outbreak unless I dose it with something first.
