There are many types of fungi and can be broken down more into different
categories. I'm just going to talk about the general fungus and that is
normally a white cottony looking stuff that will infect an open wound.
This again is a bacterial infection and needs immediate attention.
I'm not going to get into detail about this and there are people out
there that can explain this better than I. Dropsy is a bacterial
infection that infects the fish from the inside and you will see the
scales sticking out from the goldfish's body. Normally when you see this
stage of it the goldfish will most likely not live for much longer.Dropsy
The fishes eye is bulging out of the socket. This is normally the first
signs of Dropsy. You can stop it with meds. Popeye
A white stick like worm will be sticking out of the goldfish with a red
ring where it is attached. The fish normally will be rubbing against
anything to get rid of it.anchor
This is not a pretty thing to look at, once you see it on your fish you
will know what I mean. It's a greenish disk shape creature about 1/5 of
an inch wide and attaches itself to the goldfish. The goldfish will be
rubbing up against anything to get it off. You will also see red spots
where the fish louse was. There is ways of getting rid of them but you
must to it fast cause they do reproduce quickly. You can remove them
from the fish manualy, then treat the tank for the ones you dont see. Photo
This is not a Disease its a problem. Goldish with is problem have a
floating problem either they are sinkers or floaters. The Fancy
goldfish in general seem to have this problem. High levels of nitrates and bad water quality can cause this problem.
Excessive slime coat, isolation, clamped fins, scratching and flashing,
sores and ulcers as the result of the scratching. With gill flukes, it
is gasping at the surface, gills being irritated.
Small holes appear in the fish's body, usually in the head region. These
may gradually develop into tubular eruptions with cream-colored or
yellow strings of mucus trailing from them. Fish are lethargic, stop
eating and may develop a hollow-bellied appearance. Faeces may become
pale and stringy. Lesions may also develop at base of fins and along
lateral line, and fins and skin may also erode, body may become milky in
appearance and slime coat begins to come off in strands.
Gasping at the surface, slime patches around head and gills, sudden
death (especially in spring), small hemorrhages under chin, spider web
kind of lesions.
Irritated skin, flashing and scratching, which can lead to ulcers.
Flashing and scratching, thick slime coat, white-yellowish patches on
Cottony growth or white threads blowing out of mouth, lethargy, clamped
fins, thick heavy slime coat, dry skin.
Often a paling of the skin followed by black patches on body, usually on
back or sides of fish.

first began to show.)
