Hello all, I have a 15x18 pond and have had 8 very large goldfish(8-10") in
it for 2 years now. I just put in my first koi. It has been in the pond for
2 weeks and still is a very active swimmer and feeder. All of the golfish
are fine except for one silver, red, and black one that has a white fuzzy
spot on its side.

This sounds like a fungus. I would isolate this fish immediately in a medical
tank and treat the tank with Maracyn (Erythromycn), according to instructions.
And just to be sure that it isn't a paracite like ick, I'd put some coppersafe
in the water, and in the pond as well (unless you have valuable invertebrates in
your pond).


The new koi has a red sore on its side and redness where
the tailfin meets the body. I really don't want to lose this one.
It is and white and black butterfly koi with and orange snout. It

Any sugestions on what is wrong and how to correct it would be sincerely
appreciated.

Randy


It sounds like the Koi has a bacterial infection. You should isolate this fish
immediately as well in an isolation tank and treat the tank with Maracyn II
(Minocycline) according to instructions. A rule of thumb when adding fish to an
extablished pond: Always quarantine them before putting them in ther pond to
see if they have any diseases. That way you won't be introducing infectious
diseases to the pond (which is usually hard and expensive to treat because of
the size). You do have an isolation tank, don't you? I have 1 fifty gallon
tuperware tub, and 1 twenty gallon tuperware tub that I use for treatment
purposes. It is important that the water is aerated during treatment, and I
always place them out of the weather, in a shaded area. If you can bring them
inside in a temperature controlled environment, it always helps. It also helps
to keep track of water conditions during treatment. Finally, when treating fin
and body sores, I always add some stress coat with aloe to the water, because it
helps soothe the sores, and helps the healing process.
