Sick koi and need advice (with pics)

I have a koi with an unusual growth on its tail fin that looks like a
praying mantis egg sac. The fish also has hazy white areas on its
body. On its back there is a large opaque oval and I noticed some
smaller areas on its head. I first noticed issues with this fish in
the spring of 2005 and put it into a holding container with another
fish for several weeks as I dosed it with anti-bacterial and anti-
fungal medicines. It didn't seem to get better but upon closer look
it didn't seem like these white areas were disease, so I blew them off
as possibly an ugly batch of scales.

Now it's early 2007 and those white areas still exist and are possibly
larger but not substantially. The growth on the tail is something I
just noticed a few weeks ago and definitely is not healthy. I think
another of those growths exists on the underside of the fish near the
tail fin, but as you can imagine it's difficult to net and examine
this fish close up. The end of the fin itself seems to be diseased,
yet not in a way that would cause tearing.

If I had to take a guess I'd say this fish is at least 18" long and is
at least 2.5 years old and the other fish in the pond seem healthy.

Here are links to some photos:

The white region == http://s1974.home.comcast.net/sick_koi2.JPG

I have a feeling this isn't a bacterial infection, fungal disease, or
parasite because those issues should have spread to the other fish in
the 2 years that I've noticed odd health issues with this one. The
only other thing I can think of would be some sort of fish cancer, but
I'm not a vet so I have no clue.

Any ideas on what's going on? If so, what do I do about it?

Great shots! Pictures worth a 1000 words as they say. I'm thinking
Lymphocystis... more commonly called Carp Pox or it could be columaris....

They can be contagious, but not easily. Usually, if Carp Pox they get
better or go away when the season changes and the water warms up, only to
come back in the fall. Do a search on those things and then decide your
course of treatment. ~ jan

I have one with it, none of my others got it since 1999, so isnt too contagious. I
have seen carp in the Hudson river with huge carp pox around the mouth, very healthy
otherwise. Ingrid

My koi had it for years. None of the other fish caught it. The lesion was
removed along with 1/4" of healthy fin tissue before she went to the man
made stock pond. The other reason was all that catfish and trout chow had
her so healthy she laid thousands of eggs into mid-summer. This created
hundreds of unwanted fry overcrowding whatever pond or tank she was in.
They'd have to be drained down and the fry removed. A real PIA. I decided
with her excessive spawning and the pox.... she had to go.

I had a beautiful deep yellow female diamond-scale butterfly koi with this
disease. It looked exactly like what your fish has. She would appear cured
at times but it always came back. She went to a farm stock pond rather than
keep her with the other fish and possibly infect them.

Oh thats really good thinking there CArol. Push off yur sick or
diseased fish and put it in a farm pond out of sight out of mind and
let who ever has the farm pond worry about their fish coming down
with what ever the koi had if its communicable. At a minimum it should
have been euthanized and not dumped in another body of water, but
better yet, just like you told me, if you can not afford to take care
of your fish properly you should not have any..........you do
remember that statement don't you? Probably not, your suffering from
yet another bout of selective memory recall when things don't agree
with you. Yet your tract record of erroneous and bad advice predeeds
you as usual.

Looking at those pics my "Guess" is not worth a darn as I really d
not have a clue. None of my info from the university of Florida eveh
has anyhting like this listed, however its possible its an ulcer.
Short of finding a bona fide answer, I would dab it with some
potassium permanganate paste..Only do this one time, then apply some
panalog or other antibiotic ointment, and cover it with denture
powder. Yea sounds weird but if its an ulcer it will fix it. Let me
send the pics to a "fish doc" I know here locally and see what he
says.

Who cares what you think when you tell people to break the law and shoot and
kill protected water birds such as herons?

Great day, how did we go from koi herpes Virus to herons.your a bona
fide lunatic carol.......meltdown, meltdown, take action, lunatic on
the loose!


See, if we were on terms I would , show you my permit to harvest
herons , oh hell I ain't even gonna discuss it with you as it matters
not. What matters is finding an answer to this persons fish illness
and your beligerant belly acheing is not helping him any now is it. So
please go away and troll else where.

But I think yur totally off the wall tossing a highly contagious sick
fish into another persons pond and walking away from yur
responsibility, and possibly be the cause of a massive outbreak. YOu
got class CArol, real class, about as much class as the Nazi's did
during WWII . Your also a class act....and a fool!

Shooting at herons is legal in the UK providing that the gun is licenced
- I'm not sure if there is a need to get a special licence to shoot at
herons but from what I've heard from someone who keeps a fishery in
Scotland it does not appear to be....and the whole question of shooting
herons has no relevance to the OP question about his sick fish.

The dumping of Koi and Goldfish is illegal over here even if they are
healthy.....the dumping of a diseased fish is even worse IMNSO and
totally irresponsible...
