I was doing my regular water change on my 100+ gallon pond today and I was shocked to see a huge white spot on one of my original feeder fish, it's brown so the spot was clearly visible.
I can't have sick fish, so I am now draining the whole thing!
I have a couple juvinile Koi and 3 other little gold fish in there and I try to keep the pond well filtered. It is covered with a net and has a few water lettuce over the top so my local population of raccoons won't deplete my stock(happened once!)
NONE of the other fish have any thing wrong with them, they don't even have as much as a scale missing! I pulled all the fish out and the last one was the brown one that started it all...

This poor little guy is about 3.5" long (common feeder goldfish), and it has about a quarter sized hole just before the tail!!! flesh gone!, but no flesh eating bacteria, just a hole! It is also missing most of its lower jaw...Crap.
As I stated it is alive and swimming around normally, but it looks like crap! What should I do with it? euthanise? I mean it is swimming, but I'm not sure what caused it?!
Here's a pic...
Missing jaw
Oh and I just saw his buddy that I add at the same time, this other brown fish is about 3/4" bigger...Makes me wonder how long the other one has been like this?
Help please!
