just looking for some help with one of my koi, 2 weeks ago it developed a white cloudy looking thing on one fin, we tried to catch him to get a closer look but it was impossible. he dissappeard for a few days but we spotted it again today and with a bit of team work cornered him and got him out the pond. he's in a quarantine tank for now while we figure our next move. also spotted the white cloudy mould on his nose...currently treating with esha200 and esha exit. any ideas? no other fish have symptoms in the pond. i have 3 photos but keeping getting an error message if i try to upload them here...

Hello, 
I'm very sorry to hear your koi is not doing well. Unfortunately, it will be very difficult to correctly diagnose the issue without an image (are you able to upload the images to another site such as photobucket?), but it sounds like the symptoms of a fungal infection. Before recommending any treatment, we will need some additional information to get a better understanding of the situation. Please answer all of the following questions:
How many gallons is the pond?
What are the approximate dimensions of the pond?
How many koi?
How often are you doing water changes, and how much water are you removing?
Any source of filtration?
What size tank is the hospital?
Water changes/filtration on this tank?
Do you have any way to test the water for ammonia, nitrites and nitrates?
The first course of action, especially with goldfish and koi, is to insure water quality is pristine. This can only be achieved with water changes. 50% water changes daily on the tank, and a big flush of the pond will help boost the fish's immune system, helping them fight off infection. Be sure you treat the replacement water with a quality dechlorinator like Seachem Prime to remove toxins in the water.
Please keep us updated, and don't hesitate to ask any additional questions you may have.
