Fish dying- fintail rot?

13 years ago

I am losing 2-3 fish a week and I have 2 currently acting lethargic with shredded tails.One is my favorite comet that I have had for 4 years. His tail has a big red streak that looks like blood on it.

I have not been able to catch them as the pond is wide and deep.

Here is a pic of the fin of one that died today.

His gill was deep purple-red.


Does this look like fin rot?

What can be used to treat a whole pond?

My pond is 15,000 gallons.

If not fin rot- what else may it be?

I am going out to test the pond water now.

Thanks in advance.
