Pool Shark
Five days ago, I bought two small Koi and two goldfish. I put the Koi in my 1000 gallon pond and the goldfish in my 30 gallon pond. Yesterday, one of the Koi and one of the goldfish died. Today, I lost the other goldfish, the other new Koi, and 2 of my older Koi (they were 6 inch Koi that I have had for about 2 months).
One of the larger Koi had a large chunk missing from its underside (see picture). All of the other dead fish, physically, looked to be okay. I tested the water in both ponds and everything looked good.
Today, all of my Koi appeared to be very lethargic. They are normally voracious eaters, they didn't seem to be interested in eating at all. I treated the pond with salt and also treated it TetraPond "Pond Fish Treatment". Tonight, the remaining Koi appear to be okay and were eating. Could this be a parasite problem?
I'd appreciate any input. The larger pond is only two weeks old.
