In addition to Jan's request for info, you might also describe any behaviors
you have seen with the fish, that might indicate parasites, and if the vet
did a scrape and mentioned any parasites. Ulcers show up on fish that have
parasites, or are otherwise stressed. The water quality is one potential
stressor.

my pond is in Scotland UK and I have recently suffered problems with
ulcers.
lost 6 fish to date. I have tried the remedies available in pet shops to
no
avail. I have taken my large Koi to the vet to be injected with
antibiotics
but catching the smaller fish is almost impossible. Probably have 6 fish
still infected, varying from goldfish, shubunkins and comets. My pond is
well established 10+ years and this is the first fish that I have lost
for 5
years. Water quality is good. Best regards John

PS this is my first post ever on a newsgroup.

Hi John, and welcome to rec.ponds.

So what did the vet say was wrong with your fish?

Water quality is good, is not much to go on, could we have the numbers for
Ammonia, Nitrite, pH & KH, pond water temperature? Maybe we'll see
something you don't. ~ jan
