Thanks for your reply McKoi
$$ How large is this pond? Is it filtered? Is there a lot of mulm on
the
bottom?
It's about 2,000 gallons, 3ft deep. Filtered with UV, fairly clear
water. Test results are all coming up good, PH, nitrites, etc. Well
stocked with oxygenating and cover plants. Stocked with 16 fish of
various types (Orfe, Red Goldfish, Shubunkins, Ghost Koi, Mirror Carp
and a couple of small Tench).
$$ Could it be the dreaded ulcer disease? Koi-Zyme and some antibiotic
food
should help - and very clean water.
It doesn't look like any pictures of ulcers I've seen anywhere, which
is why I wondered if it was new skin/scale growth or some form of
necrosis of the damaged tissue.
## Without seeing it it's impossible for anyone to say.
$$ Not if the pond was the problem in the first place.
All of the other fish in the pond are perfectly healthy, no signs of
disease, lively and feeding well.
## Then there just may be a problem with the few that have this
"infection." You can play the wait and watch game - see what develops
before starting to treat the whole pond.
We did have a problem a few weeks ago whereby, whilst we were out for
the day, the charming children at a birthday party next door decided it
would be fun to throw the remains of half eaten chicken skewers and a
few of their toys over the fence straight into our pond. The skewers
were found near the waterfall, where the fish like to play in the
running water. Needless to say, the fish were a bit timid for a while
after that. I'm pretty convinced that this was part of the problem,
leading to stress, possible injury and thereby the dreaded fungus.
## This is quite possible. But from what I read what's called fungus is
really a bacterial infection, You can hand treat it with Methiolate on a
Q-tip or diluted iodine. Gently go over the fungused areas a few times - at
least once a day. Don't let ammonia build up in the hospital tank.
I've subsequently treated with salts and am going to add some stress
coat today.
Any further suggestions will be appreciated.
## You can also ask this on the goldfish NG.
