Goldfish Growth Question
I came across your website and was wondering if you could help me out
with a question. Sorry, I wasn't sure what email to use so sent it to
both the general and your own email.
I noticed some of my pond goldfish have developed some bumps on
I have come to the conclusion that they're carp pox as last year (in
winter) I noticed that the same fish had some ulcers on them so I
treated them with antibiotics,
<Mmm; not of much/any use here IF pox; which is virally mediated>
quarantined them and they all disappeared coming into summer. I didn't
notice that there were lumps last year, more so ulcers into the middle
of winter but I think I've caught onto it early this time.
The weather's getting colder again and we're going back into winter and
these bumps have developed even though the water parameters have stayed
fine/stable (currently at 0ppm Ammonia/Nitrites and Nitrates about
<Mmm; too high. See WWM re Nitrate control; keep under 20 ppm>
I will do a water change to clear the nitrates down, 30ppm General
hardness, 0ppm Carbonate Hardness and pH 6.5):
<No images attached>
I've read there's nothing you can do to treat them except just wait it
out, keep the water clean and support the fishes with a good diet.
<This is about it>
I'm thinking of getting a heater to bring the temperature up into the
summer temps to help boost their immune system and replicate the
environment that they went away in last year? What do you guys think?
<I wouldn't do this... for one, expensive to run/heat large volumes
outdoors; for two, the possibility of heater, electric failure w/
disastrous temp. fluctuation... and thirdly, better to let the seasons
gently cycle coming and going>
Do you agree that it's pox? They're still eating and behaving like
normal but I noticed that it's the exact same fishes that had the ulcers
last year in winter so it probably is viral/pox flaring up?
<Possibly... need well-resolved images to tell more. Might be
Furunculosis, or even just reaction to something/s adverse in the
environment. Do see/read on WWM Re:
and the linked (above) files in this series>
I would appreciate your help!

I'll do some reading. The images should be attached now.
<Ahh; they are... and this does look like Carp Pox to me...>
<You should look carefully into your pond conditions ("dirty water") and
do what you can to improve water quality, nutrition. There is no (other)
direct cure (as far as I know). Bob Fenner>
