Re: Rescued Large Goldfish - very very ill - please advise urgently !!!

Update:

Good news !! (so far...  don't want to tempt fate)..  He is showing a
significant improvement.  He's not 100% yet by any means, but I'd say
he was around the 60% mark.  I was advised to give him 50% daily water
changes with 3 grams of salt per litre, plus half the recommended full
dose of anti-bacterial - administered daily rather than the full dose,
wait 4 days, second full dose advised on the bottle. The guy in the
aquarium shop said this would be better due to the large water changes
each day, which would dilute the medication too much.  Seeing as he is
showing some improvement, I've started to lower the temp slightly.  I
don't think 80 degrees is good, long term, for a goldfish - or am I
wrong ?

He also said not to feed him for a few days, but when I watched him
tonight, he was obviously 'picking' around the bottom looking for
food, and since I've had him (1 week now) he's eaten virtually
nothing.  Plus, I seriously doubt he had eaten anything for a while in
his old tank, as he was so ill and the tank was so filthy.  I couldn't
bear to see him hungry after not eating for so long, so, I went
against the advice and fed him some bloodworm.  He ate a few pieces -
the first time I've ever seen him eat, then ignored the rest - so I
removed it from the tank.  It was good to see him get some
nourishment.  I hope I've not hindered his recovery by feeding him too
early.  He is also moving a lot more, and his fins look much less
stiff than they did.

I think he's probably going to make it after all :-)

Now...  I have to get him a proper tank, as he can't stay in that
plastic 'tidy box' for long.

Unless there are any objections to posting small binaries here, I
would like to end this thread (once he's 100% and in a new tank) with
a small photo of the patient.

Thanks again to everyone who has helped.

Cheers for now,

Kev.
