You did correct in putting the fish into another tank to treat it.
Antibiotics will kill the bacteria in a comunity tank, bringing havoc.

Water pollution is the main concern for disease in fish. It brings about
everything into them. You did right in putting the fish out and with new
water, but this can also bring stress to the fish. Due to the many
conditions of this fish I will advise inmediate care with medications,

1. tail rot : can be bacterial or fungal, bacterial is just ragged fins,
fungal ragged fins and a white line around the edge, recommended treatment:
TC capsules for the first or Fungus cure for the last, both if it has both
and its not uncommon to see both at the same time.
2. gill disease : bacterial : fish are seen gasping and very red gills,
parasitic in addition to the above very small white gill worms can be seen,
if its bacterial NALA gram or EM tablets or Furan 2, parasitic I believe
there is no cure.
3. Clamped fins I believe is due to the tail and fin rot.
4. Swim bladder problems maybe due to the poor condition of this fish.

Advice and only if its in your heart (I read this in a book once and thank
God I never had to do it): If you see this fish with no response in a few
days or so, then and only then you should do euthanasia.

How to do it: Put the fish in a container with water, and placed it in the
freezer. The fish metabolism will slow down slowly and stop. The humane
thing about this is that the fish will not suffer, you will find it upright
and not in a contorted position.

I hope this helps.

Hi,

We own two goldfish and on Christmas Eve one of them seemed to fall ill
overnight. The head became swollen, the gills red inside, the dorsal fin
was
flat to the body and the tail was clamped. The fish has very restricted
movement and often falls over onto it's side momentarily before righting
itself again.

We immediately moved it to some fresh water in a separate bowl, to which
there was a very slight improvement. We bought some swimbladder treatment
which we have administered with some aquarium salt but this has not helped
in the slightest. Now the tail is rotting and appears very ragged. The
fish
will still eat if food is held sufficiently close for it to take

Does anyone have any suggestions please as from looking at the
www.goldfishinfo.com diagnostic guide it appears to be showing symptoms of
Gill Flukes, Clamped Fins, Tail Rot and Swim Bladder problems. I'm not
sure
whether I am able to effectively treat the fish in it's current condition.

The other goldfish has been absolutely fine

Thanks in advance for any help received
