A while ago we took some tiny recently born goldfish from the outside pond
and have kept them successfully for a couple of years in an indoor
aquarium.

Recently one after another have started 'folding up' and drifting around
helplessly although still staying alive for four or five days.

Would anyone have an idea what this is? Can we put the remaining fish
outside with the others, or have they likely been infected with a disease
of some kind?
Thanks for advice.



I've had a look in Goole and founf this page which might help:-
