goldfish vs. tropical

Hello goldfish keepers,

There seems to be the notion around that goldfish mustn't be kept with
tropical fish due to differences in temperature requirements. I am quite
certain it's not really true, as I've lived in sub-tropical Taiwan.
Temperatures are around 30 cel. most the year (dips briefly to +10 for a
month in winter), but goldfish are commonly kept and survive and thrive
(when properly cared for, of course). And goldfish are bred commercially
in southern China with a similar climate.

I think the reason goldfish aren't so good with tropicals is because
they're big and messy. Maybe goldfish survive less than ideal water
quality better than tropicals?

Speaking of goldfish and climate, I've settled in Europe now and
preparing to keep some goldfish in a big tub on my balcony. I know
nothing about overwintering. If it gets near freezing (but usually just
above) in winter, how should I go about reduced feeding, etc.? Can you
actually keep them in a big tub (50 gallons?) in this kind of weather?
Thanks,

Seb

50 gallons outside? It's likely to freeze over and kill your fish.
