I suspect Cyclids would do fine.

Hi,

Apart from Koi and Goldfish, what other fish can I keep in an outdoor
pond that can handle the water temperatures at least 9 months of the
year?

I live in Sydney, and in summer, the water temperature is typically
~71 degrees. In winter, the water temperature is ~62 degrees. The
pond I am building to keep them in will be about 450 gallons and 3.5
feet deep.

Han.
