Would two of those goldfish need a pump? Would I need to suppliment
their insect food with other food?

Is your concern the cost of power or getting power to the pond? If the cost
of power, you can get air powered filters that will bubble in the pond,
look in the aquarium section, you'll probably want a powerful pump so you
can run 2-3 of filters, as they're small.

I run a little 90g/hr pump in a DIY bucket filter with a bell fountain, I'm
sure it uses less power than a 50 watt bulb.

IMO, get small fish, rosie reds, or guppies, that you don't have to feed.
The feeders probably would do okay without being fed, but don't put dunks
in the pond, or they won't get much food. ~ jan
