Goldfish Community.

Provided you have a tank big enough for the goldfish and bear in mind that the goldfish will get big enough to eat panda cories.

By a big enough tank, I mean at least 100 litres for the first fancy (double tailed) goldfish and an extra 50 litres for every additional fish. So 100 litres for 1, 150 litres for 2, 200 litres for 3 and so on. Common (single tailed) goldfish and comets need even bigger.
