Answer 1

yeah fancy goldfish don't like strong currents, mine did when she was a baby, but now that she's older she doesn't like it as much.

i think plants, my goldfish doesn't bother the plants (she used to eat them bare, but they've grown back).

and real plants are more natural and give more oxygen to the water.

it's really whatever you prefer.

and only one goldfish should be kept in 20g.
