Hi!
It's greatful to know that people try to keep goldfish with plants. From my point of view, I am sure that this is possible and your case is a good example. However, I belive that a heavy planted tank is quite difficult to keep with big fishes. Some plants are weak and their stalks or leaves break easily when an adult koi or carassius moves itself between them. Perhaps, fishes can pull the plants up by the roots too.
If we have got in mind the parragraph above, I think that we have to choose strong plants such as Vallisneria gigantea, Crinum, Microsorium pteropus, Ceratophyllum demersum or similar.
It's my opinion
.
Yours faithfully,
