The only thing I would change is adding a hood. Goldfish can and do jump. It will also allow you to provide light for that plant. It looks like an anarcharis which needs pretty high light. I would also add some more decor. One of the reasons the oranda might be stressed out is that it feels too exposed. A goldfish without an appetite isn't a healthy fish.
I knew they get pretty chunky yes, but a few months? I've heard they grow a bit slower in an aquarium situation vs a pond. If this is because of the waste produced that's why I left it bare, so I can easily siphon the bottom every few days. If they do end up having trouble with this tank I will fix it but I figured they'd be fine for at least a year or two.
Plant is fake and I want to leave plenty of open swimming room. I recently did a good cleaning of the entire filter and nice water change and Oranda seems to be eating and feeling himself again.
