New tank for Goldfish
 
Set this 20g long up the other day with an established filter. Take a look and see if there's anything I'm missing as far as their health. I keep it a bare tank for easy cleaning for now. Oranda hasn't been eating much lately.

If the tank is a temporary setup, it looks pretty good. I don't know if you are aware but oranda and black moores tend to get larger than most fancy goldfish and top out at around 10-12 inches long. The 20G long will hold them for a few months, but they'll need an upgrade after that.

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.

Well it will also depend on the quality (and quantity) of food you feed them. Keep the tank on the cooler side around 70F, and it will slow their growth. You'll certainly need to upgrade in under a year, tho. Goldfish grow the fastest in the first year of life.

There might have been a slight ammonia spike, but I'm glad your oranda is doing better. A hungry fish is a healthy fish.
