HI there, goldfish are know for eating plants, some do some don't, but java ferns, java moss, and anubias are often said to be safe. Mine hates her veggies, so she's safe with any and all plants, and I highly recommend anacharis. It grows so fast it can take some nibbling.
That being said, the minimum tank size for goldfish is 20gallons, and another ten for each successive gallon. That's only for fancies though, single tails need more.
Again, that being said, most don't even get ten gallons so, hey, as long as you know about the nitrogen cycle your goldfish will get better care than most
Are you sure there's no ammonia? Do you have any surface flow? Plants won't help much at night if you don't have any surface flow because they end up taking in oxygen instead. Personally I haven't tried hornwort but I've heard it's messy, but it could work
Edit: there are three main reasons that goldfish will gasp at the surface in order of most likely to occur.
1. Ammonia poisoning: the ammonia harms the gills and doesn't let the fish absorb as much oxygen
2. Oxygen deprivation: no oxygen means breathing is hard
3. This doesn't occur often, but sometimes goldfish that are fed flakes for too long try to "scavenge" for food at the surface and accidentally gulp air. Long term this can contribute to swim bladder disorder
temp stays between 69-72Also, what's the temp?
It's likely the reading is true, goldfish aren't that senstive and they'll try to mate in pretty much any water conditions. Go ahead and do a 50% today and tomorrow, and likely for a few more days. What's the exact ammonia reading? It should be at or under 0.25 during a fish in cycle, and should be 0 at all other times.
Did you dechlorinate the water?
Oh goodness. First, I am surprised your goldies are attempting to mate in a 10G tank. I would not spend a lot on trying to keep them in a tank either. Been there and done that. I had to move my comets to a 125G pond after less than 6 months. I moved them from a 10, to a 29, to a 55, and finally to the pond. They just don't work in a tank. I hate to be the bearer of bad news but I am trying to keep you from making the same mistakes and wasting the same money that I did. Find them a pond. If you like goldfish (kudos to you because so do I), buy a couple of fancy goldfish and put them in a 29G or larger, larger is better. By the way, the only plants that I have found to work with goldfish are amazon swords, anubias, java fern and hornwort. I hated hornwort at first but now I love it for goldies. It helps suck up the nitrates too. Mine ate Anacharis like salad. All I would have were stalks sticking up with no growth on them. lol
It was all zero when you got them because there’s wasn’t a source of ammonia. You have some ammonia problems so keep up the WCs.yeah I did everything to make sure the water was okay for them. I even tested the ammonia the first day I got them and it read zero

Do you have the pics?
Yeah, OP was told yesterday...
Anyway, I like that tank set up, I think it looks very nice. It's a shame that they can't stay in it.... If you can find a nice home for them we can help you restock it.
Keep up those water changes and keep that ammonia down, you'll get through this. Good luck!
Oh I totally forgot to mention: if you read 50 posts/replies you can list the goldfish here on the BSTF (buy, sell, trade, free) ( I may have messed up the letter order....) section and it's much more likely they'll go to a good home
I live on long island and also I can't post it yet I haven't met the requirements on here to do that :/
