Can I pit these fish in a 29 gallon aquarium?

Updated results from the test. Ammonia is lowering and nitrates and nitrites are rising, so the cycle is going well.

But the ph is still very high.

So went ahead and tested the tap, and it pretty much explains everything...20221225_155219.jpg20221225_155850.jpg

I had to take two pics because one of my test tubes cracked 😥

So this means that my goldfish have been in this water for about 2 years! Will the goldfish be fine? And what can I do to stabilize the ph? Should I get tap water from somewhere like my grandparents house? (They use tap water)

I live in the Ozarks so and my house runs on well water. And I the Ozarks the water in the ground is LOADED with all kinds of minerals
 
Not much you can do about the pH - there are chemicals but once you start chasing numbers it’s a slippery slope imo.
Goldfish are tough - they should be fine.
The number one thing to do is pick fish that do best in high pH water.

So I guess I can't get any of the fish on my list..
 
Your grandparents likely have similar water. The best 2 choices are pick fish that tolerate high ph or use ro water. My lfs sells it in 5 gallon jugs, but I've never checked the price because it's more work than i want to put in

So if my area has this ph level, maybe I could just buy fish from local pet stores? I'd assume it would be the same water anyway

And again. Idk what fish that tolerate that ph could fit in a 30g

Sorry, yes, this is exactly what I meant by local . Often local fish stores also have the same problem so acclimatise fish to higher ph. Whilst it won’t work for all fish, there will be a large group that it may be just outside their range for so would still be fine. 7.4 is not bad. What concerned me originally was the dark blue which i would have guessed at much higher than this, 8 or even higher still, but if local water is only 7.4 then you should be good.

Thanks! I'll start with the platys, and get some drift wood and peat moss, and then I'll add the neons and gourami. That way the ph will lower somewhat.

Because a lot of people in my area have fish tanks, and the fish seem fine. So I was wondering about that. Again tank you so much for the info!
 
Again I'm no expert on water chemistry but IMO stability is more important than chasing a target ph. My tap is 8.2 and I kept a couple gouramis for 3 or 4 years until moving and setting up a different tank when i was young enouch to not know about water testing besides the basic cycle. This is a forum so you'll get a lot of opinions, and there's a lot of experience here, but it's your tank, and your fish.
