Hey /an/
I have a ten gallon aquarium, and I really want to get a school of about 6 neon tetras to put in it. The problem is that my water is really hard (250ppm), and the lowest pH I've been able to get from it is 7.0 after adding extra pH regulator tablets. Is there a small (1-2in mature size), schooling fish that can survive in hard freshwater, ideally that doesn't require a heater? I was also looking at white cloud mountain minnows, but it looks like they can only live in 200ppm water at most.
Any advice would be appreciated-- thanks!

Rosy red minnows. Don't use ph tablets, they cause a crash.

pH 7 is neutral, not basic. Most (70% or so) of living organisms can chill between 6.5-7.5, but I know jack about tetras.
If the tablets you used were buffers, then anon is right, they could lead to a sudden spike in pH when the fish excrete ammonia which has a high pH.

Oh, thank you! I added a very big chunk of driftwood, and today the pH went down by 0.2 points, to 6.8. The water is brownish so I hope it is the driftwood-- but I'll keep monitoring.

Right now I just have 3 ghost shrimp and 4 snails in the tank. Will I be able to cycle the tank with them inside? I established the tank 24 hours ago.

Yeah the driftwood does a pretty good job with keeping the pH lower and can add those wood tannins and all that into the water most amazon fish like.
You can try aquarium peat too if it's not enough or to pretreat the water for changes.

Oh gorgeous! Yeah, I'll definitely grab some at the store. Thanks!
