Hmm, well I dunno. If you properly accustomed them to your tank, the pH is fine as long as they arent super sensitive fish.
Sometimes the colors are hard to read in pH test. Depends if either one of you used liquid or dip sticks.
I never quarantine my fish either.
I am iffy on buy from small business... cuz they dont really have the 14day guarantee thingy like Petsmart/Co. And they tend to be more stict that petsmart/co cuz they dont make much money I guess.
Petsmart/Co sometimes test the water but I have never ran into a problem with my water... But anyways it's easy to cheat the test water, just prepare some "clean and right" water before going to the store.
