I'm looking for opinions on whether I can get tetras with a stable pH of 8? Everything I've read says that they need a more acidic environment. Yet the pH at the store is also close to 8 and they say it doesn't matter. I really don't want to get into livebearers even tho I know this may be my only option with my ph. Any opinions wecome! Tank is 10 gallons, btw, and they would be the only inhabitants.
