My 55 gallon fish tank has just finally finished the stages of nitrite and bacteria colonies so right now my ph is at 8.1 and it seems to be completely stable and i was wondering if that ph it suitable for piranhas. I know people say that a good range for piranhas is around 6.8 and 7.2, but i also hear ph around 6.5 and 8.3 are ok as long as you keep the ph stable. So i was wondering if thats true or not.
