My livebearer tank's pH is around 7.6, as is my tap water.
pH is really not nearly as important as the hardness(with livebearer's). pH numbers simply give one an idea as to what the mineral content may be in a sample of water.pH below 7.0 often suggest's softer water than ph of 7.5, to 8.0 which normally indicates moderately hard to hard alkaline water.
It is the latter that livebearer's thrive in.
