thanks for understanding. but i still believe livebearers are mostly raised in 7.5+ ph tanks, and 200+ hardness.The tank looks lovely and you're doing a great job. The fish will be appreciating the effort you've made to their home ? I think Sgooosh was offering advice based on wild habitats rather than aquariums. Naturally you won't have water as acidic as found in the wild, but your PH is neutral for an aquarium which isn't a problem. Your general hardness can dictate whether your fish are thriving, which is why I requested it to insure that your set up runs smoothly.
It was just a simple mix up ?
7.4 should be just fine if all are local fish
