I just edited my post, it actually took 9 drops for my aquarium water to turn green, so its pretty hard. Not sure it 5 was put in.That is OK, the the bottom line is, the GH is very soft whether it is 3 or 5 dH. Each drop represents one degree dH.
Mollies cannot live long in soft water; other livebearers are the same, though mollies are especially sensitive and fairly quickly show symptoms. Clamped fins, shi8mmying swimming, resting on the bottom are all symptomatic of the fish not being able to function due to the lack of minerals.
The other fish that are soft water species (neon tetras were mentioned as one) will be fine in this GH. The issues to harden the water at their expense are not advisable.
So Mollies and Tetras have different water hardness preferences, and tetras like soft water, mollies like hard water? In that case, the tetras in the tank maybe having issues with the hard water that I haven't noticed. Another question, if my tap water is so soft, why is the aquarium water so hard?
