Dan, it is much easier to suggest which fish to stock your tank with if you know at least the basic water parameters of your tap water.
At a minimum it's nice to know what the pH and hardness of your tap water is so that you don't need to worry about having to buffer or adjust the pH or hardness for the fish you end up getting.
You can usually get these water parameter results from your local water company website or you can take a sample to your local aquarium store or buy an aquarium water test kit yourself. Naturally hard or soft water supply can determine what species would work best for your needs.
Do you have city water or a private well for your water supply?
Nobody is trying to be difficult in their responses, it's just the normal answers when someone asks what fish should be purchased.
