The test kit is going to give the best results but a quick google of Wyoming water hardness gave this result - can keep it that vague for locationAt this point I don't know and could not find on their site. It is probably in the water quality reports but that page comes up as not found.
Test kit is supposed to be here in three days so I guess I'll find out then.
"The average water hardness for the Wyoming resident is around 120 PPM. The city with the hardest water is Casper, at 208 PPM."
Which is really good as it means you have kind of neutral to soft hardness which gives you loads of options. I'm guessing from your previous fish that you prefer bigger character fish rather than smaller tetras and rasboras etc?
I'd be tempted by a pair of dwarf cichlids like Laetacara Dorsigera and have them as the feature fish and then you could have a school of something like Ember Tetras which are a really small growing species but colourful and due to the small size allows for a bigger school or you could go for a school of Marbled Hatchet Fish which would give the cichlids more space as they stick to the top. Having the school in the tank will give the cichlids more confidence and though unlikely with a Laetacara if there was any aggression it would get spread out amongst more fish.
