This is not my first time around guys. I know. I have been keeping FW fish for atleast 5 years. I believe the frog i got started with a deformaty and thats what killed it. And i think stress killed the gourami. My parents made me move the tank the night before, then i did a water change, then his friend kermit died, then i had to pull him out of the tank because my parents wanted me to break the little 5 gallon down (would have done anyways), and then i started acclemating him to a new tank. So yes, i am pretty sure that i knew what killed them. Besides i was behind on 1 water change do to me having a family emergency, so that didn't help.
If you guys read closely i made a joke, Flake asked my water parameters and i said 0 on everything because i broke the tank down by that time so there was no way to know. As for using tap water, I never do, i try to avoid this always and i haven't used tap in years. I use a water machines water from a small market like 5 min away. And if i do i let it sit 24 hours and use dechlorinizer.
