If you intended keeping soft acidic water fish, some species would not last long in your tap water, others would "adapt" to some extent. The stress caused to fish by any environmental aspect that is significantly different from their natural preference does affect the fish's physiology and causes health issues and a shorter lifespan.
Are you sure this wasn't a carry-over from another tank you had, or someone else's thread?
Yes, you're right, it started with my first tank. I eventually got it right so I started a 2nd tank. I kept mixing water in the 2nd, forgot why, and got confused. Now I think I have myself under control. thanks.
