Ok, so two years ago, I think, I got my first betta. I kept him in a little gallon bowl and I took care of him religiously. I fed him everyday after school and cleaned out his bowl every three days. But after a month or so I came home to find him dead. This really bothered me because I'd taken such good care of this fish. But after discussing it with my dad, we figured it must've been the salt from our water softener. So almost a year ago I got two more bettas, which I keep in five gal. tanks, and I've been using well water cuz I'm really paranoid about using water from the sink now. But sinse winter started, I've been having to run out to the barn to get the water cuz the hose in the backyard froze, which is frustrating. Sooooo after all that, my question is did my last fish die from the sink water, or was it something completely unrelated? It would be nice not having to walk all the way to the barn and back in the snow carrying a five gallon bucket.
