I wonder why you are loseing so many. Has your city done anything to the water? My aunts city did something to their water and people lost their fish, and other animals due to whatever they put in it. It seems something is going on. Maybe get some water from another source for now until you can rule out your city water. I hope you don't lose eva to!
