Fish Update: Our 3 swordtails are doing just great. We went to Petco yesterday to pick up some more fish. I brought some water for them to test and they said everything was fine except for my PH, it's too high. That meant I couldn't get any fish that day. I bought some goop that's supposed to bring it back down to a healthy range. I also bought my own testing kits so I can find out that my water is bad before I drive 45 minutes to Petco.
