I got a couple of guppies, a male and a female, Friday afternoon. I also got 6 neons at the same time. They all went into my 29 gallon tank with my 2 glass catfish. Everything seemed to be fine over the weekend, but Monday evening both of my guppies mysteriously died. They just seemed to get weaker and less lively over time, and then they died about the same time. All my other fish are doing fine, and my water pH is just slightly above neutral. Any suggestions?
