Ok guys, get this. I looked in my local phone book to see what other pet stores were in town and there is actually a shop that specializes in aquariums!! That's all they sell, fish & supplies. I had them test my water and it came out just fine. So I bought 2 more neons and they have lived more than 24 hours! Not only that, but they're pretty active little buggers. Yay! The other thing I did differently was acclimate them more slowly. Not with drip, but floating the bag, adding a shotglass amount of tank water, repeat every 10 minutes for about an hour and a half. So now I don't know if this helped of if they're just a healthier couple of fish. If all goes well we'll be adding a few more tetras of some sort next week.
