Wal-Mart Theft Deterrent System Kills Fish
I’m really not a Wal-Mart hater. But I have never heard anyone have any luck with fish from Wal-Mart. I got fish at Wal-Mart before and they didn’t last very long, they got sick, yadda yadda, it just didn’t work too well.
I was told that when leaving Wal-Mart with your happy new fish that you must lift the bag above the security gate. These theft deterrent systems create a magnetic field that you must walk through when leaving the store and that your fish must also go through. These fields don’t affect us, I’ve never died after leaving Wal-Mart or anything other retailer with such device. But fish are totally different from us!
I stumbled across an article that tested the effects of the magnetic fields from electric lines on fish. The results were that the fish died. I find this interesting. [article] Maybe there is some fact for magnetic fields and fish death. In the article the fish died 1 to 2 years later, but she was not using magnetic security gates, which I feel would be much stronger.
I don’t know for certain if there is a correlation between fish death at Wal-Mart and security gates, but I think it is an interesting question to pose.

No wonder why my fishes die so quickly!!! Thats nice to know.
I have an aquarium at home and we bought some fish for it at Wal-mart and they died quick and we didnt know why but now I do!!!
Thanks for the info. (nice blog)
