mork and mindy where did you get the fish from it is very rare to get a bad fish from either wet pets or animates they know what they are doing and do it very well, and one of the employees (owners daughter i think) at tabithas is in the p nth aquarium club. It could be that you didn't acclimatize the fish properly
One thing i learnt that was bad was floating the bag in the water, as a bag holds such a low amount of water the temperature fluctuates way too fast, and as the fish have been to the toilet in there the amonia content with the quick heat jump will posen them (or stress them giving them white spot).
I also come from palmy so if you need any help feel free to pm me and ask and i can come around and lend a hand
