Best way to indroduce new fish??

It's the fact that they were swimming around, checking everything out, playing, etc.. for 30 minutes before they dropped like flies. It makes me so sad :(
 
Yup, Goldfishfreak is right. It's strange how these things work out sometimes. I have had experiences where I did everything possible and my fish still died within days of their arrival. On the other hand, when I was a small child, my family was moving from Toronto to Ottawa (about a 4 hour drive) and all we did was pack up my 10 gallon tank, put all the fish in jars, then when we got to Ottawa we filled up the tank, plugged everything in and dumped the fish in and they survived and thrived for years.
 
So is there nothing else I should do? Just monitor pH and amonia levels until Thursday?
 
Yashinfan,

Was your ph pretty close to the ph at the lfs? The only time I have seen a mass die like that after such a short time was introducing fish to a vastly different ph. I would be very surprised if the water from the store had any effect. It sounds kind of anal, but every time I bring fish home from the store, i check the ph in the bag.
 
These fish did not have any sort of visible disease and were healthy in the tank in the LFS. I asked the woman to check the pH in the tank and she's like, "It's normal." This time I will force her to check my tank and their tank to make sure it is compatible. If it's not, then I won't buy the fish until it is. So the way the fish died is that one of them started spinning, or like giving in to the water current? Then she floated to the top dead. The others soon followed altho one managed to fight it for a couple of minutes. I'm pretty sure it was because of the pH, no other tests showed any other problems. If my tank was 8.0 and the LFS' was something like 7.2 & 7.4 it might explain their deaths.
 
You know I sincerely doubt that the pH was the case of death . I moved my fancy goldfish(more delicate than a danio) from a pH of 7.2-7.4 to one that was 7.8 and my fish showed no signs of discomfort.
 
Omg, don't say that!! What do you think it was then?!!
