Have you ever done this?

I was abit curous about fishless cycling so i decided to investigate it. 10 I bought feeder comets, 7 survived during the transportation. Then, i put them in my tank without cycling, raw tap water and watched for 4 months. I thought they were going to die, but i was wrong. They were healthy,hyper active and a bit rowdy. Have you kept your fish in raw tap water and uncycled tank?
