ur right.. its not the same. people who measure their fish have to wait a much longer time for their fish to calm down in order to measure them. during that period, the fish will be flapping on hard floor causing harm to itself in the process as well as becomming more and more stressed. if the fish continues to struggle, the person has to manhandle the fish to make it stay still. After all that, the fish will finally be put back into the water. For my piranha however, it will be taken out of the water for only a few second, take a bite, and put back into water. hm... i wonder which one is more tormenting...
