came home to find 2 of my fish lying at the bottom of the tank it did need cleaning but put it off till i come back from a holiday so i grabed them out of the tank into clean water with the other two i caressed them and dragged them backwared i knew they were'nt dead as they were'nt floaters but they were on their sides i was trying so hard not to loose them and they say that goldfish have a two second memory they are wrong!!!!because my other two fish kept them going by bumping them to keep breathing and making sure that they staid up on thier side and not on thier side and they are alive and swimming now thank-goodness they say that dolfins do this but MY GOLDFISH DO IT TOO!!!! it's got to be love
