I picked up a gorgeous male Jack Dempsey, about 5 inches long, a month ago. Since I have had him I have only seen him ingest food once. He just swims around at feeding time and looks at everything but seems to have no interest. He hasnt lost any weight but I am not sure whats going on, I have had demspeys in the past and they were nuts when it came time to eat? Maybe he is living off of scraps left behind when I am not around? Everyone else in the tank is eating great! He is even the biggest in the tank.
