Input (English): Passage: I realized that I had n't fed my fish yet yesterday afternoon . The fish is a Beta named Tom and he is bright red and blue .

Tom immediately swam to the flakes that were slowly sinking down into the water and began to nibble at them . Satisfied , I replaced the cover on the top of the tank and watched him eat for a few minutes . I then screwed the fish food lid back on and put it back inside of the drawer underneath his tank .
