Just thought I would share something I thought was funny. I have my discus tank acroww from the kitchen in my studio. I recently discovered that while the fish get excited me or my girlfriend walking by, as we both feed them, if either of us open the freezer where the blood worms are kept, the discus go balistic. I knew that fish associate things with food, but I never realized that they would look all the way across the room, and start associating an open freezer door with a meal of blood worms.
