Another fish story: There used to be a couple of koi carps in a pond at my mother's place, one red, one white. One day, the water pump stopped working, and, as the oxygen level in the water was dropping the fishes started to suffocate. When we realized the problem, the white one was already almost belly up. Barely breathing, and unable to move. The red one could still swim, but he was tilting. We brought out the water hose to agitate the water and oxygenate it. It created a current that sent the white fish drifting down and away in while the red one could stay afloat in the safe zone. We tried to alternate the spraying between both, but the white one kept drifting away from the fresh water. To our surprise the red koi started to bring back the white one from the bottom to the surface. He the kept lifting the other in a corner. He probably saved his pal's life. Both recovered, even though the white one kept a 15 degrees tilt for the rest of his life.
