I remember as a small boy growing up in central Texas, my grandpa called his pond a tank. Not sure why. But it was small and lined with cattails or reeds of some type, a sand bottom, it was firm, not soft. And we would wade out so the water was just below our chins and splash water on each other. The first time a small sunfish pecked on me I thought it was a snake, screamed and swam as fast as I could. But my grandpa only laughed and sent us back out there, telling us to be still and watch the sunfish come up to us and peck. Said they were cleaning the parasites off our skin. Lol. I donâ€™t know about that now, but the memories have remained fresh in my mind.
