So I'm out fishing today, and movement in the water to my left catches my eye. I look, and to my amazement, I see this HUGE koi just cruising along a foot below the surface. I know it had to be a koi because it was pure white with black spots across its back. A conservative estimate is 19" and 4 lbs. I'm guessing it got turned loose in the lake and it seems to have thrived. So I'm wondering, what the heck would this thing be eating and what (if any) predators would it have?
