Hello! My father-in-law and my wife & I built a 12'x9'x4' deep pond in 2006. He put all the koi that he had been raising for years in it. Since then, we've had a few spawnings, and we tried to save and grow as many of those new koi as we could.
We had a horrible die-off about 7 years ago, I think we lost 2 dozen over the course of a week! I've always been careful about keeping the filter clean, watching the water temp for feeding, etc. No trouble since then.
We still have about 2 dozen koi, most of them 24" long or bigger. They are so relaxing to watch, sometimes I sit on the edge of the pond and watch them do their thing.
