Solar Thermal Geothermal large pond heating with giant Koi Fish hot water GreenPowerScience

This simple water delivery solution to cold spells worked wonderful this year. The large koi fish were/are 10 years old introduced in 2002. They usually hide most of the time and were impossible to capture because the pond center approaches 15 feet deep.

  2. Can a large Koi fish eat humans?

  4. I just watched your video I live in metro Tampa and have never had the problem to a degree that you did it breaks my heart. We have had some of our smaller female Koi and a very large beloved Gold fish die from the inability to absorb three eggs. My Koi actually spawned this morning for the first time in 3 years. We had been battling fish lice for that entire time period and were taking a huge toll on the health of the fish. We lost 2 of our 10+ year old females due to the lice one was a off spring from a spawning and was hand fed her entire life. Sorry to hear that you lost fish as a result of this I know it can be a hard thing to deal with.
