I had one of my koi customers of many years test me tonight to let me know she lost all of her koi last night. We had major thunderstorms and her yard took several lightning strikes. Yard stakes that supplied power to pond were blown up. Her pond was a converted pool to pond. She and her neighbors have holes in the yard from lightning. She is on the water so don't know if that made the condition worse. I have been trying to catch my 1 & 2 years olds to rehome them and because we lost power to the one pond with the excess fish, decided to drain it down while cleaning filters that had been down for probably 8 hours. Caught 6 fish and have 12 others in a holding tank waiting for a new home. This works out well for both of us. I rehome my excess koi and she gets her pond restocked. Its amazing how some things work out!
