He he he!
People on Koiphen say if U want your fish to spawn...play Barry White!
Now it has scientific relevance, and We were just joking about it!
I am just not sure how music sounds to Koi under water...and what is the reason they stop moving, and as a result storing (not using) the food.
Another thing is how good is that for them?
Maybe good for carp for eating...but Koi? Is it not better for them to exercise?
I am going to post it on Koiphen as a joke ( the link)
