Hopefully this will not make any of you jealouse, it is in S. Cal and
it is 90 degrees, On Super Tuesday 3/9, I found millions of Koi eggs
attached to the string algea in the pond. very exciting.
There comes the question: how do I know those eggs are fertilized or
not? a few days ago I did notice two male (I suppose) was chasing the
famale (I know for sure) Koi .

I already moved the string algea (with eggs) to a seperate tank
