I placed a cotton mop head in my pond last weekend hoping the fish
would spawn. I have just discovered some foam at the surface of the
water and went to check out the mop and found light yellow eggs on the
bottom. Would these be Koi or goldfish eggs? How do I know when
they're fertilized? What do I do now? I only have Koi and goldfish and
its a 1300 gallon pond in Maryland. Please Help. Thanks.
