Pond Tips - Fish Breeding

 

The usual time for Koi and goldfish to reproduce is when the water warms
in spring. If you want to help ensure survival of baby fish, provide a safe
haven for the eggs and fry (baby fish), as the adults will eat as many as they
can get. This safe haven can be roots of plants like Water Hyacinth, Water Lettuce,
or soft filter material. Also consider that too many fish can lead to poor water quality.
