Do goldfish fertilise internally or externally?

When goldfish breed, the male fish chase the females who dash around amongst the plants at the surface of the water. As they do this, the females release their adhesive unfertilized ova (Eggs) and these stick to the plants. The following male goldfish then release their milt (sperm) which is sprayed over and amongst the females ova. This results in the males "milt" comming into contact with the females "ova" resulting in the "external fertilization" of the ova.

How long does it take to fertilize goldfish eggs?

They are fertilised as they are spawned. As the females scatter their ova (eggs) the males, chasing the females, scatter their milt (sperm). Some will be fertilised immediately and others won't be fertilised at all. It's very hit and miss. That is why a female goldfish releases thousands of ova in a single spawning.


How do goldfish mate to reproduce?

The males chase the females in what appears to be a frenzy of action with both sexes dashing around at the surface of their pond amongst the water plants often jumping out of the water in their excitement. During this chase the females release their adhesive Ova (eggs) and the males release their Milt (sperm) which fertilises the ova as they stick to the plants. Depending on temperature the fertilised ova will develop into fry in around 3 or 4 days.
