Somebody breeding fancy goldfish sort of oddly. Might like to try.

I saw somebody post a video of this guy breeding goldfish by rubbing his thumb up against the fishes sperm ducts. I however did not see the guy get the female to lay out eggs. I may of not seen the whole video. Can anybody tell me where to find information about how to perform this task without harming the fish? I would almost hate myself if I accidentally hurt the insides of the fish. Just curious about how to do this.

Okay. I just found out it's called hand-spawning.

I think your right Childawg. I don't think it's such a good idea. The old fashioned way is better. More of a surprise in my opinion.
