Don't try this method unless you have some skill and apply only when the fish have started agitation in the tank. We will take every fish in hand and we will gently squeeze in the anus region. If eggs comes out is a female and if a white smoke comes out is a male. The fish of which nothing comes are not ready for spawning or are not sexually mature and we will put them back in the tank. Having the fish sex separately we can begin "milking" operation.
Prepare a 10-15 liter tank, maximum 10 cm height, with an air pump. The water should be put in the tank 2-3 days ago with a 20-22° C temperature. Take one goldfish of different sex in each hand. With both fish bodies in the water, we gentle massage their belly, from head to anus. Will come out eggs from both female and male, fertilization being done immediately. We repeat this massages until nothing comes out.
"Milking" will be done easy and careful, not to break the fish bladder. After finishing this operation, the fish will be introduced in the tank and will be fed. Usually, goldfish start breeding at 4-5 o'clock in the morning, so if you want to practice this method, you'll have to wake up early.
The water from the breeding tank will have a misty appearance due to eggs from male. After 10-15 minutes, we will change the water from the breeding tank (don't worry, the eggs are sticky on the glass and will not fall) with clear water at the same temperature. Now, all we can do is wait, everything is just like at a natural breeding.
Bellow is a movie to make you understand better the hand spawning.
