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.
Goldfish don't have babies, they lay eggs. They usually do so in the spring.it takes up to 45 minutes
As soon as the male serves the hens then the eggs should be fertilised.
a fancy goldfish leaves the eggs in the stomach for about 3 month's... after that it can take up to 5 months to lay eggs after that.
Goldfish can not get pregnant. They are egg layers. The female sprays thousands of eggs into the water in the breeding season (spring) and the eggs are fertilised by the males after they have been sprayed out. The eggs then take a few days to develop into baby fish (fry).
The answer is yes. Fish do need at least one male in the tank to fertilies the eggs. However in some cases the fish will first lay the eggs then the male will fertilize them.
Goldfish don't get pregnant.

You would need to put goldfish eggs in a separate tank, and yes, you may have to take the goldfish eggs out of the main tank where all the goldfish are, because the adult goldfish will eat the eggs. However, you can just cover the goldfish eggs in a plastic see-through box while being inside of the main tank if you don't want to take it out, just in case you may harm it, and the fish won't be able to eat it.
