You really don't. You have to wait until breeding time for fish outside and fish in tanks they can breed any time depinding on the water timperature
It depends, if the goldfish are all males (or females) no, but if not of course they can mate.
no it will not mate in any couse
when you get it a mate.
when you get it a mate.
No they can't.
Of course! Goldfish reproduce sexually not asexually
The best and only good tank mate for fancy goldfish, are other fancy goldfish.
No
No they are not goldfish
yes, goldfish can mate, if you keep your goldfish in a pond... they usually mate in spring, and if you keep your goldfish in a tank, they may mate anytime... but they usually dont do this until they are 3 years old, when they mate, the male will get breeding tubercles which looks like pimples but not red, then they will do a chase, when the female get tired she will release her eggs and the male will fertilize them. of course, you can also try to find ways to make them breed though... anyways... as animals are... they can pretty much all breed including goldfish!
no. you should have 10gal of water per goldfish. you shouldn't have goldfish in a 5gal tank at all. they are huge waste producers
The male goldfish will get white spots on it's gill cover, and the female will start looking swollen because she has eggs inside her. Sadly though, most times when goldfish mate, they eat their eggs and you will get no young. If you try many times though it will probably work! Hope this helps!
