One goldfish needs at least 20 gallons, and then it's an additional 10 gallons per goldfish added after (so 30 gallons for 2 goldfish).
This is not only because of the size that they can grow, which is big, but also because they are messy fish and produce a high amount of waste
No. A one gallon tank is not appropriate for a singular goldfish much less multiple. A ten gallon tank is the bare minimum for a singular goldfish and breeding would require a tank of twenty gallons or more. A one gallon tank cannot handle the chasing that proceeds goldfish mating nor maintain a water quality that is suitable for raising goldfish fry.
It depends how big your bowl is if it is below 5 gallons then you should put one. But if it is 1 or 2 gallons then you will have to move it into a 5 gallon tank or bowl at the least.
Goldfish do not get pregnant.
They prefer one.
Aslong as it has enough room and filtration many types of goldfish can be kept together. There are some cases where problems occur as such as the case with Sarassas and Orandas. Sarassas will tend to nibble at the cap of the Oranda causing damage.
No. Unless you put it in a tank with sand.

One goldfish needs a 30-gallon tank, and an additional ten-gallons per additional goldfish. Goldfish can grow to be 10-12-inches long.
1 inch of fish requires 1 gallon of water. Work it out.
No you schould not have that many fish in a one gallon tank. Thats the size of a big betta bowl. And because they are goldfish it is worse their poops are toxins
No, one goldfish needs 20 gallons alone at minimum, plus an additional 10 gallons for every goldfish you wish to add. This means that for two goldfish, you need at least a 30 gallon aquarium.
