Goldfish need to mature before they can lay eggs and they can get pretty large (6" or more). By the time they are large enough, they have outgrown a fish bowl. So technically, the answer is no. You will need large goldfish in a large tank before you can breed them.
Yes, provided the bowl is large enough.
A fish bowl is not a solution its what you keep your goldfish/ beta fish in :P
it depends how big the fish bowl is
The cheapest way to keep a goldfish is to keep it in a fish bowl.........as long as the bowl is big enough the fish will be happy there.
No, goldfish do not stay with their eggs. After spawning, goldfish typically scatter their eggs in the water, and they do not provide any care or protection for the eggs or the resulting fry.
As long as that plastic bowl is large enough to fit in x amount of fish you have and you fill it with an appropriate amount of water.
Goldfish bowls make great 'floating flower' vases. They are absolutely useless for keeping fish in. The first rule of fish keeping is "1 inch of fish needs a minimum of 1 Gallon of water". Goldfish bowls are therefore not large enough to house one tiny fish.
immediately separate the eggs from the bigger fish with a screen. The bigger fish WILL eat them.
A fish needs 20 litres in a bowl
Yes, like all pet fish, goldfish need more oxygen than can be provided by just a bowl of water.
Fancy goldfish need 10 gallons per fish while common and single tail goldfish need 20 gallons per fish. The fish need more space, and they need to be around 3 years old before they are old enough to breed. The fish will be around 4 to 5 inches long w/o tail when they are the right size to breed. A bowl is not the proper home for a goldfish they are too large and messy of fish to live in a bowl. Once they breed you will have around 100+ fry (baby goldfish) that will be 1,000+ gallons of water that will be needed to raise them.
