Even a single goldfish will outgrow a fish bowl very quickly and with no filtration will be dead in no time instead of the quite long life time when kept in proper aquaria.
Just do it its cruel and unecessary.
betas, white cloud minnows, small cleaning shrimp, maybe even a goldfish for a few weeks before it out grows the bowl.
A fish bowl is not a solution its what you keep your goldfish/ beta fish in :P
My advice is to get an actual fish tank and not just a bowl. Fish bowls are cruel and don't have near enough space for 2 goldfish to live in
it depends how big the fish bowl is
If it is as old as a goldfish that can, it can.
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.
A small fish bowl is bad for any fish. You need minimal 5 gallon for a single betta. You need minimal 20~30 gallon for a single fancy goldfish, 40~55 gallon for a single common goldfish. Because fish produce ammonia and it is toxic to themselves. Goldfish has such large body mass, so they produce enormous amount of ammonia. You must have a good filter system, and do a nitrogen cycle first before adding any fish at all.
Goldfish are egglaying fish, so you would see several small white dots coming from her backend.
if your gold fish is small or medium fedd 3 to 4 small gold fish food
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.
Yes, provided the bowl is large enough.
A fish needs 20 litres in a bowl
