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.
A fish bowl is not a solution its what you keep your goldfish/ beta fish in :P
Zero, goldfish need very clean cool water and are very dirty fish.
betas, white cloud minnows, small cleaning shrimp, maybe even a goldfish for a few weeks before it out grows the bowl.
It's cruel to keep any type of fish in a goldfish bowl . So don't even try please . Fish that can live with Moors. Guppies (only if there is a heater in the tank) Common goldfish or shubinkin . And any other cold water fish and livebears
None 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.
it will live
You can put any fish that will fit into a bowl inside of one, but keeping is another matter. Much as it's potentially possible to keep a dog alive for a while inside of a closet, don't expect the health of the dog in the closet or the fish in the bowl to remain anywhere near optimal. Besides, fish have interesting behaviors you simply will not see in a bowl.That said, some species of betta will survive for a few years in a bowl as long as you are willing to do a lot of extra water changes. This includes the most common species, Betta splendens, which you often find sold in cups. As with any other fish, however, they do better in larger tanks with full filtration systems.Some might suggest the goldfish, but understand that even the shorter-bodied goldfish can grow to near a foot long if kept correctly, though it surely never will if kept in a bowl. Keeping goldfish in bowls comes from a misunderstood antiquated practice by the Chinese, who first bred goldfish. They kept goldfish in ponds normally, as is best for that species, and would occasionally put one or two in a bowl and place it on a dinner table as a form of decoration, to be put back out in the pond once dinner was finished.A better suggestion for your fish bowl would be to try making a small terrarium out of it; with a little soil and some interesting plants, you can create and maintain a beautiful little micro-environment you can enjoy nearly anywhere in your home.---------------------------------------------------------------------------------------------------It depends on the size of the bowl, but in a standard sized fish bowl you can keep toy fish, a can of tuna, gold fish crackers almost indefinitely.
Rule of thumb is to not mix tropical fish and goldfish.
Goldfish filters need to be on all day and night. Goldfish are the messiest fish around so do NOT keep it in a bowl. Besides filters also help provide oxygen.
It is NOT very right to keep a goldfish in a bowl. Not only do they become bored and unhappy, but it can cause health problems and stunt the fish's growth. However, the VERY least you can do for a fish in a bowl is the biggest bowl you can find. Also, goldfish NEED some sort of filter to live a reasonable amount of years, and filters cannot be put in bowls. I recommend at least a 5 gallon tank for your fish. Really though, there is nothing special you can do for a fish in a bowl.
No. Goldfish grow very large and are messy. Fancy goldfish need 20 gallons of water per fish plus 10 gallons for each additional fish (so 50 gallons at minimum for 4). Common and single tail goldfish need 30 gallons each plus 20 gallons for each additional fish
