It should be between 63 F and 72 F. :) .
The water in a goldfish bowl should be changed at least once a week to maintain the health of the fish.
To ensure the health of your goldfish, it is recommended to change 25-50 of the water in the bowl every week. This helps maintain water quality and keeps your fish healthy.
It should be fine.
A guppie is a tropical fish and should be kept in an aquarium with other tropical fish, a goldfish is kept in a bowl or tank in cold water - the 2 cannot be kept together because of the different in the temperature of the water
Yes, like all pet fish, goldfish need more oxygen than can be provided by just a bowl of water.
Bettas are. Goldfish really should have an aquarium if you want them to live.
Zero, goldfish need very clean cool water and are very dirty fish.
The goldfish would need to be removed from the iron bowl and placed in a temporary home. The iron cannot be seal without making the water to toxic for the fish. A small pond liner should be used instead. This will provide a water proof barrier between the iron bowl and the water.
A fish bowl is not a solution its what you keep your goldfish/ beta fish in :P
A fish bowl is not a suitable receptacle for keeping fish in. A goldfish in a bowl will not live for long. To avoid temperature and chlorine shock water should be stood in a container beside the bowl for a few hours to equalise and allow chlorine to evaporate off. A bowls water should be changed at least 2 times daily to avoid ammonium poisoning of the fish. The minimum recommended size aquarium/tank for a goldfish is a 15 gal nominal tank. (goldfish grow to at least 10 inches). Bowls were used during the 1800 and early 1900s when people were uneducated and ignorant and did not know what is known today about keeping fish.
it depends how big the fish bowl is
betas, white cloud minnows, small cleaning shrimp, maybe even a goldfish for a few weeks before it out grows the bowl.
