Depends on how many goldfish you have. You don't want to over crowd ur tank or fish bowl. And make sure you put somethin that makes bubbles in the tank so that there will be plenty of oxygen in the tank

I own 4 goldfish: one small, one medium-sized, one big, and one extremely large. Someone who worked at a local Petsmart store said that you only need 1 gallon per every inch of a goldfish. (goldfish tend to be extremely dirty) However, we didn't listen to the person. We bought 4 fish, and a 2.5 gallon tank with a filter. They're fine. Try to get a tank 2 gallons for 2-3 fish, and if you get more, get a 3 gallon fish tank or up.
There is a basic rule for keeping any kind of fish and that is The minimum water requirement for 1 inch (2.5cm) of fish (body length) is 1 gallon (4.25ltrs) of water. It is also best to know how large the species of fish will grow. In the case of Comet Goldfish they can grow to over 12 inches so allowances for growth should be taken into consideration.
Goldfish don't need salt because they are Freshwater Fish!
Because a comet is a single tailed goldfish, and can grow very long, it will need at least 30 gallons on it's own
It depends on the goldfish.. For ones that stay small you should have at least 10 gallons.. The bigger the goldfish gets the more water it needs. Those one and two gallon bowls do not cut it..
About 2/3 or 3/4. Basically depends on the size.
My Fantail Goldfish did that alot the first time I got him. I think it might be that they need to relax or they might be scared.
You need to provide 1 gallon of water per inch of fish. Goldfish get along fine with other goldfish.
No, a goldfish will not kill a betta but they should NOTbe housed together. First of all, bettas are tropical fish, meaning they need temperatures of 75-85 F while goldfish are cold water fish and need much lower temperatures. Also, bettas are usually quite aggressive and territorial so I would not risk housing him with a goldfish.
HOPE THIS IS HELPFUL
goldfish will survive in tap water but it is best to put a bit of chlorine control in the water plus you will need a filter if you want the water and tank to stay cleaner for longer :)
It depends on the fish. If its a tropical fish that is accustomed to salt water, you need salt water and you need to keep the water at a warmer than norm temperature. If its just a regular goldfish, freshwater at room temp should do just fine.
your goldfish might die and maybe eat to much or the water starting to get dirty
Yes, like all pet fish, goldfish need more oxygen than can be provided by just a bowl of water.
