That's really hard to say for sure; I would think they might like at least one goldfish friend, but this means that you need to have at least a 30 gallon tank.
yes
People consider Goldfish as good friends too. But they are fishes and cannot socialize back.
One goldfish requires at minimum 20 gallons on it's own plus 10 gallons for each additional goldfish (30 gallons for 2 goldfish). It's not only because of how big they can grow, but because they are very messy fish & produce a high amount of waste
That you need a new goldfish
No, goldfish are not bait; or as Bruce from Nemo would say "Fish are friends, not food"
there are three basic breeds: fantail goldfish, comet goldfish, and common goldfish. if you are getting goldfish for the first time, i would recommend common goldfish as they need the least care.
The answer is no. People usually think that goldfish get lonely and depressed. This is not true. Goldfish are fine on their own! People usually prefer 2 or more
goldfish need to lay eggs. Because if they don't no goldfish would be alive and would not be any more so they would become gone forever.
Yes, goldfish are very messy. Goldfish need 10 gallons per fish, you actually need a 20 gallon tank or about a 70 liter tank for 2 goldfish. But the small tank will do while they are small, you will need to eventually get a larger tank.
Tom has a Goldfish; a present from friends last Christmas.
Well yes you need a male goldfish and a female goldfish to have babies but it takes allot of time to breed them.
Regardless of the type or size of goldfish the minimum acceptable size of an aquarium for a goldfish is 30 gallons. Buy a tank that is at least 30 gallons if you plan to have goldfish. You can comfortably fit 3 goldfish in a tank this size but no goldfish in a tank any smaller. Goldfish are essentially pond fish and need lots of space to swim; they will not thrive in a small aquarium.
The goldfish should never be in the same tank as guppies. Goldfish are coldwater fish and need to be kept below 70F. Guppies are tropical fish and need to be kept above 70F.
