yes you can
Yes, but your tank size needs to support it. If you mean that a regular goldfish is a long single-tail goldfish, then you need at least a 40 gallon tank just for the 2 fish due to the size potential of the common goldfish. If you mean a regular goldfish as in a round bodied fantail, or perhaps a ryukin, then you need at least a 30 gallon tank for the 2 fish.
One goldfish needs a 30-gallon tank, and an additional ten-gallons per additional goldfish. Goldfish can grow to be 10-12-inches long.
you would have to get a 10 gallon tank for 1 goldfish! you would need a 20 gallon tank for 2 goldfish. Also goldfish don't go well together there just being stored at the store they take the fish out right when they start to be aggressive. sorry bout your 2 gallon tank!!
You cannot put any goldfish in a 2 gallon tank.One fancy goldfish needs at minimum a 20 gallon tank on it's own. This is not just because of their adult size potential, but also because they are very messy fish and produce a high amount of waste.
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.
yes
No. A betta requires water between 80 and 86 degrees, while goldfish require water between 72 and 78. Also, there is not enough room for these fish in that tank. 2 goldfish should have a 20 gallon tank minimum to themselves.
Yes they can . Don't listen to any one They will be wrong!
If they are fancy goldfish (the plump looking ones) then 6 or so would do well in an 80 gallon when fully grown if they are common goldfish, then 2 maybe 3 when full grown would be ok as they reach a whole foot long! This may seem like its not many fish for a large tank however goldfish are real poo machines and good filtration is a must.
You cant. Goldfish need much bigger tanks. 20-30 gallons. I bought 2 goldfish when I was new to aquarium hobby and put them in a 5 Gallon tank. The first one died in just one and a half day. The other one died just hours after the first one :( So if I were you, I would get a bigger tank.
No, but it also depends on the size of the goldfish. I would say to go pick out 2 goldfish, put them on hold and go back home and see if you think they will fit, if you are still not sure, try bringing the tank to the petstore and ask them what they think.
It can't be done. Goldies get huge unless they are the facy kind. Try a pond or get five in a thirty gallon.
