Yes, but only for a very short time, for goldfish are known to grow rapidly.
Goldfish need plenty of room to swim around and get very large. In a 1000 gallon pond you could put 25-50 goldfish just keep in mind that goldfish grow very large and need about 20-30 gallons each when full grown.
You may want to add a liner to be on the safe side, but you could have 2 fancy goldfish, one one common or single tailed goldfish. (goldfish grow big and fast)
Wouldn't recommend putting a goldfish in a 5 gallon tank-regardless of what type or size of goldfish. This is because the goldfish would be stunted causing it to have an untimely death. The condition in which a goldfish is "stunted" is where the fish adjusts to its tiny environment so much as to stop growing. The fish will stop growing on the outside but will continue to grow on the inside. Goldfish are naturally messy and create a LOT of waste. This factor would cause the tanks water to be poluted which inturn could kill not only the goldfish but possible your mollies too :(. Two mollies is enough for a five gallon tank. If you truly want to get a goldfish you will have to house the goldfish in a 10-20 gallon tank with very good filtration
You could have a school of neon tetras (approx 6), or 1 fancy goldfish
another gold fish or try asking someone in a pet shop that sells fish maybe they can help
Only if the "feeder Goldfish" - which is usually just a mutt bred Common/Comet Goldfish, is very small and the Telescope is an adult. If it fits in their mouth, that's where it will end up! However, "feeder" Goldfish have the potential to get over 10"-12" excluding tail fin, and a large one of these could very easily fatally injure a more fragile fancy Telescope Goldfish. The two varieties should never be mixed.
Tri Color Rex and Mini Rex COULD be called Calico I guess.
Every Second! Gold Fish are Very messy and need a filter to keep them alive. I suggest you put your Goldfish in a pond. Make sure there is more than one, Goldfish have friends just like you and me. Or you could get a 20 gallon tank (the tank has to be big enough so goldfish can grow up to 10 inches long WITH a filter. okay long story short, one inch per fish needs at least a gallon!
If you are going with freshwater tropical, it you could add 55 inches of fish. Goldfish, on the other hand need 2-3 gallons per inch, about 22 inches of goldfish.
You could, but it is very dangerous because the beta would eat the gold fish. 🐠🐟
Follow the 1 inch per gallon rule, for every ince the fish is long, that is how many gallons the fish needs to live in. If you wish to get a neon tetra (2 inches) you could have 1, but a tetra is a schooling fish and needs to be kept in groups of 5 to 6. You may want to consider a betta fish, you could have 3 females in the tank or 1 male. (bettas and goldfish are an exception to the 1 inch rule bettas need 1 gallon, goldfish need 10 gallons)
It is classed as a very small tank and could only house about 5 inches of fish. (1 goldfish is a 10 inch fish)
