Puffer fish are very aggressive fish and will tear the poor goldfish to pieces.
Yes they can, I have a guppy (amongst other fish) with 4 goldfish together and they are very happily living together :)
no
Rule of thumb is to not mix tropical fish and goldfish.
The size of a goldfish tank can affect the growth of the goldfish. A larger tank provides more space for the goldfish to swim and grow, leading to healthier and potentially larger fish. In contrast, a smaller tank can restrict the fish's movement and growth, potentially stunting their development.
it depends on how big it is if it is a goldfish or beta it can be in a bowl.If it is one of those big tiger fish or aqarium fish then put it in a big tank. A fish will grow to the size of the tank or bowl. For instance, say a goldfish is in a tank, it will not grow as big as the tank; however it will grow big enough to be able to swim in their environment. The fish will not overgrow the tank. I had a six inch goldfish in a thirty gallon tank.
Goldfish do not get pregnant.
Yes they will, to prevent this you could buy a fish tank cage.
No, goldfish are freshwater fish. Any goldfish you buy in the store are tank bred and not wild caught.
an aquarium or a fish tank
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.
A total of four mollies can be found in the water tank
