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
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.
Rule of thumb is to not mix tropical fish and goldfish.
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
