A cold-blooded animal's body temperature depends on that of its environment. Since fish live in water and water maintains a relatively stable temperature (compared to land), fish have survived for many years with this cold-blooded feature. Not all fish live in the same waters, however. A fish that can survive in chilly northern waters will not survive in warm, tropical waters and vice-versa. Furthermore, all fish, including goldfish, are naturally from a body of water larger than a goldfish bowl. Even if you have a hardy goldfish, you need to make sure his or her water stays at a relatively stable temperature. Personally, I think all fish, including goldfish, should be in a temperature-controlled aquarium that simulates their natural environment and gives them room to swim.

because they are cold-blooded animals... which means they can not maintain their body temperature. Their body temps are regulated by their surrounding so they would naturally adapt to the cold water environment.

Because they are not mammals. mammals with legs are warm blooded, well, except for reptiles. Good luck!

It is simply the way this life form evolved...
