No!!!! Why would someone do such a thing! They need coldish water!
If it is a sudden temperature change, yes. Maybe not if you give them a really long time to really slowly change the temperature... not recommended, though.
'''NO WAY! They will probably die very very soon then. It's just like putting them in cold water. Either they freeze to death or they burn to death.'''
They prefer cooler water, but yes, they can live in warm water
Yes just don't put it in really hot water like 78F put it around 70F
Yes they will grow bigger
Depends on the temperature
Some species of goldfish can survive in 0-degree water, but most goldfish won't survive in water below 10 degrees C. The fish would probably survive a while but would eventually stop moving and die.
cold is better cuz when your in the ocean is the water hot or cold cold
Technically , both require different environments. Goldfish likes cold water and angelfish likes tropical. However, goldfish can survive in warm water so both can be kept, leaving one of them unhappy.
Simply put, they will die. Goldfish are coldwater fish and if their water gets too warm, their metabolism speeds up. Their bodies then demand more oxygen for them to survive. The warmer water is, the less oxygen it can contain, so coldwater fish simple die from lack of oxygen in warm water.
Goldfish are meant to live in cold water, not the warm water in a tropical aquarium. This is a huge reason why goldfish and tropicals shouldn't be in the same tank.
No. Like all members of the carp family, goldfish can survive in a wide range of water temps.
Salt water, water that is too hot or cold or has chemicals in it
No, absolutely not! Brackish water has salt water in it and it will die because of that!
Goldfish are very hardy fish and can survive a wide range of water conditions. It wouldn't surprise me if they were the last fish to die after a major tank/water problem.
Goldfish need water to swim and breath in, not mud. There are some species of fish that have evolved to survive in mud but Goldfish are not one of those species.
the water temp. must be quite warm
