Cold water fish like gold fish prefer water in the range of 64-68. Warm water fish like guppies like 70-74 and can be even higher.
they get cold
No. The temperature variation will kill one or the other. (Too warm for cold water fish, too cold for tropical fish)
Yes. Depending on the fish, but all fish can freeze if the temperature of the water reaches a certain temperature.
The warm water fish could go into hyper drive and their little hearts beat so fast and can die. Cold water fish have no problems with very cold water.
Goldfish are "coldwater fish" their comfortable temperature range is 55F to 70F. The stimulus to make them breed is when the temperature rises to over 65F.A gold fish needs cold water.
because it has something to do with there body`s the water has to be at a certain temperature or the fish will die sorry :(
Fish are cold-blooded so their body heat change with the temperature of the water.
In the case of the rare fish that must have water below a specific temperature there are water coolers (refridgeration units) available commercially. its called a chiller & they are rather expensive. if you have fish that require low temperature you will require one or death is immanent
Room temperature.
Yes, a perch is a cold blooded animals, as are all fish, as their body temperate rises and falls with their environment. This means that when the perch is in warm water, their body temperature rises to match it and when it moves to cold water, its body temperature lowers.
If the water temperature is too hot or too cold, your fish will be stressed and may die.
Most fish are cold blooded and their body temperature matches that of the water in which the are immersed. However i believe the Great White Shark (and some other predatory fish) can maintain a body temperature higher than that of their environment.
