hi
i gonna tell you the about habbits..
Goldfish natively live in ponds, and other slow or still moving bodies of water in depths up to 20 m (65 ft). Their native climate is subtropical and they live in freshwater with a 6.0–8.0 pH, a water hardness of 5.0–19.0 , and a temperature range of 40 to 106 °F (4 to 41 °C) although they will not survive long at the higher temperatures. Indeed, they are considered ill-suited even to live in a heated tropical fish tank, as they are used to the greater amount of oxygen in unheated tanks also the heat burns them.
In the wild, the diet consists of crustaceans, insects, and plant matter.
While it is true that goldfish can survive in a fairly wide temperature range, the optimal range for indoor fish is 68 to 75 °F (20 to 23 °C). Pet goldfish, as with many other fish, will usually eat more food than it needs if given, which can lead to a fatal intestinal blockage. They are omnivorous and do best with a wide variety of fresh vegetables and fruit to supplement a flake or pellet diet staple.
Sudden changes in water temperature can be fatal to any fish, including the goldfish. When transferring a store-bought goldfish to a pond or a tank, the temperature in the storage container should be equalized by leaving it in the destination container for at least 20 minutes before releasing the goldfish. In addition, some temperature changes might simply be too great for even the hardy goldfish to adjust to. For example, buying a goldfish in a store, where the water might be 70 °F (approximately 21 °C), and hoping to release it into your garden pond at 40 °F (4 °C) will probably result in the death of the goldfish, even if you use the slow immersion method just described. A goldfish will need a lot more time, perhaps days or weeks, to adjust to such a different temperature.
Because the goldfish likes to eat live plants, keeping it with plants in an aquarium can be quite a problem. Only a few of the aquarium plant species can survive in a tank with goldfishes, for example Cryptocoryne and Anubias species, but they require special attention so that they are not uprooted.
