Answer 2

Goldfish, like all fish are cold blooded. This means that unlike us, temperature effects them more drastically. Unlike most aquarium fish Goldies are a cold water species. Lots of times they are kept in tanks that are too warm for them. The most common way for problems in temperature to manifest itself in a goldfish are in the digestive system. Often different amounts of food need to be fed at different temps because the fish cannot metabalize the food properly. This can lead to constipation which often induces swimbladder problems.

Fish that are kept in poor conditions (too hot, too cold) are much more likely to get sick. This may not happen for a while. The fish might be happy for years but it will happen eventually. Goldfish should live a long time- up to 40 years. If a fish is kept in warm water he may live for 3. You can't really do a realistic study of this unless you plan on investing a lot of time in it. Years.

If you plan on doing an experiment on fish then you should have a discussion with your teacher about the ethics of science.

Answer 3

I have seen goldfish in a bowl that had to keep moving so ALL of their water didn't freeze solid. the bowl was slightly bigger than a basketball and these two poor freezing goldfish were swimming in a tennis ball sized patch of water that hadn't frozen (yet). The bowl was defrosted and they lived for 3 years after. Temps over 25 celcius will stress goldfish. 30+celcius will KILL

Answer 4

Goldfish are cold water fish and do best in a tank with a temperature in the range if 68-72 degrees. If it's to hot (like more of a tropical temperature) they won't survive as their systems are not compatible with the higher temps.

Answer 5

I live in Texas and have an above ground pond outside. I have goldfish in it and they have survived two winters in temps as low as 18 to 20 degrees. They don't need any heat indoors

Answer 6

Goldfish are not affected very much by the change in temperature. They are not very sensitive and usually don't need a heater in the tank to regulate the temp. They are pretty tough fish. There are fish that are very sensitive to temp., like angel fish for example. But goldfish are not.

Answer 7

The warmer the temp raises their metabolism which causes them to have more waist. They are cold blooded and like to have their water temp at about 72. Where tropical fish like it about 76 to 82.

Answer 8

they are a coldwater fish and prefer cooler water
unlike the tropicals that require warm water

Answer 9

If the water is to hot, you may boil them. If it is too cold, you may make goldfishpops out of them.

Answer 10

Under 32F you are looking at "fish sticks". Over 180F, stew.
