It should be a cold temprature that is quite cold for you hands but the fish can also live in warm water to but dont really like it!!
Mostly 60 to 80 degrees is their ideal tempature.. but they can survive in colder temperatures
Goldfish is a cold-blooded animal. It's temperature is the same as the water around it.
i think it is 74- 78 degrees
18 - 20 c
Unchlorinated water, such as bottled distilled water is best.
The water should be at room temperature.
Goldfish spawn in groups in springtime when the water temperature approaches 70F. They do not have live babies.
Just leave the aquarium at room temperature.
I am guessing that you mean a Plecostomus. The answer is NO. Each of the species needs totally different conditions. Goldfish are cold water fish and suffer when the temperature goes over 75F. Plecostomus are tropical fish and suffer when the temperature goes below 75F. They will both survive for a while in one anothers parameters but eventually they will die from living in the wrong conditions.
You should keep the water at room temperature.
well, not long. i had a goldfish and it died in like 8 hours.
They start to come into breeding "mode" when the temperature gets over 65F.
it depends on what type of fish.a goldfish has to be in room temperature water.
They can but they shouldn't. Gold fish like colder water and guppies like warmer water. They can live when the water temperature is in that in between range when they are both not comfortable.
Goldfish are best kept at a temperature of at least 74F to 76F. There are times that you might increase the temperature to a tropical fish level for a short term to treat an illness, but you should not have it too warm.
There is no such thing as a 'Tropical Goldfish'. Goldfish are a coldwater species. Their prefered temperature is above 50F and below 65F. The fish respond to a slow rise in temperature over a week or so from around 65F to about 70F during Spring/Summer by spawning.
