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.
None, goldfish are cold water fish, so having a tropical fish as a tank-mate just wouldn't work because tropical fish need to live in warm water.
Depends on the temperature
the water temp. must be quite warm
It depends on the fish. tropical fish need warm water, goldfish and koi like colder temperatures. You have to know what kind of fish it is to really answer this one. Ask the people you buy the fish from what temp it needs.
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.
Goldfish can not be pregnant. They lay eggs (spawn) in Springtime when the water temperature starts to warm up towards 70F.
Yes. They probably do. They are coldwater fish, so probably.
It depends on the goldfish.. For ones that stay small you should have at least 10 gallons.. The bigger the goldfish gets the more water it needs. Those one and two gallon bowls do not cut it..
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.
It is not recommended. Goldfish are cold water fish while tropical fish are warm water fish. Also, goldfish need to be fed more often than most tropical fish and they produce elevated amounts of waste which can be detrimental to fish not accustomed to it.
