Can you put a goldfish in tropical fish tank with fish?

It is not advisable to put goldfish in a tropical fish tank with other fish. Goldfish are coldwater fish, while tropical fish are warmwater fish. The ideal water temperature for goldfish is between 65-75°F, while the ideal water temperature for tropical fish is between 75-85°F. Goldfish also produce more waste than tropical fish, which can pollute the water and make it harmful for other fish. Additionally, goldfish are aggressive fish and may attack other fish in the tank.
