Can goldfish and tropical fish live together?

Goldfish are coldwater fish, while tropical fish are warmwater fish. Goldfish prefer water temperatures between 65 and 75 degrees Fahrenheit, while tropical fish prefer water temperatures between 75 and 85 degrees Fahrenheit.

If you try to keep them in the same tank, the goldfish will get too cold, while the tropical fish will get too hot.

In addition, goldfish and tropical fish have different dietary needs. Goldfish are omnivorous and eat a variety of plant and animal matter, while tropical fish are typically carnivorous and eat live food or prepared food specifically designed for tropical fish.

Goldfish will also often eat the small fish that are common in tropical fish tanks.

Finally, goldfish can be quite aggressive, while tropical fish are generally peaceful.**

Goldfish can easily injure or even kill tropical fish, especially if they are kept together in a crowded tank.

For all of these reasons, it is not a good idea to keep goldfish and tropical fish together. If you want to keep both coldwater and warmwater fish, you will need to set up two separate tanks.
