Is Having goldfish and freshwater fish OK?

Goldfish are a type of carp, and they come from the cold, freshwater rivers and lakes of Eastern Asia. They prefer cooler water temperatures, ranging from 60-75 degrees Fahrenheit. Freshwater fish, on the other hand, can come from a variety of different habitats, and they may prefer different water temperatures, from tropical to cold.

In general, goldfish are more aggressive than other freshwater fish, and they may bully or even eat smaller fish. Goldfish also produce a lot of waste, which can quickly pollute the water and create a harmful environment for other fish.

Here are some specific examples of freshwater fish that should not be kept with goldfish:

* Neon tetras

* Cardinal tetras

* Rummy nose tetras

* Discus

* Angelfish

* Bettas

* Mollies

* Platies

* Swordtails

* Guppies

If you're interested in keeping goldfish, it's best to keep them in a species-only tank, or with other types of carp.

However, there are a few exceptions to the rule. Some freshwater fish, such as white cloud mountain minnows and zebra danios, are hardy enough to tolerate living with goldfish. Just be sure to do your research before you mix any different types of fish, and make sure you provide an appropriate environment for all of your fish.
