There are over 10,000 species of freshwater fish and many of them are kept as aquarium fish. In general, freshwater fish tend to be hardier and easier to take care of in comparison to saltwater fish. Since they tend to be less demanding, their tank setups are usually more affordable as well. These diverse group of fish come in many different sizes, display a wide spectrum of colors, and have interesting characteristics. Some of the most common types of freshwater aquarium fish are cichlids, rasboras, catfish, plecos, tetras, loaches, arowanas, betta fish, and gouramis, just to name a few.
