Freshwater Aquarium Fish

There are over 10,000 freshwater fish species, many of which are kept as aquarium fish. In general, freshwater fish tend to be hardier and easier to take care of than saltwater fish. Since they tend to be less demanding, their tank setups are usually more affordable as well. These diverse groups 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.
