Thinking about getting an aquarium and filling it up with freshwater fish? We’ve got all the info you will need to get started in our freshwater aquarium fish guide including the best freshwater aquarium fish. We will make recommendations on which freshwater aquarium fish to get (for beginners and experts) and also the conditions you will need to maintain a healthy aquarium for the fish to live and thrive in.
When it comes to keeping an aquarium there are a number of choices that determine how easy your aquarium will be to take care of as well as how difficult the fish that you choose to keep will be to take care of. Many beginner aquarium keepers decide to go with a freshwater aquarium due to the fact that they are easier to maintain without buying the most expensive equipment. Keeping a simple freshwater aquarium gives the benefits of keeping an aquarium without the cost of purchasing an elaborate setup.
Important Things to Remember About Keeping a Freshwater Aquarium
While many people may claim that keeping a freshwater aquarium is simple, when working with a basic aquarium set up there are certain aspects that you should keep in mind in order to help your aquarium to thrive. It is important to remember that the temperature of any aquarium needs to be maintained within a steady range in order to support the life within the tank. Most people are able to maintain the required temperature for the fish selection in their aquarium; however, many people neglect the plant life that they place within their aquarium which is equally as dependent upon the temperature of the water. It is crucial to select fish that thrive within a similar temperature range as well as plants that can be maintained in this same range in order to promote the optimal aquarium atmosphere. The average temperature for a freshwater fish community is between 72 to 82 degrees Fahrenheit. For plant life the average temperature falls between 76 to 86 degrees Fahrenheit.
The pH (aka potential of hydrogen) of the water in the tank is also another important factor for any aquarium. Different types of fish require different pH balances in the water, while some thrive in a much more acidic atmosphere others may not. It is important not to mix fish that require a more acidic aquarium with those that require a less acidic aquarium in order to promote the health of your fish. Mixing two varieties of fish that have different pH requirements will eventually lead to the death of one of the fish types within the aquarium. As with temperature, pH is another factor that not only influences the health of fish within the tank, but it also affects the health of plant life within the tank as well. The average pH of a freshwater fish community is between 6.5 and 7.5; the average pH requirement for fresh water plant life is 6.0 to 7.5.
Other Elements of the Freshwater Tank
While the temperature and the pH balance of the aquarium water are important, there are also numerous other factors which also play an important role in keeping an aquarium community healthy. In order to determine all of these elements you must invest in a water testing kit that will allow you to track these elements within the water of your tank. Some of the elements that should be measured using these home testing kits include ammonia, nitrite, nitrate, alkalinity and general water hardness. Within a freshwater aquarium the fish community requires ammonia and nitrite levels both to be at zero, nitrate levels to be at less than 50 ppm, alkalinity to be between 4 to 8 KH and general water hardness to be between 4 to 12 GH. Many amateur aquarium keepers find the initial water balancing to be intimidating or even overwhelming; however, a home testing kit and a water treatment formula can quickly and easily rectify any discrepancies in the values that are required for a healthy aquarium.
Populating a Freshwater Aquarium
Many people turn their nose up at the idea of keeping a freshwater aquarium rather than a salt water aquarium because they believe saltwater life to be much more interesting and diverse. While there are differences between the types of fish that can survive within fresh water versus saltwater, there is plenty of diversity that can be attained by selecting only freshwater fish to populate an aquarium. The most important factors when selecting freshwater fish are compatibility and experience. If you are seeking to combine a variety of different fish breeds in your aquarium it is important to select fish that are compatible which means not combining aggressive fish with peaceful fish since this would lead to a rapid death for the peaceful breed of fish.
Experience is another important factor in selecting the fish that you desire for your aquarium since some fish are considerably easier to take care of than others, even in a freshwater environment. For an inexperienced aquarium keeper to select a breed of fish that is recommended for experienced aquarium owners would not only be a frustrating experience but it would also be an expensive one. Fish that are recommended for expert handling only are done so for a very good reason, they are not hardy fish and require much more experience and knowledge about fish than most beginners have. While there is nothing to stop a beginner from purchasing a much more advanced fish breed, these fish are often expensive to purchase and without the right level of care they can die quickly resulting in a very expensive lesson.
Freshwater Fish for Beginners
There are a number of aquarium fish types that are particularly recommended for beginning freshwater aquarium owners, these include: glofish, cichlids, betta fish, goldfish, barb fish, and guppies.
Glofish are a type of Danio fish that are recognized for their “glowing” ability. These fluorescent fish glow in a dark tank and are becoming increasingly popular as a starter fish for children who wish to keep their own freshwater fish tank. The glofish are peaceful fish and should only be placed with other peaceful fish that thrive in water between 64 to 75 degrees Fahrenheit with a pH of 6.5 to 7.5. The glofish requires an omnivorous diet and grows to around 2 1/1 inches requiring a minimum tank size of one gallon.
Cichlids are a popular fish for beginners as well and they come in a wide variety of variations, one of the more popular is the electric blue cichlid.

The electric blue cichlid requires an average tank temperature of 76 to 82 degrees Fahrenheit and a pH of 7.8 to 8.6.
Betta fish are one of the more popular fish for first-time fish owners. These colorful fish are peaceful; however, when it comes to housing them with other betta fish things become difficult. Male betta fish are extremely aggressive towards each other and they also should not be housed with female betta fish except for a short period of time during breeding. When adding a betta to an aquarium it is likely that one male betta fish will remain in the aquarium; however, some people find they can house multiple female betta’s together without issue. One of the more popular breeds of betta fish is the crown tail betta which is known for its unique tail design. The crown tail is a carnivorous fish and can grow as long as 3 inches putting the minimum tank requirement at 1 gallon for this fish.

Which Fish Are the Right Choice for Your Aquarium?
Many people go in to their first aquarium buying experience with the belief that they can only purchase fish of a certain breed to populate their tank, this is untrue. While you are restricted by the temperament of the fish that you select for your freshwater tank you do not have to select all one breed of fish to populate the tank – in fact, this would lead to a rather boring aquarium! Jump into diversity with your freshwater aquarium and try matching different fish breeds to create the ultimate freshwater experience, just keep in mind that in order to have a healthy aquarium you should match fishes temperaments as well as their requirements. Select fish that are compatible with your experience level and compatible with each other and you will have no problem growing a thriving freshwater aquarium environment.

An Overview of Freshwater Aquarium Ownership
While many people may lead you to believe that owning a freshwater aquarium just simply isn’t as much fun as owning a saltwater aquarium, this is a matter of opinion. Freshwater aquarium owners can experience just as much diversity in their fish as saltwater aquarium owners can and some freshwater fish are even more aggressive and picky than some saltwater fish! Ultimately, the choice as to whether you should go with a freshwater or saltwater tank should be based upon personal preference and not the opinion that one tank has “better” fish to offer, because this simply isn’t true.
