When it comes to keeping a pet, freshwater aquarium fish are some of the most popular choices. In addition to being low maintenance and easy to care for, they also make great companions. With that in mind, you should know what to look for when buying a freshwater fish, as well as some essential information about caring for your new pet. Read on to learn more.

What to Look for When Purchasing a Freshwater Fish

Before you even think about getting a freshwater fish for your home, you should know what to look for when buying a freshwater fish. This will help you to avoid making common mistakes. For freshwater aquarium fish, you will generally want to avoid those that are very small or very large. Also, you should only buy an adult if you are buying a pet. Younger or larger fish often require specific care that is not appropriate for most people. Therefore, it is best to stick with smaller or juvenile fish. Lastly, you should also make sure the fish you buy is suitable for your specific aquarium setup.

Some freshwater aquarium fish

There are many different types of freshwater aquarium fish that are suitable for beginners. The variety of freshwater aquarium fish available will make it easy to find one that will suit your taste as well as your aquarium setup.

Silver Angelfish

Among freshwater angelfish, silver angelfish have long been a mainstay. It is the color variation most closely related to the “wild type” of the species P. scalare. These angelfish are hardy and easy to care for. The three vertical black bands can fade or darken dependent on the mood of the fish.

Bronze Cory

There are many Bronze Corys available everywhere, and they are very popular. These two classes of Corys are hands down the most commonly kept members of this family. There are several color morphs of bronze Corys, such as green, bronze, albino, and black. It is recommended that they be kept in schools since they do well in a wide range of conditions.


Guppies are all-rounder fish species that make suitable pets for beginners. If the genders aren’t separated, they tend to breed with each other quickly. They come in different colors, with males being more colorful than females. Guppies can also familiarize themselves with various water conditions and have active personalities, which is what makes them so popular. 

Betta Fish

The Siamese fighting fish, or Betta Fish, is another popular choice for freshwater aquariums. Colors abound, and they tend to be easygoing for the most part. Betta fish are known for their aggressive behavior toward other fish, particularly males. If your Betta fish is serene enough, they can be kept in a large tank with other fish species. Avoid retaining them in tanks with similar-looking fishes like guppies. You must also place them in their own tanks, ample with substrate and plants. 

How to Care for Freshwater Aquarium Fish

The best way to care for your new freshwater aquarium fish is to research what they need and what they prefer. This is the only way to make sure they live happy, healthy lives. While there are some general guidelines, you should also keep in mind that each fish is different. For example, many freshwater aquarium fish prefer a specific temperature of water that is between 74 and 80 degrees Fahrenheit. If your home’s temperature is too low or too high for this temperature range, you can simply adjust your aquarium’s water heater or heater to make sure it is in the correct range. 

Similarly, you will also want to make sure the water in your freshwater aquarium is clean. This means that you will want to make sure that you change the water in your aquarium at least once a week. This is because water that sits in an aquarium for long periods of time can become polluted with bacteria and algae. These bacteria and algae can be harmful to your fish and even cause death if they make it into their bloodstream.


If you are interested in keeping a freshwater aquarium fish, these are some things to keep in mind. You will find that they are easy to care for and make great pets. In addition, they make great decorations and can serve as conversation pieces when guests come over. Once you know what to look for, you can easily find the right fish for your home.
