Beautiful Fish Species For Your Living Room Aquarium

Having an aquarium in your home has many health benefits, including stress and blood pressure reduction. Freshwater tanks are easier to maintain than saltwater tanks, and their inhabitants are more tolerant of newcomers’ errors. Freshwater fish come in a wide range of colors and varieties, ensuring that your aquarium is brimming with life.

It’s difficult not to become infatuated with your freshwater fish and their distinct personalities, whether you’re a novice or a seasoned aquarium owner. Let’s take a look at the top ten freshwater fish to add to your aquarium.

  1. The Neon Tetra

The Neon Tetra is a small, thin, and easy-to-care-for freshwater fish. It’s probably one of the most well-known freshwater species on this list. Neon Tetra are small, only reaching a length of 2.2 cm! They’re known for being calm and friendly animals. It’s best to keep them in groups and in tanks with rocks, trees, and other hiding places. Neon Tetra is easily identified by their bright red stripe running down their legs and their blue bodies.

  1. Some Guppies

Guppies are yet another fish species that make excellent first-time pets. They’re incredibly simple to care for, however, if the genders aren’t divided, they’ll breed with each other quickly. Males are more flamboyant than females, and they come in a variety of colors. Guppies are common because they can adapt to a variety of water conditions and have vibrant personalities. It’s critical to maintain a stable water temperature (around 50°F – 84°F (10-29°C) so they can thrive in their tanks.

  1. A few Mollies

Mollies are a perfect freshwater species that are easy to care for because they are small and easygoing. Mollies are omnivorous, meaning they consume both plants and animals, and can grow to be 3 to 4 inches long. This freshwater critter is unique in that, unlike other fish, it gives birth to its young. Mollies, like Guppies, love to breed, so if you don’t want a lot of these lovely fish in your tank, keep just one gender.

  1. Maybe The Betta Fish

Another common freshwater aquarium fish is the Betta Fish, also known as the Siamese Fighting Fish. They come in a wide range of beautiful colors and are, for the most part, laid-back. Betta fish, particularly males, are known for being aggressive and territorial with other fish. Betta fish can be housed in a large tank with other fish species if they are peaceful. Avoid putting them in tanks with other fish that have a similar appearance, such as Guppies. You should also put them in tanks with their own substrate and plants.

  1. The GoldFish

The Goldfish, another common freshwater fish, is a stunning species that can reach lengths of up to 14 inches in the wild. Some wild goldfish will live for up to 25 years or more! In captivity, your pet Goldfish can live in a tank that is at least 20 gallons in size. These fish need ongoing care, such as weekly water changes and the use of a filter. Goldfish are available in a wide range of shapes, sizes, colors, and breeds.

  1. The Angelfish

Angelfish are common freshwater fish. They can grow up to 6 inches long and 8 inches tall and are members of the Cichlid family. They’re very lovely and come in a variety of colors and patterns. They eat plants and other species, such as small insects and shrimp. 

Therefore, placing them in with small fish should be avoided. Angelfish can be territorial and aggressive (though not to the same degree as a Betta fish), so hold them in a tank with few other fish.

  1. Golden Dwarf Barbs

The Golden Dwarf Barbs is a lesser-known freshwater fish that’s perfect for new aquarium owners. They can reach a maximum size of 1.5 inches and are easily identified by their golden yellow coloration and black markings on the body. When kept in a tank with plants, Golden Dwarf Barbs thrive. In a tank, no more than 5 of these freshwater creatures should be contained.

  1. Rainbowfish

The Rainbowfish is a less popular but easy-to-care-for fish. Their bright colors don’t really start to show up until they’ve reached adulthood. Even so, with proper treatment and care, the wait is worth it. These fish can be shy, but they are usually peaceful in their tanks with other fish. Barbs and tetras get along swimmingly with rainbowfish.

  1. The Zebra Danios

The Zebra Danios is a small, low-maintenance fish that can grow up to 7 cm in length and is an excellent choice for beginners. They must be kept in groups because they are schooling fish; otherwise, they will become very nervous. Worms, insects, and crustaceans are favorite foods of Zebra Danios. They can also be fed regular fish flake food, but we suggest spicing up their diet. Since these fish critters have a habit of jumping out of ponds, keep your tank sealed.

  1. Some Platies

Platies (Platy fish) are beautiful freshwater fish that come in a variety of vibrant colors. They are usually peaceful fish that do well in groups. They get along well with guppies and mollies, and they’re really friendly! Platies need a variety of plant-based and protein-based foods, but they may also consume meat-based foods.


As a new aquarium owner, or a more experienced one looking for a variety, it is important that you know the behavior, feeding habits, and water requirements of each fish species before you throw them in. 
With freshwater fish, it is important that you keep the aquarium clean, the water well filtered, and ensure they’re well-fed. As for your filtering needs, consider buying aquarium filter pads in bulk that will help you keep your aquarium clear and clean while also ensuring cost-efficiency in your maintenance endeavors.
