Beginner's Pet Freshwater Fish

10 Pet Freshwater Fish for Beginner

Keeping an aquarium in your home has various health benefits, including stress reduction and blood pressure reduction. Freshwater tanks are typically easier to maintain than saltwater tanks, and their inhabitants are more tolerant of mistakes made by new owners. Freshwater fish have their own exquisite collection of colorful and distinctive species that will fill your aquarium with life.

Here are some of the best beginner fish to consider.

1. Goldfish (Carassius auratus)

Goldfish

The Goldfish is a lovely kind of freshwater fish that may grow up to 14 inches long in the wild. Some wild goldfish can survive for up to 25 years or more! Beginners should start with long-body goldfish, including the comet, sarasa and shubunkin varieties.

Fancy goldfish are preferable for more experienced fish owners. Comet goldfish can be white, orange, gold, or black, and can grow to be 14 inches long, or the size of a big dinner plate. Sarasa and Shubunkin tend to be smaller, reaching a maximum size of 8 to 10 inches.

Your pet Goldfish will thrive in a tank of at least 20 gallons in captivity. These fish require ongoing care, such as weekly water changes and filtering. Goldfish come in a variety of shapes, sizes, colors, and breeds.

2. Neon Tetras (Paracheirodon innesi)

Neon Tetras

The neon tetra is a small, slender, and low-maintenance freshwater fish that is suitable for new owners. They don’t grow very long, only reaching 2.2 cm in length! They are well-known for being a gentle and tranquil animal. They thrive when kept in groups and in tanks with rocks, plants, and other hiding places. Neon Tetras are easily identified by their brilliant red stripe along their bodies and blue bodies.

Because neon tetras are easily bred in captivity, watch for symptoms of inbreeding such as missing operculum’s (gill covers), asymmetrical mouths, or malformed fins. Pelletized meals that are tiny enough for Neon Tetras are available, although flakes can be substituted for very little fish.

3. Mollies

Mollies

Mollies are a nice freshwater species that are small and easy to care for. Mollies can grow to be 3 to 4 inches long and are omnivorous, meaning they can consume both plants and animals. What’s fascinating about this watery animal is that, unlike other fish, it gives birth to its young.

Even beginner fish keepers can successfully rear several generations of fish, doubling or tripling their initial numbers in a matter of months. However, you will eventually need to slow output, and unmonitored breeding will result in inbreeding.

Most mollies, thankfully, are sexually dimorphic, and males and females can be differentiated by outward traits. This enables you to separate males and females in order to prevent populations from exploding. You can use a tank divider, but it is safer to separate males and females.

4. Guppies

Guppies

Guppies are extremely easy to care for, however they breed quickly if the genders are not separated. They appear in a variety of colors, with males being more colorful than females. You can use a tank divider, but it is safer to separate males and females. Guppies are popular because they can adapt to different water conditions and have vibrant personalities. It is critical to maintain a stable water temperature so that they can live peacefully in their environment.

5. Betta Fish

Betta Fish

Although the have the reputation as one of the easiest freshwater fish to keep, your betta will live a long, happy life with a few upgrades from their sad, little bowl. Bettas thrive in five-gallon tank minimum with a filter and heater. Being tropical fish, bettas should be kept at 78 to 82 degrees Fahrenheit (26 to 28 degrees Celsius).

The bigger the volume of water, the easier it is for your heater to keep a constant temperature. Make sure your tank has a thermometer, and not those unreliable stick on ones! With their long, delicate fins, bettas are prone to being knocked about by quick flowing water. Use an appropriate size filter and turn the flow all the way down or divert it so your betta doesn’t get pushed around.

It is recommended that beginners begin with one male fish in his own tank. Bettas are simple to care for when housed in a larger tank. Extra water allows beginners to have a more relaxed maintenance routine. Your filter and heater will go a long way toward creating a pleasant betta environment.

6. Angelfish

Angelfish

Angelfish are popular freshwater fish that may reach lengths of 6 inches and heights of 8 inches. They’re quite pretty and come in a variety of colours and patterns. They can consume plants and other creatures such as small insects and shrimp, but they should be kept away from small fish. Angelfish can be territorial and aggressive, so keep them in a tank with few other fish.

7. Zebrafish (Zebra danio)

Zebrafish

The Zebrafish is a small and low-maintenance freshwater fish that grows up to 5 to 7 centimeters in length and is ideal for beginners. Because they are schooling fish, they must be kept in groups or they will get extremely anxious. Zebrafish enjoy eating worms, insects, and crustaceans. They can also be fed regular fish flake meal, although we recommend spicing it up.

Unlike many other pet fish, zebrafish don’t like warm, tropical temperatures, so do not use pre-set heaters! Zebrafish like room temperature water (around 70 degrees Fahrenheit, or 21 degrees Celsius), so you may need a small heater to keep your tank from getting too cold in the winter. These fish critters are known for jumping out of tanks, so be sure to keep your tank covered.

8. Rainbowfish

Rainbowfish

Another less common freshwater fish that is easy to care for is the Rainbowfish. Their brilliant hues don’t really stand out until they reach adulthood. Nonetheless, with careful care and maintenance, it is well worth the wait. These fish might be quite shy, although they are usually placid in their aquariums with other fish. Barbs and tetras get along well with rainbowfish.

9. Platies

Platies

Platies (Platy fish) are beautiful freshwater fish that come in a variety of unusual colors. They are normally gentle fish that flourish in groups. They get along well with guppies and mollies; they’re quite gregarious! Platies require a combination of plant-based and protein-based diets, while they can also consume meat-based diets.

Even beginner fish keepers can successfully rear several generations of fish, doubling or tripling their initial numbers in a matter of months. However, you will eventually need to slow output, and unmonitored breeding will result in inbreeding.

Most platies, thankfully, are sexually dimorphic, and males and females can be differentiated by outward traits. This enables you to separate males and females in order to prevent populations from exploding. You can use a tank divider, but it is safer to separate males and females.

10. Golden Dwarf Barbs

Golden Dwarf Barbs

The Golden Dwarf Barbs is a lesser-known freshwater fish that is perfect for beginning aquarium keepers. They can grow up to 1.5 inches in length and are easily identified by their golden yellow colorings and black markings on their bodies. Golden Dwarf Barbs flourish best in tanks with plants. In a tank, no more than 5 of these freshwater species should be kept.
