If you’re a beginner, there are several reasons to start out with a freshwater fish tank. Freshwater fish are much cheaper than saltwater fish. They also require less maintenance. This makes them a good choice for the beginning aquarium hobbyist.

Catfish, for example, are a great choice for your first fish. Plecos, which grow to large sizes, are another excellent choice. 

Rainbowfish are also a great choice, and there are many different varieties of these species to choose from. Afterward, you can expand your aquarium by adding other species of fish.

Betta Fish

If you’re considering getting a fish for your first aquarium, there are a number of reasons you should wait before getting a Betta.

For starters, your aquarium is not ready to be filled with live animals right away. You need to wait for the nitrogen cycle to kick in before adding any fish to the tank.

One of the most important parts of the tank setup is the substrate. The substrate will affect the look and feel of your fish tank. 

Each type of substrate has its own advantages and disadvantages. However, bettas don’t have a preference for one type of substrate over another, so you can mix and match.

Secondly, bettas need light to survive. They feed on plant roots and should be fed a varied diet daily. For this reason, it is important to choose a tank that has a light above the tank. 

A bright light will help you monitor your fish’s behavior and spot any potential problems.

Bettas are also easy to care for. They require little maintenance and are popular pets. They are also very playful and curious. They can even learn tricks. 

They can also recognize their owners. They can be extremely entertaining and can get you hooked on the hobby!


Danios are lively and hardy minnows. Their vibrant colors are easy to notice, and you can tell if your danios are stressed by their behaviors.

When a danio is stressed, it will seem skittish and disinterested in the food in its tank. It may also appear to be gasping and breathing heavily.

Danios are schooling fish that can reach lengths of 5 inches. They are fairly hardy, and they can tolerate a wide range of water conditions. While they can be boisterous and can cause harm to other fish in an aquarium, they rarely bite or injure other aquarium inhabitants.

This is due to the selective breeding that has produced these fish. The Danio family also includes white cloud mountain minnows, which are closely related.

If you have a tank with a minimum of 10 gallons of water, you can introduce danios to it. This species is easy to care for, but they are best kept in groups of five or more.

If you don’t have room for a school, they may get stressed and show aggressive behavior. Also, they prefer cooler temperatures.


Guppies are very colorful and are hardy fish that can live for weeks without eating. However, they must be fed a mixture of plant-based foods as well as meat-based foods. Some freshwater fish are also just as colorful as saltwater fish. 

Freshwater fish are beautiful and deserve to be treated with the love and care they deserve. Learn as much as you can about the species before making a decision. This is important especially when you’re the only one who wants a pet, and your partner doesn’t. This way you can convince your partner more about caring this type of fish.

Guppies are easy to care for and come in many different colors. However, be sure to separate males from females. 

Also, guppies breed very quickly, so it’s best to choose a pair rather than a single male and female. They are also very colorful and have interesting personalities.


Swordtails are peaceful and sociable fish that thrive in small groups. 

They are not as demanding as other types of freshwater fish, but they do require special care. Swordtails should be fed a clean, dry diet at least twice a week, and their water should be kept at a stable 80 degrees Fahrenheit. The water should also be kept as clear as possible.

Swordtails can survive in a 10-gallon aquarium, but they prefer a larger tank. Their natural habitat is a densely vegetated, moderately hard stream. 


They should be kept in a tank of at least 15 gallons for one fish and up to five gallons for each additional fish. Swordtails thrive in biotope tanks that replicate their natural habitat.

A swordtail aquarium should be at least 29 gallons (132 liters). This minimum size is sufficient if you are not planning to breed swordtails. 

Female swordtails will quickly produce fry, so if you plan on breeding them, you will want a larger tank.


Cichlids are a great choice for a freshwater aquarium and are available in a range of colors. 

These fish are known for their protective behavior towards their fry and can even breed in a home aquarium. Their native habitats are the lakes and rivers of South America, particularly the Amazon River basin. The water in these lakes is acidic, soft, and brown.

Cichlids come in several varieties, each with its own personality. Electric yellow cichlids, for example, are notably less aggressive than their relatives. 

They grow to around three inches long and have black fin tips. Peacock cichlids, which range from tan to silvery blue, are moderately aggressive. They are also bottom feeders.

Cichlids are an easy fish to care for. Cichlids produce a lot of waste, so a good canister-style filter will help keep the water clean. Choose a metal heater over a glass one, as cichlids like to move rocks and can damage glass heaters. 

The substrate for your cichlid tank should be made of pebbles or gravel. Avoid fine gravel, as it can be swallowed by larger cichlids.

Aside from being an attractive fish for your first aquarium, cichlids also require a stable temperature of between 24 and 26 degrees Fahrenheit. 

Because they can’t produce their own body heat, you should make sure your aquarium heater is thermostat-controlled to prevent the temperature from being too high or too low. In addition, you should always use Aqueon Water Conditioner to keep the water conditioned.


There are many reasons to choose freshwater fish as the main inhabitants of your new aquarium. For a start, they’re inexpensive and easy to care for. 

They’re also usually omnivorous, which means you can feed them any kind of food. This makes them a great choice for a beginner who’s new to fish. Freshwater fish are also easier to take care of than their saltwater counterparts. 

They are also more tolerant of mistakes and are easier to maintain. Plus, they’re colorful and unique. They also make a beautiful and unique addition to any aquarium. Once you’ve chosen the right type of fish for your aquarium, you’ll likely find yourself hooked.
