An aquarium is a beautiful addition in your home for you and children. For many, fish are preferred pets. By having fish, you’ll also get to enjoy an array of choices for aquariums. 

Building the best freshwater aquarium to have the best possible living environment for your fish is influenced by your preference as well as some important steps that you have to take.

Let’s take a look at how to build the best freshwater aquarium.

  1. Decide On Fish Type 

Before building your freshwater aquarium, you must decide on the type of fish that you want to buy. This is the first important step because the fish type and the number of fish will determine the type of tank, such as size, plants, and water make. 

Once you know the type of fish you’re preparing your home for, you can then prepare the tank.  

  1. Assemble Equipment 

When you’re ready to prepare the tank, make sure that you have the equipment ready for easy set-up. Depending on the tank that you have, you may need a thermometer, substrate, plants, power socket, freshwater, and an aquarium heater, which is important for heat regulation.

  1. Clean The Tank 

Introducing any fish into a tank that isn’t prepared properly creates a toxic space for your fish. Thus, you have to thoroughly clean the tank and get rid of any dust particles, molds, or stains.

Also, avoid any soap as these will introduce chemicals into the aquarium. A wet cloth would suffice when cleaning your tank.  

  1. Tank Inspection

Once the tank is clear and clean, you can place your clean hand inside it to feel for any cracks and openings. You have to feel for these as some are not visible to the naked eye. 

Filling up a tank with cracks will worsen it, opening the tank for some leaking. If you notice that the tank has cracks or openings, you must consider replacing it for the best freshwater aquarium.

  1. Tank Placement 

Once you’re certain that your tank is in the best condition possible for the fish, you can place the tank where it’s suitable in your home. The location you choose must be a permanent position as you won’t be able to shift the tank around once it’s full of water. 

To protect the fish, you must place the tank near a power socket, and away from any direct sunlight and heat. 

  1. Add Substrate

Substrates serve different purposes such as adding a healthy environment for the fish or simply for aesthetic reasons. You can choose the type of substrate you wish to include, such as an under-sea theme for the children or a beach toned substrate. While you enjoy the appearance of the tank, the fish will also appreciate the natural habitat, particularly those that enjoy digging holes. 

To avoid toxins, make sure that any substances or particles you place in the tank are clean.

  1. Tank Cycling 

Cycling is the process of building up bacteria essential that’s for the fish’s health. The cycling process starts by adding ammonia into your tank. Ammonia and nitrate levels are meant to rise and then slowly start to fall. It takes about six weeks for an aquarium to attain the proper number of beneficial bacteria to support the fish. During those six weeks, the water in the tank should be changed weekly.

To determine the levels, you need to do a weekly test on the water in your tank. When the ammonia and nitrate levels reach 0, you can then introduce the fish to their new habitat.

  1. Fish Addition

It’s encouraged to gradually add fish into your tank, preferably one or two at a time. 

To assist with the process of acclimatization for the fish, you should gradually add water from your aquarium into the fish bag. This ensures that the fish doesn’t get stressed out by the pH or the temperature of its new home. 

  1. Maintenance 

Now that you have your aquarium set up, you have to maintain both the habitat and the fish. To avoid the build-up of dirt and monitor any foreign objects that may be in the tank, you must clean the fish tank. Keep in mind that if you have children, they might be tempted to share their toys with the fish. 

Feed your fish only once a day as feeding them too often will upset the environment in the aquarium. It’s also important that you don’t continuously add fish to the aquarium. Too many fish will increase the ammonia in the tank, which may kill your fish.


Adding fish into your household requires research, procedure, and consistency. It takes weeks to prepare a healthy habitat for your fish. 

First, you need to decide on the type and number of fish you wish to include in your aquarium. Then, clean, inspect and place your tank on the desired location, add substrate, cycle the tank, add your fish, and constantly maintain the aquarium. 

The livelihood of the fish depends on these steps as short-cuts may result in the death of fish.
