Fish Tank Equipment

A fish tank is a great way to keep your pets happy and healthy. However, to make sure that your fish tank is set up correctly and that the water is clean, you will need some fish tank equipment. Here’s a closer look at some of the most important items:


If you’re considering adding a filter to your fish tank, there are a few things to keep in mind. The type of filter, the tank size, and how often it should be cleaned all depend on the fish species and the environment you’re trying to create.

A filter is essential for keeping your tank clean and healthy, especially for tanks this size, as toxins tend to build up quicker in small volumes of water.

Look for a filter that can handle high and low water levels and remove harmful chemicals and bacteria.


Keeping a tropical fish such as bettas requires keeping a heater in your tank. Heaters can provide the perfect temperature for your fish which ideally ranges from 75-80°F.

Some have timers, so you know when to change the heat, while others are simply on/off switches. They also come in various sizes and styles to fit any need or budget, so make sure to choose one that is best for a 5-gallon tank.

Lighting system

The best lighting system for a betta fish tank mimics the natural light of day.

Most people use fluorescent tubes to create artificial light. This type of lighting will work, but it’s not as good as sunlight because it doesn’t provide the same spectrum of colors and can cause algae growth inside glass walls.

These problems can be solved by using an incandescent bulb or a LED bulb with blue lights, which will mimic natural daylight and won’t produce heat as other bulbs do.

Substrate and decors

Betta fish are low maintenance but need an aquarium with clear sides to see their surroundings, rocks, and plants for hiding places, and some driftwood to provide them with extra oxygen.

These fish do not require any special substrates, but it is recommended that you use a sand substrate to prevent ich from developing.

Cleaning tools

Cleaning tools are very important to keep your betta’s environment clean and safe. Some tools that can be found in a cleaning kit include scrubbers, nets, buckets, and scrapers.

Scrubbers help remove algae from rocks and other surfaces, while a fish net can scoop up debris or fish waste from the bottom of the tank without disturbing any plants or decorations.

Some other popular items include algae scrapers for removing unsightly green film on glass surfaces, tweezers for reaching into tight spaces to remove dirt and scouring pads for scrubbing hard-to-reach places like corners.

Air pump

Aquarium air pumps are an essential part of any fish tank, and for good reason. They help to oxygenate and circulate water to keep your fish alive.

Before getting an air pump, remember to consider the type of filter your tank uses, the size of your tank, and the power requirements.

Test kits

Aquarium test kits can be used to check the water quality in an aquarium. These kits typically come with instructions on how to use them and what they measure and how often they should be checked.

The tests may include measures for pH levels, ammonia levels, nitrite, and nitrate levels. Test results will vary depending on which type of test is being taken. Some tests may need to be done over time until enough data is collected for an accurate reading, while others may only require one measurement per week or month.

In addition, these tests can tell you if your tank needs more cleaning or maintenance and can be easily bought at your local pet stores or online.

FAQs About Fish Tanks

When it comes to buying a fish tank, there are a lot of questions that people have. Here are some of the most common questions and answers you may want to know:

Should I get a fish tank kit or just the tank only?

This is a question that many people are faced with. The answer depends on what you plan to do with the fish tank and how much money you want to spend.

If you’re going for an elaborate setup and have some extra cash to spare, go ahead and buy the kit. You’ll save time trying to find all the pieces separately, which can be difficult if it’s your first time setting up a fish tank.

However, if you don’t mind hunting around for everything individually, then buying the tank only would be the preferred choice. The challenge of customizing your tank might be daunting but could be extremely fun.

What is the dimension of a 5-gallon fish tank?

A typical 5-gallon aquarium is 16 × 8 × 10 inches, weighing 7 pounds. However, many of these aquariums do not have these dimensions, especially those unique and design-based tanks.

What kind of fish should I get for a 5-gallon tank?

When choosing the right fish for your 5-gallon tank, there are a few things to keep in mind. The type of fish you choose will depend on the size of your tank, the kind of water you have, and your personal preferences.  

Here are some types of fish that typically thrive in smaller tanks:

  • betta fish
  • goldfish
  • corydoras catfish
  • dwarf gouramis
  • mollies
  • guppies

How many fish can I have in a 5-gallon tank?

If you’re thinking of keeping two bettas in a 5-gallon tank, you may want to abandon that thought. Bettas are more aggressive towards each other, especially males, so it would be best not to take that risk.

The general rule for fish keeping is one inch of fish per one gallon of water. This means you can stock up to 4-6 small fish in a 5-gallon fish tank. However, since bettas are territorial and aggressive, it is best to keep only a few fish – and a friendly one – to be housed with a betta.

Is a 5-gallon fish tank good for a betta fish?

A common misconception about bettas is that they can live in tight and small spaces such as fish bowls. Although they can survive in this environment, if you have the means to get a larger tank, then please do so.

A five-gallon fish tank is generally the smallest size available for bettas, so it’s important to be sure that the tank has enough space for them to swim around. Bettas thrive more when they have adequate space to explore aside from having a clean and well-maintained fish tank.

What are the advantages of 5-gallon fish tanks?

There are a variety of reasons to choose a 5-gallon fish tank.

  • First, they’re ideal for beginner fish keepers.
  • Second, they’re popular among experienced hobbyists because of their low price and small size.
  • Third, they’re versatile – you can use them for freshwater or saltwater fish.
  • Fourth, they’re easy to clean and maintain.
  • Fifth, they make great starter tanks for kids who are interested in aquatics.
