How To Choose The Best Betta Tank

Any fish are super sensitive you, therefore, need to consider a few factors before you buy a betta tank. Although they're all functional you need to do a trial and error before you pick one.


The size of your betta tank speaks volumes on how many fish you need. It also determines the amount of space available in your house or office. There are different sizes of betta tanks ranging from 5-gallon to 1-gallon.

The bigger the size, the more space it will take on your countertop and the fish will have enough space to swim in. There are however those tanks that can fit in the smallest of spaces as they are circular or oval. Before you settle on one, ensure that it will fit on the space you have available.

Material Of The Tank

The best betta tanks are made from glass or acrylic. This is a personal choice for you as you decide one that you can afford and one that will cater for your needs.

Tanks made from glass are the most common ones. They are transparent, so they make viewing of your fish interesting. You can also notice when the tank is dirty prompting for cleaning. Glass is also scratch resistant making cleaning a breeze

Acrylic tanks are slowly finding their feet in the market. The advantage of these types of tanks is that they can be of different shapes and sizes. Most tanks that are either cylindrical or oval are made from acrylic. They, however, scratch easily when cleaning.


The weight of the tank is directly related to the material used to make the tanks. Tanks made from glass are heavier compared to those made from acrylic. You also need to factor in the weight of the tank before you put water inside. As this will determine its ease of movement. If your tank is heavy, you need to have a very sturdy base to put it on.

Otherwise, it will break easily. Lighter tanks, on the other hand, are easier to move around with or without water in them.


Lighting is important in betta tanks as they make the fish feel like they're under the sea. It also adds on to the aesthetic value of your office or home. Betta fish tanks come in a variety of decorations that if illuminate exuberate beauty. You also get to show off your fish to your friends or your clients.

The best betta tanks in the market come with LED lights which assist in illumination. These LED lights have switches or remote controlled switches to turn them on. Some tanks come with different lighting settings for daytime and nighttime. Most of the tanks are rechargeable, so you won't have to worry about the lights going off.


This is the most important factor to consider before you buy a betta fish tank. Fish excrete ammonia which can be very dangerous to the fish and also to you. You need a tank that is easy to maintain. One that won't take a lot of time and money to keep clean.

The best betta tanks come with their filtration systems that are responsible for cleaning the water in the tank. They also come with plants that use the chemicals fish excrete as manure for their growth. This helps in keeping the ecosystem of the tank clean and steady. Even though the best betta tanks are self-cleaning, you need to change the water, or a have a mechanism that does and also clean the interior of the tank.

Final Verdict

The best way to teach your kid responsibility is by getting them a pet. If they're first timers, I'd recommend fish. The betta tanks are easy to maintain and look after. For this to be possible, you need a fish tank.

I'd recommend any of the above discussed they're the best betta tanks in the market. They're also small and efficient if you're short on space. Ditch the excuses and get yourself a betta tank.
