Best Betta Fish Tank | 2022 Guide

If you’re fairly new to fish-keeping, a hardy betta is arguably one of the best choices of aquatic pet. Betta fish are dazzling to look at, with elaborate fin and tail shapes and a plethora of eye-catching colours. Their striking appearance more than makes up for the fact you can usually only house one betta per tank at any one time.

Because betta fish are best housed alone, you have more options available to you when it comes to picking out a suitable tank for them. A betta fish tank doesn’t need to be particularly large, while filters don’t need to be all that powerful as they will only be dealing with minimal impurities. However, if you want your betta of choice to thrive, there are some key things to keep an eye out for when selecting a new tank.

Tank Dimensions

Although betta fish can get by in a very small tank, you should ideally be looking for something with a capacity of 5 gallons or more. Although bettas can live quite happily in smaller tanks than this, more swimming space will encourage them to move around more, making for a more more attractive display. A larger tank size also means slight changes in ammonia and other chemical levels within aquarium water can be more easily corrected without your fish coming to any harm. If you have your heart set on a particular variety of betta, do some research into the environmental requirements of the desired breed to ensure you have a tank that is fit for purpose.

Filtration Systems

Although a single betta fish will produce far less waste than an aquarium made up of many individuals, their tank conditions still need to kept in check. Betta fish require oxygen-rich waters in order to thrive, so you’ll require a filter that can keep these levels in check. You also want to avoid disturbing your betta fish too much once their tank is established.

Although you’ll inevitably have to carry out regular water changes to maintain healthy tank conditions, your filter should be taking care of much of the hard work. One thing to consider when selecting a filter for your betta tank is the flow rate. Filters with particularly high flow rates can be problematic for betta fish. To avoid any issues, opt for a filter with a low or variable flow rate that can be easily adjusted.

Heater Elements

The majority of betta fish species originate from tropical climates. Therefore, tank water needs to remain fairly high at all times. Some tanks can remain warm by being exposed to regular LED lights, provided of course the tank is placed in a stable environment. However, even in these cases, you’ll need to regularly check the water temperature with a digital thermometer. If your betta fish tank is large enough to house one, you should definitely invest in a tank heater to ensure water conditions remain optimal at all times.

LED Lighting

If you want to show your betta fish off, you’ll probably want a tank that includes some form of LED lighting. Even the cheapest of betta tanks will usually include an LED array above the canopy, providing you with a white or blue light source. The best tanks will include the option to alternate between different colour hues. Some may even include automated lighting patterns to provide unique displays. If you are purchasing a tank with a particularly powerful LED array, make sure it comes with a timer function. This will prevent your lights from remaining on indefinitely, which can cause some issues with water temperature.

The Verdict

Although betta fish are fairly easy to care for, there are a few key things to remember before rushing out to purchase a new pet and tank for them. Most importantly, you need to remember that bettas are an incredibly aggressive fish. Never pair male bettas together and avoid keeping female bettas together whenever possible. If you must keep multiple fish at any one time in the same tank, opt for an aquarium that includes separate pens that can be partitioned to avoid battling bettas.

Because you will almost certainly only be keeping one betta fish at any one time, you don’t need to opt for too large a tank. Even a very modest 1.5-gallon tank should prove sufficient for your bettas, although it’s also advisable that you opt for as large a tank as possible. If you’re excitedly planning some unique aquarium landscaping, you should definitely opt for a larger tank as you’ll have more freedom to incorporate bulkier ornaments and deeper substrate layers.

Finally, you’ll want to be weary of budget. Because the majority of betta tanks are on the small side, you’ll rarely find betta-friendly aquariums retailing for sky-high sums. However, always ensure that your tank comes with a few basic components so you can start using it straight away. Most betta tanks will include a filtration system and pump as standard. Unlike other tanks that house many fish and will need to keep on top of excessive amounts of waste, your betta tank filter will less heavily utilised. Therefore, you won’t need to worry too much about replacing the filter that comes with your tank with a separate model.
