When we think of Betta fishes, we picture a small fish that may not need that big of a tank. The misconception stems from both size and that of a male betta fish being very highly territorial and aggressive, making them an excellent choice to keep them alone in a small space such as vases or bowls.

The truth is that the betta fish requires more than just an adequate tank to live healthy and long lives. They need a container where they have space for swimming. The minimum size tank that a betta can easily thrive in would be a minimum of 5 gallons tank.

Buyer’s Guide: What to Consider When Choosing a Betta Tank

1) Tank size

In the wild, rice paddies and shallow streams are betta fish’s natural habitat. But that doesn’t mean that the betta fish can thrive in small spaces like vases and tiny bowls. If your space can only accommodate a small tank, a 5-gallon should be the minimum size tank that you should select. Bettas are great fish, and they deserve the best environment to thrive and be healthy.

2) Filter

A filter helps in ensuring that the water stays clean. It also saves the fish a lot of stress and hassle when there is a need to change the water when it gets dirty. Also, filters provide an oxygen-rich environment that is desired by betta fish. When selecting a betta tank, it’s best to get a tank with a filter.

3) Heater

Betta fish are tropical fish and live in water that maintains temperatures of 75-82°F. The heater will help maintain a stable temperature equal to that of their natural habitat to ensure that the tank water is at the correct temperature, it’s best to place the thermometer at the opposite end, farthest away from the heater.

4) Light

The installation of lights can help to bring out the colors in your fish, promote regular night and day patterns, and make it easy to spot any disease symptom. Most tanks come with a built-in lighting system and LED light is the best option.


Hopefully, now you have an idea of how to choose the perfect tank for your betta fish so that you may be able to offer a quality environment that will allow your fish to stay healthy and thrive.
