What You Need for a Great Betta Fish Tank

We selected the aquariums we introduced to you carefully and based on over 20 hours of research.

We’ve taken into account everything that’s necessary for you to set up a fantastic home for your betta darling in which they can be happy and healthy.

When choosing the products on our list, we took into consideration the most important factors for a great betta fish tank:

  • the right size of the aquarium
  • suitable filter for betta fish
  • suitable lid for betta fish

A heater is not included in all the aquariums on our list but it can be added easily if it’s needed.

Size Matters When It Comes to a Betta Fish Tank

It’s a myth that bettas can live a happy life in a tiny bowl. They can certainly survive in one for a short time but it’s absolutely not a suitable long-term home for your finny friend.

As a responsible fish parent, you should keep your betta in a fish tank that has a capacity of at least 5 gallons. When their aquatic home has an ideal size then your betta will be able to thrive and engage in natural behaviors like swimming, hiding, and playing.

A Betta Fish Tank Needs a Filter

We’d like to bust another myth that bettas don’t need to be in clean water and thus don’t need a filtered fish tank. This is not true!

The natural habitat of betta fish is the standing waters and puddles of rice paddies and canals in Southeast Asia. Bettas can survive in small, oxygen-deprived water spaces. But that doesn’t mean that an unclean environment is a suitable long-term home for your betta.

Betta fish tanks need to have a good filter with gentle water flow. As a betta parent, you also have to clean the aquarium and make water changes on a regular basis.

A Betta Fish Tank Should Have a Lid

Talking about unsuitable environments, in nature, bettas actually ditch their home when it doesn’t provide them with good living conditions. They do that by jumping into another water source.

Yes, betta fish can jump!

They have the ability to jump a few inches to move into a more suitable living environment. This is why it’s ideal to get a betta fish tank with a lid.

It’s not an absolute must and bettas can also be kept in open fish tanks. But with an open tank, there’s the risk of your betta jumping out of their tank.

A lid provides the necessary security, keeps unwanted visitors out and betta fish safely inside their home.

Betta Fish Need to Be Warm

Bettas are tropical fish that thrive in warm temperature. The ideal temperature of their watery home should be around 75 – 82°F (24 – 28°C).

That’s why you also need to get a heater for your betta fish tank unless it’s placed in a room with a constantly high temperature.
