Betta fish tanks are tanks designed specifically to meet the needs of this unique fish. Betta fish, otherwise known as Siamese fighting fish, are small-but-vibrant freshwater, tropical fish. They can make great pets for those who enjoy taking care of aquatic life. This fiercely independent fish prefers to swim alone, but some females may get along in one tank if there is a sufficient amount of space for them to each have hiding spots. Therefore, the type of tank you choose for your Betta is pretty important.

Just like all other types of pets, you want to provide the best for your fish. We asked our veterinarian advisor, Dr. Jamie Whittenburg, to review Betta fish tanks to help find the best ones available for your Betta fish. She chose the Fluval SPEC Freshwater Aquarium Kit, with LED Lighting and 3-Stage Filtration because the 5-gallon tank provides adequate room for a single Betta fish. It’s also small enough to display on your desk or table. Read how she chose the top 5.

Who Should Buy a Betta Fish Tank

  • Betta fish keepers – If you’re interested in taking care of Betta fish or already have one, consider investing in a Betta fish tank made to the specifications of a Betta’s natural habitat to keep your fish happy and healthy.1
  • Apartment dwellers – If you’re short on space but are looking for a pet, consider getting a Betta fish. In which case, you’ll need a Betta fish tank as well to be sure your fish is in the right environment.

Who Should Not Buy a Betta Fish Tank

  • Those who don’t have Betta fish – If you have fish that are not Betta fish, get a tank that is better suited to the type of pet fish you do have. Not all aquatic life like the same size or shape tank.[efn_notes]Hartz. Different Fish Types, Their Aquariums and Care. Hartz.com. Accessed January 13, 2022.[/efn_note]
  • Those who are unable to care for a pet – Betta fish are wonderful low-maintenance pets but do have specific requirements to keep them healthy, and still need regular care.2

Research Tips (from a Veterinarian)

The aquarium you choose for your pet fish will be their home and entire world. A water filter is a must for every fish aquarium, which helps keep the water clean and reduces the risk of issues with ammonia. Depending on where the fish are kept, a heater is often crucial as well. Here are some more tips and best practices when looking for a Betta fish tank.

  1. Talk with your friends, neighbors, and veterinarian for Betta fish tank recommendations – Ask around to other fish keepers about what they do or don’t like about their tanks. Also check the display of the aquarium setup you’re interested in, either in-store or via pictures, so that you can get an accurate impression of the size and appearance of the tank.
  2. Consider the ease of cleaning the tank – Fish tanks need to be cleaned frequently to keep your fish healthy.3 A fish tank that is difficult to clean may not get cleaned often enough.
  3. Look for fish tanks made with solid construction and quality materials – Some fish owners prefer the look and clarity of glass. Others, such as those with small children at home, may prefer plastic. In my experience, glass aquariums tend to clean more easily. Glass also stays clear long-term, making it more enjoyable to watch your Betta fish. Plastic may become scratched or cloudy. However, over time, leaks are more common with glass aquariums.
  4. Select a Betta fish aquarium that comes with a top or covering to ensure the safety of your fish – Some fish jump out of their aquariums, so it’s a good idea to choose a tank with a lid.4 This will also keep cats and other curious creatures from reaching into the aquarium.
  5. Consider the size and shape of the Betta fish tank – Choose an aquarium that’s spacious enough to give your Betta fish adequate room to swim around, and also holds enough clean water. Betta fish, especially males, are very territorial and shouldn’t be kept with other Betta fish.5 It is possible, though, to keep more than one female Betta in a tank, if necessary.6 Keep in mind where you want to put the fish tank when selecting a size.

How Much Do They Cost?

$15 to $125

Betta fish tanks cost roughly $15 to $125 depending on the type of tank you purchase. From small to large gallon tanks, you have the option of choosing from a variety of different styles. Less expensive fish tanks usually offer just the basic aquarium, while more expensive tanks may include a kit of aquatic accessories. Plastic fish tanks also tend to be cheaper than glass tanks. For instance, the Tetra Aquarium Kit and the Fluval SPEC Freshwater Aquarium Kit are both 5-gallon tanks, but the Tetra, which is plastic, costs less than the Fluval, which is glass.

Frequently Asked Questions

What shape tank do Betta fish like?

Betta fish prefer an aquarium that best mimics their natural habitat, which is often an expansive amount of territory. Long tanks, as opposed to round tanks, are more apt to make your Betta happy. 7

Do Bettas like deep tanks?

Betta fish grow up in shallow water and often poke through the surface to breathe the oxygen. They gravitate toward swimming back and forth, not up and down. 8 Therefore, deep tanks don’t allow your Betta sufficient space for swimming.

Do Betta fish get lonely?

Though Betta fish are notoriously aggressive and are known to not get along with other Betta fish, they still need an interactive environment. Betta need spaces to hide and also do well with plants and other decorations. Safe tank mates include mystery snails and ghost shrimp. 9

Do Bettas need a bubbler?

Betta fish don’t necessarily need a bubbler in their tank. 10 They naturally swim to the surface for a breath of oxygen. Don’t fill your fish tank too close to the top so your fish can get some air.
