This owner has set up a tank for a betta sorority, using various colored plastic plants and bi-colored gravel substrate. As females lack the flashy finnage and color of the male betta fish, the colorful foliage adds to the effect, rather than detracting from the fish.

Betta Tank Quick Setup Guide

 Two betta fish put inside on a separate tanks.

Contrary to the popular urban myth, bettas are not happy living in jars or vases. They need much more than that to thrive!

You can read a full, in-depth article on betta fish care at this link. In the meantime, here’s a quick guide.

Tank Size

You should provide your fish with a tank of at least five gallons capacity.

Wild bettas establish territories of up to three square feet, so a tiny bowl or jar is nowhere near spacious enough.

Tank lid

A betta tank should have a lid or at least a cover slide.

In their natural environment, during droughts or dry spells, bettas jump from puddle to puddle in search of food, mates, or new territory. If your tank doesn’t have a covering, you may find that your feisty fish leaps right out of his tank, simply because he can!

When filling the tank, be sure to leave at least two inches of space between the water and the lid so that your betta can reach the surface easily.

A long or tall tank?

Bettas live primarily in the upper area of the water column and are surface feeders. In nature, betta fish feed on insects and insect larvae that land on the water surface. Look closely at your betta, and you’ll see that his mouth is upturned and filled with tiny white teeth. That enables the fish to grab prey from the surface of the water and prevent it from escaping.

Betta fish are anabantoids or labyrinth breathers. That means that your fish can breathe air through a specially adapted respiratory organ. Wild bettas live in slow-moving or stagnant water where oxygen levels can be poor. The ability to breathe air enables the fish to survive in challenging conditions. Captive bettas also need access to the water surface periodically to take gulps of air.

Also, ornamental betta splendens have luxuriant, flowing finnage, which looks spectacular but is a distinct handicap for the fish when it comes to swimming up to the surface to feed and breathe.

So, for those reasons, you should choose a tank that is longer than it is deep.

Water Quality

Dirty water stresses the fish, leaving him vulnerable to disease and even causing death. So, your betta tank should have a filtration system to remove ammonia and nitrates from the water.

Bettas are not strong swimmers, so the water movement in the tank should be gentle. If necessary, buffer the filter flow with plants or decorations.

The water pH level should be between 6.5 and 8.0.

You’ll need to carry out a 30% partial water change each week and use a water testing kit to ensure that the parameters are consistent and correct.

Water Temperature

The water temperature typically should be in between 75° and 86° in your tropical betta tank and ideally at a constant 78° to 80° Fahrenheit.

Bettas are highly susceptible to temperature shock, which occurs if the temperature falls below 75° Fahrenheit for long periods or drops below 69° Fahrenheit. Temperature shock can kill bettas, so be sure to buy a heater for your fish tank.


In the wild environment, betta fish live in shallow water, so they can see when it’s night and day. If your betta can’t see whether it’s day or night, he won’t know when to eat or sleep, which may stress your fish.

So, your betta fish needs lighting in his tank. LED lights are the best option. LEDs are long-lasting and produce a very bright light that’s perfect for highlighting your betta’s brilliant colors.

The substrate is the medium that covers the tank bottom. You can use fine gravel, sand, or aquarium soil.

A substrate is important, as it provides a large space in which “helpful” bacteria can grow and proliferate, relieving the load on your biological filter and helping to keep the tank environment healthy.

Bettas love plants and ornaments to hide in and explore, and a substrate helps to keep everything in place.

Finally, the right choice of colored substrate can help to show off your beautiful betta’s colors to maximum effect. For example, a crimson veiltail betta looks spectacular against a black substrate.

Decorations and planting

Betta fish are curious, nosy fish that like to have plenty to do in their tank, keeping them active and preventing boredom from setting in.

Populate your betta tank with lots of caves, floating hollow logs, betta fish toys, and natural driftwood to provide hiding places and shady sites where your betta can take a nap.

In nature, the betta’s environment is thick with vegetation. The fish like to hide among the plants and use them for resting too. Live plants in your betta’s tank help to oxygenate the water and provide a place for beneficial bacteria, which remove harmful bacteria from the water.

If you prefer not to use live plants, use silk ones instead. I don’t recommend using plastic plants, as they can have hard, sharp edges that may snag on your fish’s flowing tail and fins.

As a general rule of thumb, I find it best to avoid keeping bettas with species that are fin-nippers, such as barbs, which could harass and stress the betta. Remember that bettas are highly territorial, so choose companions that live mainly on the bottom of the tank, such as Corydoras catfish, or in the middle of the water column.

Bettas are members of the same family of fishes as Gouramis, and small varieties of that species usually do well as tankmates for betta fish. Snails and shrimp are also good betta tankmates, and they help to keep the environment clean by eating algae and tidying up detritus from the substrate.

Betta fish spawn readily, and you can brighten up a male betta’s day by adding a sorority of females to his tank. Watching the male betta constructing a bubble nest and then observing the spawning process of these charming fish is fascinating!

In Conclusion

When choosing a good tank for your betta fish, there are several elements to consider:

  • The tank must be large enough.
  • You should include a suitable substrate to anchor plants and provide a large surface area where beneficial bacteria can grow.
  • Toys and decorations are important to keep your fish entertained and prevent boredom.
  • You should include structures such as caves and hollow logs in which your fish can sleep and hide.
  • The environment should contain plenty of plants to oxygenate the water and provide places for your betta to explore.
