29 Aquarium Ideas For Your Betta Fish

Although your betta fish is beautiful and should take center stage, it needs more than just a vase or bowl with a sprinkling of gravel to be happy and thrive.

So, in this article, we take a look at 31 beautiful betta tanks that your betta fish will love. Plus, a quick refresher on the basic needs of a betta fish in order for your fish friend to have a long and healthy life.


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

You can read a complete and detailed article on betta fish care at this link. In the meantime, here’s a quick guide.


You should provide your fish with a tank that is at least five gallons in capacity.

Wild bettas establish territories of up to three square feet, so a small bowl or jar isn’t roomy enough.


A betta tank should have a lid or at least a sliding lid.

In their natural environment, during droughts or dry spells, bettas will jump from puddle to puddle in search of food, a mate, or new territory. If your tank doesn’t have a cover, your fighter fish may jump right out of your tank, just because they can!

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


Bettas live primarily in the upper area of ​​the water column and feed at the surface. In the wild, betta fish feed on insects and insect larvae that land on the surface of the water. Look closely at your betta and you will see that its mouth is upturned and full of small white teeth. That allows 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 your fish can breathe air through a specially adapted respiratory organ. Wild bettas live in stagnant or slow-moving water where oxygen levels can be low. The ability to breathe air allows fish to survive in harsh conditions. Captive bettas also need to come to the surface of the water periodically to take deep breaths.

Additionally, ornamental betta splendens have lush, flowing fins, which look spectacular but are a distinct handicap for the fish when it comes to swimming to the surface to feed and breathe.

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


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

Bettas are not strong swimmers, so the movement of the water in the tank must be smooth. If necessary, dampen filter flow with plants or decorations.

The pH level of the water should be between 6.5 and 8.0.

You will need to do a 30% partial water change each week and use a water testing kit to ensure parameters are consistent and correct.


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

Bettas are very susceptible to temperature shock, which occurs if the temperature drops below 75° Fahrenheit for extended periods of time or drops below 69° Fahrenheit. Temperature shock can kill bettas, so be sure to purchase a heater for your tank.


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

So your betta fish needs lighting in its tank. LED lights are the best option. The LEDs are long lasting and produce a very bright light that is perfect for bringing out the bright colors of your betta fish.


The substrate is the medium that covers the bottom of the tank. 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, easing the load on your biological filter and helping to keep your tank environment healthy.

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

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


Betta fish are curious and nosy fish that like to have a lot going on in their tank, keeping them active and keeping them from getting bored.

Fill your betta fish tank with plenty of caves, floating hollow logs, betta fish toys, and natural driftwood to provide hiding spots and shady spots where your betta fish can take a nap.

In the wild, the betta fish’s environment is full of vegetation. The fish like to hide among the plants and use them to rest as well. Live plants in your betta’s tank help oxygenate the water and provide a place for beneficial bacteria, which kill harmful bacteria in the water.

If you prefer not to use live plants, use silk plants instead. I do not recommend using plastic plants as they can have hard, sharp edges that can snag on the tail and flowing fins of your fish.


As a general rule of thumb, I think it’s best to avoid keeping betta fish with species that are pliers, such as barbs, which could harass and stress the betta fish. Remember that bettas are very territorial, so choose mates that live primarily at the bottom of the tank, like Corydoras catfish, or in the middle of the water column.

Bettas are members of the same family of fish as gouramis, and small varieties of that species generally work well as tankmates for betta fish. Snails and shrimp also make good tank mates and help keep the environment clean by eating algae and cleaning debris from the substrate.

Betta fish breed easily, and you can brighten a male betta’s day by adding a sorority of females to his tank. Watching the male betta fish build a bubble nest and then watch the spawning process of these lovely fish is mesmerizing!
