3. Koller Panaview 5 Gallon Aquarium 

The Koller Panaview 5 Gallon Tank is a nice option sporting various LED color selections that can make your fish look brilliant when illuminated.

The filtration system does a wonderful job of cleaning and purifying the aquarium at a rate of 45 gallons an hour. This will eliminate all organic pollutants like heavy metals and toxic gases and include easy-to-find Tetra Whisper 5 filter cartridges. 

The plastic material is impact-resistant, so you can get the great look of a glass aquarium without worrying about shattering. Moreover, it is an all-in-one product, making it easier to set up and take down to move, change rooms, or do thorough cleaning.

This glass aquarium contains a remote control, enabling you to select different colors and special effects to improve the aesthetic of the fish tank. 

The water quality of your aquarium will be properly maintained, thanks to its robust three-stage filtration. The media is mechanical, biological, and chemical. Noticeably, the filtration system stays hidden in the back of the aquarium, making it look more delicate. 

The curved front of this tank makes it look bigger than it is, and can act as a beautiful decoration for your bedroom or a home office. The hole on the top of the aquarium can get you easier feeding. 

The tank offers everything necessary to get started to keep betta fish, except for a heater. 

It is a good idea to fill the back empty filter area with several filter sponges as it can help slow down the water flow and make your betta fish more comfortable.

6. Fluval Spec V Aquarium Kit (5-gallon)

The Fluval Spec V Aquarium Kit is the go-to choice when it comes to the 5-gallon aquarium for betta fish. Constructed from etched glass, you will get a contemporary-looking fish tank that’s perfect for small areas.

In addition, it is packed with all the necessary media: a porous foam block with a handle, BioMax rings, and activated carbon. Plus, the three-stage filtration works quietly and effectively, making it simpler to clean the aquarium. 

The circulation pump might be too powerful for you bettas, but you can adjust the output nozzle with ease. What’s more, buying a pre-filter sponge can help calm the water jet down efficiently.

The Tetra Half Moon is not elaborate, but it’s a rugged, utilitarian aquarium that can get the job done at a reasonable price. 

The back of the aquarium is flat, enabling you to snug it up against the wall. It also only contains 1.1 gallons of water, so you don’t need to spend much time filling it up. However, the space is only enough for one fish. 

It’s possible for you to adjust the LED to illuminate the aquarium from above or below. That brings you versatility and makes it easier to watch your fish. This betta fish tank requires three AA batteries, but you can charge it with a micro-USB cable.

What to Consider When Buying A Betta Fish Tank?

Betta Fish Tank Size

You need to have a least 5 gallons for the aquarium to be properly sized. Bowls or cheaply-made tanks are not a good idea.

Most people assume that as bettas inhabit rice paddies, they can survive well in small aquariums. Nevertheless, rice paddies are larger than we think and offer the fish a lot of space to swim and grow.

Moreover, a tiny bowl results in less than expected water quality. Ammonia can and will rise to unsafe levels in that bowl. By raising your betta in a 5-gallon or bigger aquarium, they will have more space to play and swim around.

Even some types of betta, like the Crowntail, require you to keep in bigger size tanks. Ensure you conduct research on your betta species so you know just what to purchase.

Dimensions of The Aquarium

Tank size in gallons is crucial as it brings your fish space to thrive. However, ensure you measure the space you will put your tank in.

You would not want to purchase a tank, unbox it and find that it doesn’t fit in your living space.

Keep in mind that betta fish tanks cannot just go anywhere in the house. Bettas will not grow in your dark, cold garage, for instance. Moreover, it is not properly sanitary to place a fish tank in the kitchen.

Aquarium size will affect pricing. Every individual’s budget is different, and buying a larger aquarium will lead to a larger bill when to reach the checkout line.

Your purpose is to position the tank in a spot that is easily seen but not so busy that the noise bothers the fish. For example, the living room might not be the best location for a fish tank, but your bedroom is a suitable one.

What’s more, you need to keep the aquarium away from ventilation systems and windows. Drafts blowing on the aquarium might affect its temperature and sunlight can promote algae growth.

The Filtration System

Some presume that as bettas live in shallow waters, it’s fine for them to live in dirty environments. This is a big misconception: the water is clean, thanks to the plants and other members of the ecosystem.

Bettas have the excellent ability to adapt to new bodies of water. They can hop from puddle to puddle when they find out new places. Creating a clean habitat is essential to these fish. Even though they can survive in a small puddle, this is not suggested as they cannot grow. And they won’t survive for a long time.

Hence, a filter can help mitigate the buildup of bacteria and dirt in your aquarium. If you don’t have a filter, you have to perform partial water changes every single day.

Plus, you may add a pre-filter to decrease the flow of water on the filter’s outlet because this will make your betta fish happier.

Heaters

Betta fish come from Cambodia, where the temperatures are very high. Your aquarium should always stay at 76 degrees Fahrenheit or above.

If you don’t live in a place where the temperature is always higher than 76 degrees Fahrenheit, you will need a heater. Though 76 degrees F is the minimum, 78 degrees F is perfect. Besides, you should ensure the temperature never rise above 82 degrees F. A high-quality heater will automatically turn off when the water is too hot.

Make sure you include a thermometer, so you can closely track the temperature and keep it comfortable for your fish.

Provided Accessories

Some betta fish tanks provide accessories, such as gravel, heaters, decorations, and other useful items. Meanwhile, some do not come with necessary accessories. Some aquarists want to purchase all their items separately and others want an all-in-one solution. It’s about personal preference because you might already have some items at home.

Remember to read what is packed with the tank, so you can find out what you’re getting.
