Betta fish are among the most popular and beautiful tropical freshwater pet fish in the world. The long flowing fins, elaborate and flashy colors, and iridescent scale makes them more attractive and eye-catching.

I find them amazing as there are many different varieties of betta fish that you can find in almost every pet store. One of the reasons they’re so popular is that they come in various colors, patterns, and tail variations. 

Along with being beautiful, they’re cheap too and easier to be taken care of than many fishes, but that doesn’t mean they do not need special care. They need proper conditions to live in, too, and for that, you need an appropriate tank.

Because the lid is so close to the water’s surface, there is a lot of splashing onto the light, but the lights seem to be very well sealed, and there have been no issues. The lights are very bright at full intensity but can be dimmed.

The lid had very few cut-outs, and there is a gap in the cover along the length of the back where you could run cables and the airline. 

There are a couple of scuffs in the acrylic right along the front side, but it is strong. It’s also really nice that there is a separate cord for the LED lights, and not only that, but you can separate the lid and a few inches of cable from the rest of the cord.

There is a nice switch on the longer section of the cord for turning off the light without unplugging it. There is also a feeding hole that’s cut in the front of the lid that you can cover too, but it’s easy to open the top up so you can feed your bettas.

According to many reviews, the lights were too bright for the fishes, as they were hiding from it. This tank might not be suitable for big fishes, but it is perfect for putting small fishes like goldfish and bettas and suitable for shrimps.

Things To Consider Before Buying A Tank For Bettea Fish

Betta fishes are indeed popular and adorable. They are spunky, and they will become your favorite pet because of their bold and bright colors. Not only this, but they come at a low cost; hence, people worldwide are their fans.

Handling fish is not a child’s play as it’s a matter of handling the life of living organisms, and you don’t want your fish to struggle.

Bettas are often considered an easy starter fish by many people. Still, they are mostly unaware of the specialized requirements that are needed to keep your betta fish healthy, comfy, and survive without struggling. 

If you plan to decorate your kitchen or living room with a beautiful aquarium tank along with a betta fish in it, it is extremely necessary for you to buy the best-suited tank for your betta fish. 

But it is not that easy to find the best tank for betta fish, therefore, here are some important points that you should keep in mind when purchasing as you will need it for quite a long term and it will also be a home for your beloved pet.

Material of construction

It is extremely important to keep your eyes on the material from which your tank is made of. When talking about the construction of a fish tank for betta fish, avoid tanks that are made of plastic.

Plastic tanks have less durability and are easy to get scratches and visual distortions. Therefore you should tend more to tanks made up of acrylic, or a more appropriate choice could be glass. 

Acrylic tanks are lighter but can easily become scratched or discolored. On the other hand, glass tanks are stronger and more affordable. Your tank will never get yellow or fog and does not create as much visual distortion as plastic tanks.

Capacity of tank

You might always have seen betta fishes in small bowls and small tanks when you go to aquarium and fish shops, but that is not the correct way of keeping a betta when you plan to keep one at your home.

They should not be kept in bowls as they need space to swim around; therefore, Therefore they should ideally be in a five-gallon glass tank or more.

There are more chances of the water quality becoming toxic quicker in smaller spaces which can be dangerous to the betta fish. Hence, a little bigger tank allows the betta fish to do normal activity and have less buildup of toxins in their environment.

Use tanks with proper Filter

A tank without a filter is incomplete, especially if you buy it as a new home for your bettas. The filter plays a key role in the health of your tank and the aquatic lives living in it.

In case if you choose not to use a proper filter when keeping a betta, it definitely is a big responsibility as you will need to do more large water changes per week, so the water does not become toxic for the fish.

A filter is a much better option for you as well as for your betta as it will save so much of your cleaning time, and your betta stays in clean water and stays healthy. It also helps to aerate the water. 

The Right Temperature for Bettas

Keeping the proper temperature is a prior point when you keep a betta as a temperature lower than 74 degrees is too cold for your betta fish and room temperature water is normally 68 degrees.

Therefore, keeping the betta fish at normal room temperature may not be a good choice as it becomes too cold and prolonged periods in cold water shorten your fish’s life.

Not only this, but bettas stop eating in very cold waters and have less access to oxygen, making your fish drowsy and may also hover near the bottom of the tank trying to get warm.

Keeping the bowl or tank in a warmer location in the house may help, but it isn’t a perfect solution as it might keep your bettas warm in the daytime but not at night. It is more challenging when you live in cold climates.

So the best solution to this problem is to keep the fish in a heated aquarium, or you can also consider adding a heater to your fish tank. You can also put a mini-heater in your bowl, but it’s quite difficult to maintain the proper temperature in a bowl. 

Proper lighting 

You don’t need to give too bright or too intense lights as bettas don’t like such lights. Instead, the standard aquarium lights are perfect. 

Some tanks also have moonlighted or nightlights for nights that are mild and glow enough to keep your bettas calm without panicking and have rest. Now, this was about the lighting, but bettas also require darkness.

You should provide your Betta fish with an adequate amount of darkness so that they can sleep at night. They will need around twelve hours of darkness within a twenty-four-hour period to stay healthy.


There are so many things that should be considered before buying an aquarium tank. With the wide variety of options available in the market, it is extremely easy to get stuck and confused about which tank is best suited to become the home of your bettas and I hope that the reviewed list and the buying guide provided by me helped you in choosing the best tank for betta fish.
