Buyers’ Guide


How do I Choose the Right Betta Fish Tank? 

Bettas are very popular fish to keep in aquariums due to their bright colors and long, brilliant tail fins. However, you must keep in mind that Bettas require proper care and maintenance in order for them to thrive and be healthy. 

Firstly, you have to figure out how big of a fish tank you need to get. There is no upper ceiling, it’s usually preferred that you get as big of a fish tank as you possibly can. As for the minimum size requirement, there is something called the “one inch per gallon” rule. This says that for every inch of fish that you have, you must have at least one gallon of water capacity in your aquarium. So, if you have just one Betta, we recommend getting an aquarium that is at least 1-gallon in size. 

Water quality is the second most important factor when it comes to getting a fish tank for your Betta. It’s a common misconception that smaller tanks don’t need filters. This is a myth and you should not fall into this trap. No matter how small your aquarium is or how little fish you have, they are still going to be producing waste that needs to be cleaned out. In fact, smaller aquariums need to be cleaned more often than larger aquariums since they contain more waste products in a lower body of water as compared to bigger fish tanks. Hence, be sure you’re getting an aquarium that has a filter which can clean the water or at least ensure that the aquarium is built to support a separate filter that you would buy with it.

Another thing to think about is lighting. When people talk about lighting, they talk about it in terms of aesthetics. We agree that aesthetics are important. You bought Bettas because of their brilliant colors. It kind of defeats the purpose if you don’t have appropriate lighting that is able to show off their bright shimmering skin. However, along with the aesthetic aspect, lights are also necessary for the growth of your Bettas. LED lighting mimics natural sunlight and provides your Betta with a natural environment that makes it calm and stimulates growth. It is an important piece of equipment to have so make sure your aquarium comes with built-in lighting or at least, is built in a way so that it can accommodate separate lighting.

How do I Set Up a Betta Fish Tank? 

Most Betta Fish Tanks come with their own unique set of instructions depending on their design which you can follow in order to easily set up your aquarium. 

However, as a general guideline, we recommend that you follow this order to have the best possible experience with your Bettas: 

  • Decide where in your home you want to place your aquarium and then set it up and its frame in that location. 
  • Mount all the equipment such as a filter, air pump, heater, etc. 
  • Add gravel, decorations and aquarium plants. It’s preferable that you place the decorations and plants in such a way that it covers your equipment such as the filter and heater. 
  • Double-check to see all the equipment is properly plugged in and turn it on. 
  • “Cycle” your aquarium. This refers to letting the equipment run for some time in order to grow beneficial bacteria inside the aquarium. 
  • Add your fish into their new home.

What Temperature is Suitable for a Betta Fish Tank? 

Most aquarium kits, even the ones that claim to have “everything you need”, don’t come with a built-in heater. 

This is not always a requirement if you live in tropical regions where the temperature is warm all year round but if you live in colder areas, it is absolutely necessary that you invest in a heater for your Bettas. 

Bettas are tropical fish that require the water to be warm. A Betta cannot survive in water that has a temperature of anything lower than 23 degrees Celsius (74 degrees Fahrenheit). The ideal water temperature for Bettas is about 25 degrees Celsius (78 degrees Fahrenheit).

How Big of a Fish Tank should I get for my Betta?

As we mentioned above, the bigger the better. However, at a minimum, you should have 1-gallon of water capacity for every 1 inch of fish you have. So, if you have a total of 3-inch of fish, you should get a fish tank that can hold at least 3-gallons of water.

Frequently Asked Questions (FAQs)


What other species of Fish can I put in with my Bettas? 

Bettas can live harmoniously with other species of fish in a community fish tank but it is extremely important that you don’t put male Bettas together in one tank. They are called Siamese Fighting fish for a reason. Male Bettas will be very aggressive towards each other and will inevitably fight and tear each other’s fins. 

Female Bettas can be kept together and other species of fish that are good companions for Bettas are Guppies, Kuhli Loaches, Neon and Ember Tetras, Ghost Shrimps and Cory Catfish. 

I just put my Betta into its new Fish Tank and it’s refusing to eat, what should I do? 

The first thing you should do is to not panic as this something that’s extremely common in Betta fish that are placed into a new environment. 

Being introduced to its new home can be a shock for a Betta and it’s perfectly reasonable that it’s not eating as it’s taking time to get used to its surroundings. Don’t worry about it starving as Bettas can survive many days without food. 

Just keep dropping food into the tank from time to time into the tank, your Betta will slowly come around after a couple of days. 

If it still refuses to eat after a few days have passed, you could try changing its diet. A good idea is to boil and blanch vegetables such as peas, Zucchini or Broccoli and try feeding that to your Betta.  

If everything fails, we recommend contacting your nearest veterinarian or local pet store.

How do I ensure my Betta stays healthy? 

There are several measures you can take in order to ensure your Betta’s health. 

The first and most obvious measure is to check your water conditions constantly and make appropriate changes whenever there’s a drastic increase in any factor. Fish waste causes ammonia levels in the water to rise and the oxygen levels to lower. This will cause increased stress in your fish and breathing problems if it isn’t addressed immediately. This problem can be solved by installing an appropriately-sized filter for your aquarium and by making semi-regular water changes. Changing 10-15% of your tank water every week is usually a good idea when maintaining a Betta fish tank. 

Another measure is to keep it with compatible tank mates. It’s usually preferred that Bettas be kept alone in a tank as they are very aggressive. You should keep a check on your fish in order to make sure they are living harmoniously. If you spot any scratches on your Betta or a torn fin, we recommend you put it in a separate smaller tank where it can live a peaceful life in solitude. 

How regularly should I clean my Betta Fish Tank? 

It is usually preferred that you do small clean-ups after every few days with more thorough cleaning once a week or month. 

What we mean when we say “small clean-ups” is removing any leftover food with a cleaning net, checking and cleaning the walls of your aquarium to prevent algae buildup and cleaning any clogging in your filter or other equipment. 

The “thorough cleaning” refers to water changes. It is essential that you do water changes in your aquarium in order to make sure your Bettas are living in clean, fresh water. You can do this by changing 10-15% of the aquarium water once a week. Be sure to treat this water with a dechlorinating agent before you add it to your aquarium. Chlorine is good for us but is poisonous for your fish. 

What does “Cycling” a Fish Tank mean? 

“Cycling” a fish tank refers to letting it breathe in its controlled environment in order for the growth of beneficial bacteria in the tank. 

There are two types of cycling: the first kind is done without any fish in the tank and the second kind is done with a small number of fish. We recommend that you perform both types of cycling before you start adding the rest of your fish into the tank. 

Final Verdict

With Bettas being so popular in the market, it only makes sense that all these brands are capitalising on the opportunity by bringing us so many different varieties of aquariums for them. 

In the end, we have to go with the MarineLand 5 Gallon Portrait Glass LED Aquarium Kit. All its built-in equipment is neatly tucked away in order to prevent any visual clutter and the large sliding canopy makes it easy for you to feed your fish and clean the aquarium.
