You will get different answers if you ask other people which one is the best Betta fish tank. In our opinion, the best Betta fish tank is the one that is comfortable and cozy for them, where they can live happily. A Betta fish can live two times longer than its expected life span of 2 to 3 years in an ideal aquarium.

In this article, we’ll try to give you an idea of how you will choose your Betta fish tank. We provide a list of Betta tanks to make your search process more manageable so that you can pick one quickly if you are in a hurry. You will get a detailed review of the products in our review sections. Hopefully, that will be useful for you as a buying guide. 

Essential Things to Know About Betta Fish

Just because they are fighters doesn’t mean hard to keep. Despite their aggression, Bettas are one of the low-maintenance aquatic pets! You need to know some basic things about Betta fish to handle them well.

Origin and Diet

Betta or Siamese fighting fish are native to the Mekong basin of East Asia. They are small fish, and a full-grown Betta can be 3 inches in size. Betta’s expected life span is 2-3 years in the wild, extending to 4 years in captivity.

They are carnivorous, and they feed on zooplankton, small crustaceans, and the larvae of mosquitoes in the wild. In aquariums, they take prepared pellet foods or frozen foods. 

Tank Companion

Male Bettas are furious! In aquariums, they cannot cohabit with their female counterparts, so you have to keep them single. But female Bettas are comparatively sober enough (still aggressive), and you can try to keep two or more of them together.

Tanks with multiple female Bettas are known as Betta sorority tanks. In that case, don’t forget to provide them a sizeable spacious aquarium. Making a Betta sorority aquarium is not that easy. It needs some research, so we don’t suggest this method for first-timers.  

You can keep some peaceful tankmates in a spacious aquarium of more than 10-gallon. Blue Gourami, Neon Tetras, and bottom feeder catfish like Bristlenose plecos, Glass catfish, or Cory catfish can be excellent Betta companions in an aquarium. 

Basics of a Betta Aquarium

Bettas are highly active fish, they love to swim around, and an ample space comforts them. A five-gallon is the minimum size of a tank to relax a single Betta fish. Conversely, small tanks from 0.7 gallons are relatively standard for Betta keeping! But if you ask us, we will recommend you ‘larger is better’! Because you will love to see your pretty friends playful enough! Aren’t you?

They love to play hide and seek (but sadly when they are unhappy), showing their mood. A natural biotope aquarium can please Betta fish a lot. To add natural flavors in a Betta tank, you can add live aquatic plants. Floating live plants can be the right place for them to hide behind. Live plants beautify your aquarium gorgeously as well.

Bettas are from paddy fields of the east and south-east Asian warm zone, and so, they do well in warm temperatures like 76 to 78 degrees Fahrenheit. An effective aquarium heater can keep them warm and happy.

They prefer low flow or even no flow in their home because they are a type of labyrinth fish who can breathe air. Although Bettas are okay with low oxygen water, a little water flow is good for maintaining your aquarium water quality. A filter & pump package with an adjustable flow rate can be the perfect choice for a Betta Fish Tank.

The Criterion that Makes a Tank – The Best Betta Fish Tank

You are pondering to select the best Betta fish tank, aren’t you? No worries, we are here to help you further, now we’ll talk about the qualities that an ideal Betta fish tank should possess.

Tank size:

We said earlier, size does matter, and the larger is better! As a type of labyrinth fish, Betta can live in low oxygen water, so some people keep them in small bowls. Though they can survive, it does not mean a small tank is ideal for them.

The real beauty of Bettas resides in their social behavior that you cannot get unless you keep them in a large aquarium. So the best Betta fish tank is the perfect spacious one. You should choose a minimum of 5-gallon, but 10-gallon or more is the best as Betta fish tank.  

A suitable filter:

The filtration system is a crucial criterion for selecting a Betta fish tank to maintain the water quality and keep the water circulation rate comfortable. 

The primary target for your aquarium filter is to achieve clean and healthy water, so the filtration must be proper. At the same time, the water circulation rate should be optimum. If the filter pump output rate is too strong, your Betta struggles to cope up. So the best choice for Betta fish tank is a three-stage filter with an adjustable pump. 

Temperature control:

All Bettas are tropical fish, came from paddy fields of South-East Asia, so very naturally, they are comfortable at a warm temperature. You should maintain your aquarium water temperature from 76° to 80° Fahrenheit and never go below 74°. 

Lower temperatures weaken their immunity, so they suffer from fungal and other diseases. It would help if you had an aquarium heater to keep water warm. Only in some aquarium kits (such as Aqueon 10 Gallon LED Aquarium Kit), a heater is available with the package. Otherwise, you have to buy one additionally.  

Space at the top:

A labyrinth type fish can directly breathe oxygen from the air, so Bettas love to come up to the water surface and take a quick breath like Dolphins. You should select a tank where you can provide a 4-inch gap from the water surface to the container’s edge. Some fish tanks with portrait shape like Marineland Portrait Glass Aquarium Kit gives an advantage for this point.

Live plants and no plastic plants:

Live plants inside your aquarium can create an environment that Bettas like most, as it gives them hiding places. But avoid plastic plants as those might have sharp edges. Betta has beautiful but sensitive fins, and sharp edges can injure your Betta.

Frequently Asked Questions

Here are the answers to the frequently asked questions that we often receive to give you a better understanding of how an ideal Betta fish tank should work.

What size tank is suitable for a betta fish?

In our article, we discussed it in detail. Bettas are super flexible fish; they can survive even in a small jar of half a gallon. But it does not mean a half-gallon container is the ideal one for a Betta. The larger space they get, become more cheerful and lively. 

Typically 5-gallon is a standard size for a single Betta, but a 10-gallon is better. In a 10-gallon tank, you can keep a single Betta fish with some compatible tankmates of other species. A 5 to 10-gallon aquarium with suitable facilities is considered the best Betta fish tank.

How often should I clean a Betta tank?

Usually, once a month, it depends on the tank size, filtration, and cleaning features. If your tank is smaller than 2-gallon and without a filter, you should clean it twice a month. 

Your cleaning’s main intention is to keep the inside environment healthy, so the frequency depends on how quickly your tank is getting dirty. If you have a large tank with low fish density and an effective filtration system, your tank condition will remain neat and tidy longer.

How often should I change the water for a Betta fish?

It depends on several factors, mainly on your tank size and the aquarium filtration system. If you have a tank with a perfectly functional filtration system, you should change 20% of the tank water every week. Whereas in a smaller tank without filtration, you should change at least half of the water twice a week.

Why does my Betta tank become dirty so fast?

Probably you are feeding your Betta too much! Feed them only as much as they can finish in two minutes. If there is any leftover, remove it and lessen your food supply. Another common reason for this can be too much fish inside an aquarium. Remove some tankmates of your Betta.

If you have a Betta sorority tank, reduce the number of its members. The main reason why a fish tank gets dirty quickly is too much fish waste and food leftover. If you can minimize it, you can resolve your problem.

 Can I use tap water for Betta fish? 

Tap water is perfectly okay for aquarium use unless Chlorine is present in it. Chlorine and its compound are harmful to fish. If excessive Chlorine or Chlorine compounds are not present in tap water, there is nothing to worry about.

What is the best filter for a betta tank?

The filter output should be moderate to be suitable for Bettas, as the struggle to cope with the flow if it is too high. So take an adjustable flow filter for your Betta fish tank. For detailed information, check our article regarding aquarium filters

How do I know if my Betta is happy or not?
