Not many fish are as colorful and beautiful as betta fish. Also, not many fish are as picky as they are.

However, its beauty is worth it.

One of the special features of betta fish is the ease with which they can become irritated when placed in the same tank with other fish. They don’t like “roommates” very much and should stay alone.

That is why it is important to find a different type of aquarium for your betta fish, as opposed to the usual tanks used for other fish. To help you choose a tank more easily, here I’ve shortlisted the Best Betta Fish Tanks on the market right now.

You need an aquarium that can meet your needs. So what kind of aquarium is that?

Fortunately, I’ve done quite a bit of research and come up with some suggestions that will keep your Betta happy and healthy.

Bettas are bright, colorful fish that are easy to care for and perfect for beginners.

 

What Is The Best Tank For A Betta Fish

I have searched and reviewed a lot of aquariums for your beta fish. There are hundreds of aquariums available to purchase online. How did we decide what was best? It boiled down to the following criteria.

Size of the aquarium

Despite my research and experience in fish farming (over 25 years and still), the best aquarium size for a Betta is a 5 gallon tank. Anything smaller is too little space and is detrimental to your Betta’s long-term health. Anything larger is too much room for a single betta. Our focus in this review is the ideal aquariums for a single Betta. An aquarium kit is also preferred.

Filtration

I want a complete aquarium set. Ideally one that comes with a built-in filter unit. This makes maintenance easier.

To turn on

Ideally, I can find a lit aquarium suitable for beginner aquarium plants. Having plants in our aquarium will not only make it more comfortable for our betta, but also healthier as the plants filter our nutrients in our water. Today, LED lighting is the way to go. If the lamp is part of a lid, that is an advantage for me.

Aesthetic

I want our Betta tank to look good. I don’t want the gear showing up all over the tank. I want this aquarium to look good on a desk, cabinet or counter. I prefer a lid to avoid evaporation problems.

price

I don’t want this Betta tank to break your bank. It has to be well priced, but at the same time it has to be cheaply priced. If it’s cheap and offers me crap I won’t include it on this list!

What are the best tanks for beta fish?

This question is really hard to answer. There are many answers to this question depending on you and your betta fishing credentials. How old is your betta fish? What does he or she like?

We know one thing is for sure – betta fish should be kept alone and not with other fish as they would fight and most likely kill each other. But besides that, every betta fish is different and they all like different things.

If you already have experience with your fishing it is easy to see. If you haven’t, you may have to do some testing and fail before you can choose the most comfortable tank for your fish.

Some betta fish are very energetic; they would like to have a little more space in their tank for swimming and there may be more decorations to play with and hide too. Others like to live their lives calmly; these would not require that much space.

In addition to the fish’s needs, you must also consider its tastes and desires. Would you like a small tank for our desk? If so, how small? How big? Do you mind installing cables and electronics manually, or do you want them all pre-wired to save time and effort? Do you care if the lights are one color or do you prefer the colorful multi-colored LED lighting system?

The answer to each of these questions is an important factor in the overall decision you make about which tank to choose.

 

What temperature is best for the Betta fish tank?

Most betta fish tanks, even the one that claims to have a complete starter kit, do not include a heater. This will not be a problem if you live in a warm area throughout the year. However, it is a big concern if you live in places that have temperature changes during the winter.

Betta fish are originally tropical fish. They prefer warm water. The temperature in your tanks should never drop below 74 ° F (approximately 23.5 ° C). The ideal temperature is within the range of 78 ° F and 80 ° F (approximately 25.5 and 26.5 ° C).

Due to the demand for betta fish at high temperatures and if you live in places that have a cold winter, getting a heater for your tank is absolutely essential to keep your fish warm, healthy and happy all year long.

How to set up a Betta fish tank?

The way to set up a betta fish tank varies depending on the type of fish tank you have. Most of the time, the tank and its kit will come with a complete and clear set of instructions for everyone to follow easily.

In general, setting up a tank for betta fish is not difficult because they are often small in size.

You need to set up and assemble the tank itself. After that, you put decorations and gravel all over the tank. Depending on how you want to do that, it can take anywhere from 10 minutes to hours to decorate your tank.

Then you need to carefully connect the electronic accessories, including filters and lights. As stated above, the tank does not come with a heater. However, you know that you need to get them sometimes, depending on the weather. Remember to set the most suitable temperature for the tank so that the fish can be happy.
