Top Betta Fish Tanks Comparison Table

Must Know before you go

  • Betta fish are also known as Siamese fighting fish.
  • If you don’t want to see a sad face of betta in the tank, pick a big aquarium. They will love it.
  • They are tropical fish, and very territorial, so they can’t be kept with other male bettas. Instead, keep them with the types of fish that they will tolerate, such as Plecos or Minnows.
  • The water in your fish tank needs to be heated to a constant temperature at all times.

What type of Fish aquarium is required for betta fish?

Betta Fish need a tank of at least 2 gallons; You can keep them on 1 gallon, but anything smaller than that is not fair to the fish. The water needs to be heated to 78 degrees F, and ideally filtered. The bacteria that build up in the filter are essential for breaking down the ammonia in the water that is caused by fish waste and uneaten food.

You can have two female bettas, but then you must have a tank of sufficient size and a divider. You really wouldn’t want them to attack and injure each other. People have kept groups of female bettas. However to keep those you need large tanks like 20 gallons or bigger, with plenty of space and cover, as bettas love to have places to hide away

 What to Consider before buying a best betta fish tank?

The Tank: Bettas are not very happy in smaller tanks. When you keep him in a larger tank, he feels safer and swims actively. The smaller tanks also need very frequent cleaning. You’d need 100% change every second day to prevent the build-up of ammonia, which is extremely toxic. Acrylic, as opposed to glass tanks, are another consideration. Acrylic scratches more easily.

Temperature: Bettas are tropical fish, and they need the water to be constantly heated to about 78 degrees F with no sudden temperature fluctuations. If you have purchased a kit specifically geared to tropical fish, it will come with a heater. If you are doing a DIY setup, you will need to purchase a reliable heater that fits easily and unobtrusively into your tank.

Filtration: Ideally your tank should be filtered. When you clean your filter medium, you must never get rid of all of it at once, as that will set your tank back to “new”. If you don’t have a filter, you will have to change 100% of the water every second or third day.

Decoration: Bettas need a variety of objects to occupy themselves. They also like nooks and crannies to hide away in. You can have fun decorating your tank to make your fish feel at home. Some people don’t want to go through the hassle of trying to cultivate living plants. If you opt for the option of artificial plants, buy silk rather that plastic plants. The plastic plants have very sharp edges that could damage your friend’s fins.

Maintenance: Your fishy friend’s home must be maintained at the correct ph level and temperature at all times. Never put fresh tap water into the tank, it needs to have water conditioner added first to get rid of chlorine, chloramines, and heavy metals. When it comes to food, your betta doesn’t like to be fed pellets only. They will obviously love live, but frozen food, such as brine shrimp or bloodworms is more than adequate.

We have reviewed a few of the many hundreds of different aquariums available on the market. We hope that this will make your choice a little easier. Choose best betta fish tank carefully.

How to Set Up a Betta Fish Tank?

The very first thing you should consider is the tank. Smaller tanks get dirty very quickly and require complete water changes every 2 to 3 days. With a bigger tank and with a decent filtration system it becomes possible only to change 10 to 15 % of the water every week. Which let’s face it, is much less stressful for your betta. There are many great starter kits on the market with some great features, so the choice is an aesthetic as well as a practical one. You can, of course, build up your own system from scratch. However, although components may be better quality, they will be more expensive.

The next thing to consider is the accessories that will enhance the comfort of your betta, namely, the filter and the heater. The first we will consider is the heater. Bettas are tropical fish and need a constant water temperature of between 77 and 80 degrees F. The starter kit aquariums typically come with a heater, and again, the size of the tank is critical. Too small a tank and the temperature fluctuations will be too great. If you are building your own kit, don’t hesitate to spend a bit on a decent, reliable heater to keep the water temperature constant. Always test heaters before entrusting your fish’s health to them.

Then, the filter and pump. Again, most starter kits come with some kind of filtration system. As mentioned before, it is sometimes difficult to attach filters and pumps to smaller tanks. They’re also harder to decorate. Bettas don’t like strong currents, so, if your pump is too efficient, simply baffle the outlet with a sponge pre-filter. You can even get special sponges for exactly this purpose. Filtration systems are there to control the build-up of ammonia. Ammonia build-up, which is toxic to the fish, is caused by the presence of untreated fish waste and uneaten food. A decent filtration system will normally be composed of a three components, mechanical, chemical and biological. To ensure that your system is working properly, you should test the water for ammonia, nitrite, and nitrate. All these substances should be at 0, or as close to it as you can get.

Next, it’s time for the decorations. Bettas are lively, inquisitive fish and love lots of little nooks and crannies in which to hide and swim in and out of. You should put some kind of gravelly substrate on the bottom of your tank. This will anchor your plants, real or fake, and your decorations. It also gives your aquarium a more natural look. The good idea is to have a themed tank, such as Sponge Bob, or a fairy garden with an obligatory castle. If you choose plastic plants, make sure that they have no sharp edges as these can damage the bettas’ fins. Silk or real plants are preferable, but cultivating real plants could be somewhat tricky and time-consuming. If you don’t trust yourself to grow water plants, silk ones are excellent. Half fill your tank before placing plants as this will help you to anchor the plants.

Once all this is done, and the tank is full of water, you need to institute a fishless cycle otherwise your betta might fall prey to “new tank syndrome”. This fishless cycle allows the tank to start building up a supply of essential bacteria in the tank and filtration system. This will break down the ammonia mentioned earlier. Once your ammonia and nitrate readings are 0, it is time to add your fish and enjoy the incredible experience that keeping bettas gives. One last point: don’t ever put fresh tap water in your tank. The water needs to be treated with water conditioner to eliminate chlorine, chloramines, and heavy metals before adding it to the tank.

How to Create Ideal Betta Tank

  • Most people assume that by using a small Betta bowl it won't require as much time to clean. However, this isn't true at all, the smaller the container, the more often you will need to clean it. And, you may not be able to provide your Betta with the right water temperature if you can't use a heater.
  • Experts recommend that you have at least a one gallon Betta tank for each fish. However, the ideal aquarium is from two to five gallons and more if you want a larger tank. By having a larger tank, you'll be able to take advantage of a heater and a filtration system.
  • Bettas don't need aeration, they can breathe air from the top of the waters surface. But, clean water is one of the most important factors in keeping your Betta healthy. Waste that accumulates in the water will quickly decay and it can cause fin rot, or make your fish very sick.You'll also need a good heater that is the correct size for the tank that you're using and a thermometer. Bettas need warm water temperatures that range from 70 to 80 degrees. Temperatures that rise and drop constantly can be fatal to the Betta.
  • If you're purchasing a new Betta tank, try to find one that has a cover. Not only will a tank cover help keep dust and other particles out of the water, it will keep your Betta in the water. Bettas love to jump and can easily jump out of the tank.Besides helping to keep the tank cleaner and keeping the Betta from jumping out of the tank, most tank covers are equipped for lights. And, while you should never sit the tank in direct sunlight, your Betta needs light to stay healthy. It should have at least eight hours of light every day.
  • You can use almost any type of substrate in a Betta tank. However, rough gravels or other rough materials can destroy the delicate fins. The ideal substrate would be small, smooth gravels or sand. But, if you want to add a decorative touch, you can even use marbles.Bettas love hiding places and they like to have decorations to swim through. Just make sure that whatever you decide to use in the tank is smooth and doesn't pose any danger to the fish. If you want to use plants, choose either live plants or silk.The location of the Betta tank is just as important as the tank itself.
  • You'll want to place the tank in a location that you'll be able to enjoy the Betta. But, make sure that it's not sitting in direct sunlight, or where it will be exposed to any hot or cold drafts.After you've decided on the perfect location for the Betta tank and have the tank decorated, you're ready to add the water.
  • It's perfectly safe to use water from you sink as long as you treat it properly. It's crucial that you use a chlorine neutralizer because chlorine will kill a Betta.It's also a really good idea to use a high quality water conditioner. A water conditioner will remove any harmful metals from the water such as copper and zinc. And, most conditioners will even remove excess ammonia. You can purchase spring water, but tap water that has been treated is much better
Frequently Asked Questions:

1.Can I put more than one betta in the same tank?

Answer: ​Generally, NO. However, if the tank is big enough, you can build up a collection of female bettas. Just ensure that there is sufficient space for them to move around in, and places where your bettas can hide.

2.Can I use Full Mirror?

Answer: Not generally advisable. Your betta will get very stressed thinking there’s another male with him in the tank. Avoid mirrors altogether.

3.Is it alright to feed my betta just fish flakes and pellets?

Answer: Fish flakes and pellets are adequate but not ideal. They can cause bloating and should be soaked before giving to the betta. Fresh food is best, but frozen will do, and ideally, a combination of all three.

4.Do Bettas hate currents?

Answer: Because of the configuration of their fins, bettas do struggle against strong currents. I have known bettas to swim against the current and then pull aside to rest, almost as if exercising. Baffle your outlet with the sponge if you think the current is too strong.

5.How much water conditioner must I add to the water?

You only use water conditioner when you do water changes. You must only treat new water, and you don’t use if you are not changing water.

6.How many pellets must I give my betta?

Answer: Two pellets twice a day is enough.
