Best Betta Fish Tanks Buying Guide & FAQ

What to Look for When Buying a Betta Fish Tank

First-time fish keepers can be overwhelmed when buying a betta fish tank. Many believe a simple bowl is enough to raise a betta fish. But it takes much more. Before going to the store to get your betta tank, you must be well-informed.

The most important thing is to choose your male and female ratio properly. If you plan on having multiple males, that might cause some fighting. Bettas fight for territorial purposes mostly, so you would need to make sure that doesn’t happen. You need to take great care of your betta and make sure it has a proper environment.

Bettas need plenty of space to thrive. They need to have plenty of space for swimming, but they also need to have some plants and decorations that will mimic their natural habitat and offer hiding places.

Apart from getting a large enough place for your betta, you also need to get some additional equipment that will make sure your betta lives in a healthy environment.

In the wild, bettas live in an environment that is a part of a large bio-diverse ecosystem. They are used to clean water that is oxygenated by many plants. Contrary to what people think, bettas are not used to dirty waters, despite living in paddies and shallow streams. They need an environment that is rich in oxygen. While living in a tank, a filter will provide this environment. A filter is a key to maintaining your small aquarium, which will keep your fish stress-free.

Bettas also need a heater that will be able to keep the water temperature at a steady level in a tank. Many believe that bettas can be kept without a heater, but the water temperature needs to be kept at a certain level, which only a heater can do. The only exception to having an aquarium heater is in case you live in a place with a warm climate, which will keep the temperature of the fish tank constantly warm.

You will also need to have a thermometer in place to monitor the water temperature. The thermometer should be kept at the opposite end to the heater, making sure that the water has the correct temperature entirely.

Most tanks should also have some lighting. If a kit you buy doesn’t have any lights, you should consider getting LED lights that will illuminate your betta tank. LED lights are energy efficient. And they will also help showcase the spectacular colors of your betta.

Bettas should also have a regular pattern of day and night. To provide them with that, you should get a tank that has day and moonlighting. With a proper distinction between day and night, your bettas will stay healthy, and you will be able to view the day and night.

Different Types of Betta Fish Tanks

Based on the use of the tank, you can find two main types of betta fish tanks:

  • Betta condos
  • Spawning tanks

Betta Condos are tanks that can house multiple males in a single aquarium. This condo is just a small tank that has walls between different parts. These dividers are placed in the tank to hang from the top and keep the fish separated into two or more different parts. They are also vented so that water can circulate through them.

However, there is some controversy about using betta condos. These single condos should be placed in different locations so that the bettas don’t have a clear view of each other if the bettas can see each other from different condos.

Bettas have great vision, so any visual proximity to other males and females could cause them to flare in a fight stance and lead to challenges that can cause them to be stressed. The stress caused by this can have a negative effect on the health of bettas, which can shorten their lives. Bettas that live in the wild do not experience prolonged exposure to rivals, unlike those in tanks.

Once they are placed in these condos, it will be best to separate fish with 12 to 15 inches of distance, with plants to hide behind.

Another type of betta tank you can find is spawning tanks that are used for breeding. These tanks are usually set up a few days or even a week before the spawning begins. They are usually 10-gallon tanks, but there are also smaller ones that can take 5 gallons. The most important thing is for the water to be 4 inches deeper and have specific chemistry for the breeding. These tanks also have a heater that will maintain the temperature to be 82°.

What Size Tank Does a Betta Fish Need?

Bettas mustn’t be housed in a small tank of fewer than 5 gallons. Even though they live in shallow streams and paddies, they can’t survive in small tanks. In fact, paddies are actually huge in size, so bettas have a lot of space to move around. So the same should go for the tanks they will live in.

In order to provide enough space for your bettas, they need to have a minimum of 5 gallons of water. The best betta fish tank size to keep multiple bettas is 10 gallons, so that they have enough space to swim and even hide.

Tanks of 20 gallons can provide enough territorial space to keep multiple males in the same place. Male bettas tend to fight for their territory, which can be problematic in smaller tanks for betta fish. In a 20-gallon tank, male bettas can spar briefly and then retreat to another part of the tank.

Best Betta Fish Tanks FAQ

If you’re just starting your fishkeeping hobby, then you must have numerous questions going through your head. To help you out with them, here are some of the most frequently asked questions.

A: There are many different ways you can set up a fish tank for bettas. How you set up the kit depends on the product itself. In most cases, the tank and its kit will have clear and detailed instructions that will help you set everything up if you follow them correctly.

The main part you need to take care of is to set up the tank itself. After you are done with the tank set up, you can proceed to set the decorations and gravel. Afterward, you need to take care of all the electronic accessories, like the lights or filters the kit might have. You also need to leave space for a heater, if you plan on adding it later.

A: Even though fish are cold-blooded animals, they mustn’t be housed in a cool fish tank. The same applies for bettas – they shouldn’t be kept in cool betta tanks. Betta fish are originally tropical fish, so they prefer living in warm water.

Fish are actually less active in cooler water, so keeping the tank water at a proper temperature is one of the priorities for fishkeeping. The temperature of betta tanks should be between 70° and 80°. The ideal temperature should be set to about 78° to 80° F or 25.5 to 26.5 °C for general maintenance. For spawning, the temperature needs to be a bit warmer.

How can you keep the water temperature at an optimal level? Many manufacturers have small heaters in their offers that are designed for small tanks. However, most of the kits don’t have a heater, so it needs to be bought separately.

If you are planning to keep many bettas in small containers, then you also need to heat the room they are in. It’s best you get a heater that will control the temperature properly. Another option is to have a row of containers that are heated once they are placed on heating mats that were designed for use with seedling plants.

Final Thoughts – Which Tank Is Best?

So what is the best betta fish tank? There is no right answer to this question. The best betta tank for you depends on the number of fish, the male and female ratio, and what you want for their home. You should carefully review all the necessary information, and decide what you need for and look for the right one.
