What Makes Betta Fish Different Than Other Fish?

Betta fish are nicknamed “Siamese fighting fish“, and not for nothing. They are quite active and also one of the most easily aggressive fish species. They do not like the presence of other tank mates so easily and hence should be kept separate. Another thing is that Betta males compete for space and dominance. Hence, two Betta males in the same tank can also spell trouble. They also like to zoom and zip around the tank as they are quite active.

Betta fish are Southeast Asian tropical fish. Cold temperatures below 65°F can kill it. Hence, you’d have to maintain a temperature between 75°F to 82°F and not let them be subjected to long periods of cold.

Betta fish also like to nestle among the leaves of the plants but they do not eat it. Hence adding plants to the tank can be a good addition.

One of the greatest myths surrounding them is that they can live in small bowls or small aquariums. But that is not true. You will require at least a 5-gallon tank to start with if you had to keep it as a pet.

So, these need special tending. You need to change the water regularly, feed the fish a varied diet. They do not eat plant elements and are meat-eating fish. Be very careful while putting them in the same tank with other fish as they are quite aggressive and avoid letting the water get cool for a prolonged time.

Things To Consider Before Getting an Aquarium Kit For Betta Fish

The size and shape of the tank

Betta fish might appear small in size but they need a large enough area to swim around freely. Contrary to the popular belief, Betta fish do not do good in cup like containers or glass balls at all. A fish confined to such small environment live very miserable life.

So the minimum size of the tank you need is 5 gallons. The larger the tank the more space for plants, heater, filter and lights you have.

Another important factor is the shape of the tank. The circular shape of a bowl provides with small surface area for oxygen exchange and thus lowers the quality of the water. Rectangular or square shaped tanks allow for better oxygenation and more swimming space.

Filtration and lighting factors

Like any other fish, the Betta fish also need clean water to thrive. Filters and plants added do keep your tank toxin free. There are many aquarium kits listed in our list above that come with pre fitted filter. These filters ensure that the aquarium is effectively cleaned. However, you have to make sure that the water flow of the filter is not too high as these fish like low flowing water to swim.

The lighting unit should also be checked. Light time and dark time allows the fish to set up a sleep wake up pattern and also sets up feeding habits. The lights should provide with full spectrum natural light and should not overly heat the tank.

Other factors

You might want to check the material of the tank too. Whether it is made up of glass or acrylic, both have their own advantages. Glass is more durable, cheaper and heavier. Whereas, acrylic is lighter, more shatter proof but expensive.

Make sure the lid is secure as Betta fish are notorious for jumping out of the tank.


How do I setup a Betta tank?

  1. Pick the perfect spot for the tank. Make sure it is away from direct sunlight and also make sure you have space around for filter and heater.
  2. Put the filtration unit in. Check if it has any cut-outs for filtration fitting.
  3. Place the substrate. Rinse the gravel but don’t use soap.
  4. Put in the plants if you want to have some vegetation in the tank. Bettas love nestling under the plants.
  5. Pour in the water and run the filtration unit.
  6. Connect in the water heater.
  7. Pour in the water conditioner in case you are using tap water.
  8. Release your Bettas in the tank.

What is the ideal temperature for Betta fish to live in?

Bettas are tropical fish. They cannot tolerate cold temperatures for long periods of time. They need water temperatures to be at a range if 75°F to 82°F.

How frequently should I clean the tank?

If you have a tank smaller than 5 gallons (you shouldn’t), you need to clean the tank 3 to 4 times a week. If you have a larger tank, make water changes of 25% once each week and have proper filtration unit and water conditioners to help you with cleaning the water.


There can be many mistakes you can commit during the process of keeping you Bettas especially if you are a beginner. While we shouldn’t be afraid of making mistakes, we should do our utmost best to cut down on the mistakes.
