Betta fish, also known as Siamese fighting fish, is a tough fish that is very easy to maintain and can live upwards of three years, provided that you care for it properly. Provide this betta fish with everything it needs to live a healthy life, and it will stay vibrant, colorfully sharp and happy for a very long time.

A Little Bit About The Betta

Bettas, (also known by their Latin name Betta Splendens), are originally from the muddy streams, ponds, and rice paddies of Thailand and Cambodia. The original bettas had dull coloring and short fins.

But bettas of today have long flowy fins and they come in all sorts of sharp colors, mainly because of genetic mutations and breeding. Their long fins are a primarily a unique feature of the male betta. Female bettas are, generally speaking, have shorter fins and are a bit smaller in size.

Another trait that sets male bettas apart is their aggressiveness. Male bettas are more aggressive than female bettas (like most males of most species, including human males), therefore you should not keep two of them in contact together where they will fight each other until one of them is dead.

How to House and Maintain a Betta

It is very essential that Bettas are kept in a large bowl or a good sized tank (preferably 2.5 gallons or more). They are a tropical fish therefore are most comfortable in temperatures between 24-27 Celsius. A tank heater is a useful accessory to have a healthy betta. Get a thermometer to maintain a consistent temperature as ambient temperatures are too cool for bettas.


You don’t really need to buy a filter but if you do use one, make sure the filter flow is on a low setting as Bettas don’t like a lot of agitation in the water. You also have to take precautions against your bettas getting their fins stuck in the filter intake.

Bettas also love a good hiding spot. So try to get some plants or little cave decorations. Old coffee mugs can also work. Make sure the fake plants are not a hard plastic in order to avoid fin damage. Large leafed silky plants are ideal.

Water changes: An unfiltered tank needs 50% water change once every week. A larger (5+ gallons) tank, that has a filter may only need 20-30% change once a week. Ammonia is produced from fish waste which is harmful even in small quantity so it’s very important to use a water conditioner after you add water to your Betta’s tank.

The conditioner also removes toxins from tap water that can be a cause of death for your fish. Add some gravel at the bottom to keep waste from floating around the bowl. It prevents the bacteria from growing and also looks very nice! Also make sure that the water you are adding to the tank is the around the same temperature as in the tank to avoid shocking your betta.

Best to keep the water in a container for some time near the fish tank and then pour it in slowly to avoid stressing the fish. If you do remove your betta from the tank when changing water, let it float in a cup for about 10 minutes before releasing it into the tank.

Feeding: Bettas are carnivorous, so use pellets that are high in meat based ingredients like fish or shrimp. Frozen bloodworms, brine shrimp, or glass worms are some of the popular Betta foods.

Don’t overfeed your betta otherwise you will cause it to be obese, which will result in a messy tank. Just feed them no more than 2-3 pellets twice a day. One pellet 3 times a day is ideal. Also remove any uneaten food daily because the pellets swell in water and can clog up the filter.

How to Prevent Your Betta from Getting Sick

As mentioned earlier in this post, poor water quality can cause the Betta to be sick and the bacteria in the tank can cause fin rot in the fishes. Fluctuating water temperatures are also a major cause of sickness. If you keep up with regular water changes and ensure constant water temps, then the chances of your fish getting sick is low.

But if your Betta fish gets sick there are a few things you can do…

If your fish is showing signs of fungus infection (white, cotton-like patches on the body) then add a bit of Jungle fungus eliminator (35 grams per half gallon). Keep changing the water every few days and adding the above medicine. You should also add aquarium salt to a new water change to keep the water quality healthy. If you notice fin rot Maracyn-2 or MelaFix in addition to aquarium salt.

Remember; anytime your fish shows abnormal behaviour or unusual signs, do a 100% water change, clean the tank (vacuuming gravel) and give them quality, nutritious food.
