Tip 1: Don’t keep Your Betta In Small Bowl

You may often notice bettas are kept in small bowl or vases. But this is not a good way at all to take care of your betta fish. Betta fish have the capability of breathing air and surviving in an oxygen-depleted environment.

Bettas are able to do this thanks to their labyrinths. However, Betta fish don’t actually prefer small habitat. They tend to use the environment to avoid predators and competitors. Being aggressive, living in a small habitat will limit their chances of survival.

Bettas are sensitive to the effects of ammonia exposure just like every other fish species. They are also prone to feel hot and swim bladder diseases. Having a poorly maintained or small fish tank will increase the susceptibility to these diseases and infections.

So, if you own a Betta fish, you should also ensure that you have enough space to thrive and survive on their own.

Recommended Size For Betta Fish Tank

The minimum tank size for a Betta fish is 2.5 gallons but we will recommend for 5 gallons or more. A big tank will make maintenance quite easier. You’ll be able to maintain temperature and nitrogen cycles easily. One of the other things that make larger tanks the right option is that they require less cleaning. One of the false beliefs regarding betta is that it can live in a small bowl or vase. Surviving in a small tank is quite different from living in a big tank. Just because betta fish can survive in a small bowl doesn’t mean they will live healthily.

Back in the wild, bettas live in shallow streams, puddles, and rice paddies; All of which are oxygen deficient. If they have a lack of oxygen, they will make up for it. Your betta fish should have enough room to swim around as well as spots to hide.

Avoid filling your tank to the maximum volume. Betta fish need access to the tank surface to gulp in the air using the labyrinth. The labyrinth organ is responsible for extracting oxygen from the air as a perfect substitute for their gills. You should have a led on your tank as bettas are great jumpers. If your betta fish jump out of the water, it’s hard to save them. You can take a look at this article on why bettas jump out of water.

Tip 2: Ensure Perfect Lighting For Your Betta Fish

Both natural and artificial light will be just fine. Betta fish need both forms of light while they are awake during the daytime and darkness at night to enable them to sleep properly. These tend to establish a regular day and night pattern, and it also regulates their internal biological clock. They also need plants and other decorations as these plants can provide shade.

Exposure To Direct Sunlight

Sunlight can quickly raise the water temperature to turn on the comfort level and thereby triggering unwanted algae growth. A perfect substitute would be artificial lighting. You should also place your Betta fish tank away from Windows. With artificial light, you’re able to control lighting during the daytime and at night.

Tip 3: Keep Your Betta Fish Safe From Diseases

Even though bettas are really strong (health-wise), this doesn’t make them invincible. They also get sick. But to minimize the risk, you have to look after them and spend quality time with them.

When it comes to issues that are common to betta fish, the infection that develops after a cut is the popular one among them. These tiny but deadly scars and cuts will lead to deeper infections that are deadlier. The usual culprit is the sharp substrate. Make sure these substrates are smooth and safe for your betta. You should also take note of the decors you’ve installed in the tank as they can be harmful too.

Asides sharp substrate, most other diseases can develop when the water is polluted. For instance, fin rot occurs when the water is not kept clean. It is a bacterial infection that causes inflammation and irritation. This disease can also be triggered when an infected tankmate is introduced into the tank. This could happen through aquarium equipment borrowed, or poorly cleaned equipment or substate. However, you need to understand that fin rot can be a symptom of other diseases.

Another condition that is worth talking about when it has to do with knowing how to care for a betta fish is constipation. Often seen as a disease, it is caused by overfeeding. When you overfeed your betta, it leads to a damaged digestive system. This is why it is necessary to starve your betta once a week.

Tip 4: Feed Your Betta Fish Regularly

So, giving your Betta fish a pinch of food that is a small as his eyeballs would be great. You need to understand that they won’t stop eating. This is why you should time yourself while feeding. Whatever he is able to eat within two minutes should be enough.

2. Feed them regularly.

Forget what you’ve heard about Bettas going for days without food. The maximum number of days betta can live healthily without food is three days. Make sure your betta is fed daily. But it’s ok to skip a day to avoid overfeeding and in the long run, constipation. We recently wrote an article on how to feed your betta while on vacation. If you go on vacation for days, you will need to have someone come in to help with the feeding. A betta will be fine if it goes hungry for a day. You shouldn’t feed him extra before you go or after you get back. Just stick to the same quantity of feed even if you skip their meal a day.

3. Different Diet Will Do The Trick.

Bettas aren’t supposed to eat the same meal all the time. At least, make sure to add something different once in a while. You can also choose two different foods and alternate between them each day. Need some ideas? Here are some ideas that will be of great use to you:

  • Brine shrimps.
  • Pieces of frozen beef heart.
  • Frozen or dried bloodworms.
  • Fruit fly larvae or fruit flies without wings.

4. Don’t Feed Your Betta Fish Only Pellets Or Dried Flakes

One important part of taking care of a betta fish is knowing when to change things. Giving your betta fish pellets or dried flakes all the time should be avoided. While it’s ok to feed them with these food options, consuming them daily will affect your betta in a negative way. If you are opt-in for dried foods, you should soak them first before feeding your betta.

Tip 5: Choose Your Betta Fish Tank Mates Carefully

Most bettas are aggressive and won’t tolerate any tank mate. They prefer living in solitude and will be aggressive towards the other inhabitants. However, they can play it cool with some tank mates that don’t have bright-colored skin, long fins or are not aggressive.

You can enhance their ability to stay with other tank mates by adding them to a community of fish in a larger tank. Make sure the large tank has enough spaces and spots to hide. 8 – 10 gallons tank is highly recommended. When you have enough space in the tank, it will reduce the territorial instinct of the betta fish and may ultimately lead to a decreased aggression in the betta fish. You can learn more about this by asking local stores around you.

Avoid putting two males in the same tank because they will always fight and nip at each other. This may continue until one or both is dead. Males should never be housed with another male. However, they exhibit this same aggression towards female bettas too. Female bettas, on the other hand, can live together in groups for a long time. You just have to make sure the tank is 10 gallons or more.
