What is the oldest betta fish?

In this post, we will answer the question “What is the oldest betta fish?”. We will also list and discuss some actions you can take to prolong your betta fish’s life.   

What is the oldest betta fish?

The oldest betta fish is believed to reach around 10 years old. However, there is no scientific record of the real age of this betta fish. 

How long do normal betta fish live?

There is currently no established method of extending the life span of a betta fish. Betta fish, also known as hepatic lipidosis, are susceptible to fatty liver disease. There are several symptoms, including a pale look, rotting ends, cloudy vision, skin rashes, and a lack of movement. 

Providing clean, filtered water is an excellent method to avoid this situation. Maintaining a routine for the diet of your betta fish. No matter how nutritious your diet is, you should avoid overeating or undereating at any point during the day.

It takes an average of three years for a betta fish to reach maturity. However, with correct feeding, enough clean water, and sanitary circumstances, you may significantly increase the lifespan of a betta fish. Even yet, a betta fish has a longer life span — it may live for up to 5 years. 

It is quite unusual for a betta fish to live for more than 5 to 10 years. Betta fish can live up to 9 or 10 years in captivity under regulated environmental conditions and away from other species that are considered to be very long-lived.

How long do betta fish usually live in tanks?

The fact that you may anticipate keeping your fish for three years does not imply that you should buy your fish immediately. Male Betta Fish are usually only available for purchase in pet stores when they are approximately one year old. This is the stage at which their colours and ends have fully formed. Females are sold a little earlier than males, generally at approximately 6 months of age. 

Even though females tend to survive for a few more months than males, many prefer to retain males because of their beautiful colours. Because your fish is normally 6 months to 1-year old by the time you purchase it, you may anticipate him to survive for around two to two and a half years after purchase. 

Bettas, on the other hand, may survive for up to 4 or 5 years if they are provided with ideal tank conditions and are properly cared for and fed (more on this later).

How long do betta fish live in their natural habitat?

Bettas are found in shallow freshwater environments like ponds, streams, rice paddies, and canals in the wild. Because of human introduction, they have spread to other regions, including Singapore, Brazil, and Malaysia, where they were previously found only in Cambodia and Thailand. 

Betta Fish in the wild are thought to have a somewhat shorter life than those kept in captivity, according to popular belief. Due to the fact that the waters in which they dwell are not as carefully managed as the waters in a fish tank, they might get contaminated, which can kill food sources and plants, resulting in the fish’s lifetime being reduced significantly.

Men in the wild are also more likely to be exposed to other males than females. Siamese Fighting Fish are so named because they are extremely territorial and violent toward other fish who intrude into their territory. 

Increased exposure to other evils increases their likelihood of fighting, which raises their likelihood of dying sooner.

How to increase your betta’s lifespan?

After understanding how long betta fish live in tanks and in the natural habitat, we can begin to think about how we may extend their lives to the greatest extent possible. In reality, it is fairly easy, and by following all of the recommendations below, you will boost their chances of living a longer life while also improving the overall quality of their existence.

Make sure you buy a healthy betta

Purchase your fish from a well-known retailer. Avoid purchasing any fish that exhibits any of the following characteristics — these characteristics might signal that the fish hasn’t been properly cared for, and as a result, they may be stressed and less likely to live a long life.

·      Pale colour

·      Torn fins

·      Bulging eyes

·      Injuries or scars on their body

You should be looking for a fish that is any of the following:

·      Bright colour

·      Own clear bright eyes

·      Have reflective behaviours

Use a filter and a heater

It is a popular misconception that because Betta Fish live in rice fields in the wild, they can endure unheated, filthy water. This is not true. 

Because of Thailand’s environment, the water in your tank will naturally warm up, making it necessary to install a heater in your tank as well. They are used to temperatures ranging from 75 to 80 degrees Fahrenheit. 

It is also necessary to make use of a filter. They will not survive in water that is contaminated or unfiltered. A filter will clean the water by converting the ammonia and nitrite accumulation into less dangerous molecules, and it will also keep the water aerated, which is important for swimming. 

Even when using a filter, it is still necessary to do regular water changes to prevent the accumulation of nitrates.

Use plants to provide oxygen

The final piece of advice we have for establishing the greatest possible habitat for your Betta and, as a result, increasing their longevity, is to incorporate plants into your aquarium design. 

The advantages of keeping plants in your aquarium are not predicated on their nutritional value, as they are for other species. Because these fish are carnivorous, whatever nibble they get from the plant will be just that: a nibble. 

Living plants enhance the oxygen levels in your tank while also enriching the surrounding environment. It will also recreate their native surroundings, increasing the likelihood that you will witness their normal behaviour.
