Posted on

How long do betta fish live is a common question among the betta fish enthusiasts. The average betta fish life span is 3 to 5 years. There are instances of a betta surviving for 9 years. But those are very exceptional instances. Bettas should do well for over 3 years. They are extremely hardy fish and will survive conditions that would kill other specie. However, the fact is that they wont thrive in those conditions.

Bettas are aggressive territorials. Obviously they are Siamese fighting fish. The male bettas are known to be very aggressive towards other bettas and will fight each other, to defend their territory, until the opponent gets seriously injured or killed. This aggressive nature is the reason for keeping the bettas single. Interestingly, bettas are generally not aggressive to other specie. They are found to be aggressive to fish with long, flashy fins and bright colors, mistaking them to be their betta competitors.

Fish like cories make good tank mates. They stay at the bottom of the tank and scavenge every bit of food that the betta misses. In doing so, they help to keep the tank clean. Do not feed the bettas often. It is sufficient to feed them once a day. Bettas are obligate carnivores. They love live food such as blood worms and brine shrimp. Fish pellets and flakes are better as they are much more balanced diet. Flakes are easier on the digestive system and can increase the betta fish life span.

Bettas must have access to the surface to breathe. They have a special organ called labyrinthe, which helps them to take oxygen directly from the atmosphere. The tanks should not be very deep as that would mean the bettas would have to waste their energy in swimming to the water surface to breathe. The water in the tank must be treated for presence of chlorine.

Bettas are tropical fish. They like water to be between 75 and 80 degrees Fahrenheit. At such temperatures,they are active and exhibit intense colors. Cold water can put a betta into shock and kill the fish. Bettas are used to slow moving currents. Presence of strong currents might stress them. Clean water and warm temperature can extend betta fish life span.

Ammonia levels are generally high in new tanks. This will kill or make the bettas sick. Wash the tanks regularly and at least once a week. The chemicals in soaps or detergents can harm the bettas. Instead, use warm water and wash cloth to get rid of the dirt and algae in the tanks. Bettas are beautiful hardy fish. They have tolerated bad environments and survived. But these unfriendly conditions have shortened the betta fish life span

The answer to the question, how long do the betta fish live, very much depends on us. By presenting a clean tank, warm clean water, we can extend the betta fish life span.

In captivity, male and female betta fish have a lifespan of 2-4 years. However, the lifespan of a betta fish is determined by a number of factors. The two most important factors are how old a betta is when you get it and how well it is cared for in captivity.

Instead of a pet or big box store, buy a betta from a local or online breeder like Aquabid. Male bettas are sold in these stores when they are about a year old, and female bettas are sold when they are about six months old. This will have an impact on how long you have them.

You must keep in mind that in many cases, they were raised in an environment that was extremely harmful to their health. Especially if you purchased them from a store that stores them in plastic cups. This can have a significant impact on their health and life.

If you’re wondering how long female bettas can live, they typically live a few months longer than males.

How long can betta fish go without food?

If you are an aquarium hobbyist, you are probably familiar with Betta fish. Betta fish, also known as Siamese fighting fish, are one of the most vibrant and attractive fish species found in almost every aquarium.

Betta fish are known to be carnivorous in the wild. Insect larvae, shrimp, small worms, and carrion are among their preferred foods. Those kept in captivity prefer flakes and live foods, among other things.

It is a well-known fact that aquarium fish require routine feeding. So what happens if you decide to leave your fish behind and go on a trip? This is a frequently asked question. Perhaps you’ll need to find someone to look after your fish while you’re gone. However, when it comes to Betta fish, you will no longer need to be concerned.

Thus, how long can your Betta fish survive without food? To your surprise, this fish species can survive for approximately two weeks (up to 14 days) without food…

However, you should not dwell on this information and should instead leave your Betta fish alone during that time period. At the very least, you can come up with a better solution that will enable your fish to go that long without food. Let’s learn more about what you should do when you’re not with your Betta fish.

How long can a betta fish live out of water?

Under ideal conditions – a humid climate, a non-absorbent surface, and a cool temperature – your fish can survive for up to 5-6 hours. In the worst-case scenario, with no humidity, an absorbent surface, and high temperatures, your betta’s survival for 30 minutes would be a miracle.

How long can betta fish live in cold water?

A betta can live up to five years in a fish tank with a temperature range of 65 to 70 degrees Fahrenheit or 18 to 21 degrees Celsius, but it is extremely susceptible to disease. What happens to betta fish when they are exposed to cold water? A newly acquired betta fish that is placed in cold water will not perish immediately.

How to tell how old a betta fish is?

Bettas, also known as Siamese fighting fish, are characterized by their vibrant colors and flowing fins. However, chances are you had no idea how old your betta was when you brought it home in a cup from a pet store. While determining the exact age of your betta is difficult, by applying some common sense and observing your fish, you may be able to make a very close estimate.

Determining Age with Features

  • Check the size of your betta. Bettas are typically around 3 inches (7.6 cm) in length as adults. Measure the length of your fish’s tank with a measuring tape. If your betta is smaller than the average, it is almost certainly a juvenile.
  • It can be challenging to precisely measure a betta. In most cases, simply holding a measuring tape against the glass will suffice to obtain an estimate. Be patient, as most healthy bettas do not remain still for long periods of time.
  • Examine the fins of your betta. Adult bettas have lovely, flowing fins. If your betta exhibits this trait, it is a good indication that it is an adult. If the fins are very small, it is either a juvenile or a baby. Ascertain that you are aware of your betta’s gender. Female bettas do not develop the long, flowing fins that males do. Contrast normal wear with disease-related injuries. Crowntails are born with torn-looking fins.
  • Evaluate your betta’s color. Bettas in their youth are vibrant, while those in their middle years are slightly faded. The color of an older betta’s scales will be slightly faded and muted.

Identifying Signs of Aging

  • Examine your fish’s body for changes. You may notice that your betta is becoming paler with each passing day, or that even with daily feeding, your fish is becoming skinnier. These are the telltale signs of an elderly betta.
  • Keep an eye out for changes in energy. When your betta reaches old age, it will flare with much less vigour than it used to. After a certain number of years, many bettas lose their desire to flare. Additionally, while an adult betta swims vigorously in its tank, older bettas hide behind plants and décor and swim slowly. While feeding your betta, keep an eye on how quickly it recognizes its food. Bettas that are older may swim slowly to their food and may miss it a few times before spotting it.
  • Examine the betta’s eyes for cataracts. Cataracts, or filmy or hazy spots inside the eye, are common in older bettas. This is normal for older bettas and will occur regardless of the size of the tank or how clean the water is kept.

What Should You Feed Your Betta Fish?

Bettas are a few different species of fish with upturned mouths. This means they feed directly on the surface of the water. They subsist primarily on brine shrimp, daphnia, and dried blood worms.

This fish can occasionally become picky about what they eat, but they prefer to eat food that is floating on the surface rather than on the substrate or at the bottom of the tank. Most importantly, provide them with protein-rich foods, as Bettas are naturally carnivorous fish.

Never believe the stories about Bettas surviving on plant roots. All of these are baseless allegations and embellished stories about this tank fish’s feeding habits.

The majority of aquarium hobbyists choose to feed their Betta fish pellets due to their simplicity and effectiveness. Pellets are less messy and contain a high concentration of protein, which your fish require to thrive. Additionally, you can supplement their diets with a few live and frozen foods as a special treat during their feeding routine.

Maintaining the Health of Your Betta Fish While You Are Away

The following simple tips will assist you in maintaining the health of your Betta fish while you are away for an extended period of time:

  • Fish, by definition, are cold-blooded. This indicates that their metabolism is highly dependent on their immediate environment. Fish kept in warmer areas require more feeding than those kept in colder environments. Due to the fact that Bettas are tropical fish that cannot survive in a colder environment, you should ensure that their tank environment is conducive to their survival if left alone.
  • Maintaining the health of your Betta fish should be your primary concern. In other words, you must maintain a constant tropical tank water temperature for them. Additionally, the temperature should range from 76 to 78 degrees Fahrenheit. If the water is too cold or too hot, it can stress your fish or even kill them, as this is not the optimal environment for their survival. Additionally, temperature has an effect on how your fish feed. Low temperatures alter your fish’s feeding habits by causing them to become slightly lethargic, resulting in them consuming less. Warm temperatures, on the other hand, can increase their metabolic rate and cause them to consume more food. It is recommended to keep the temperature in the area where your fish live between 71 and 73 degrees Fahrenheit for optimal food consumption.
  • If you anticipate being gone for longer than four days, it’s a good idea to perform a 50 to 100 percent water change prior to leaving for your vacation and upon your return. In any case, this formula is highly dependent on the tank’s size. As a result, it may vary slightly depending on the capacity of your tank. Changing the water frequently is critical for keeping your fish safe and comfortable in its environment. When your Bettas breathe, they excrete ammonia and food remnants into the tank water. If you do not take immediate action, you risk exposing your fish to an unfavorable tank environment.
  • When leaving your Bettas for an extended period of time, the importance of a proper aquarium size combined with ideal tank conditions should be one of the first considerations. Your fish will thrive more in a well-maintained tank than they will in unfiltered tank water where the conditions are, to put it mildly, extreme.
  • You can safely relocate your fish to a larger tank and leave for an extended period of time without fear of their survival. A larger tank provides the most secure environment for your fish to swim in and hide when necessary. Additionally, you should ensure that your tank has a lid with holes to provide oxygen to your fish during your absence.
  • Provide your fish with the same day and night conditions as humans. This can be accomplished by ensuring that your tank receives an equal amount of direct sunlight and darkness, which will keep your fish active or allow them to rest when necessary.
  • If you have automatic fish feeders in your tank, turn them off while you are away. These devices have the potential to overfeed your fish, resulting in food waste. Additionally, the devices frequently fail, making them unsuitable for use in your absence.
  • Bettas can survive for up to two weeks without food, although this is not recommended. Anything longer than six days will force your fish to begin depleting their reserves, which will eventually result in starvation. As a result, the recommended time period for leaving your fish without food is four to five days.
  • Before you leave your fish without food, you should check on their health. Sick or weak fish cannot survive for an extended period of time without food. As such, take your time and inspect your fish to ensure they can survive nearly two weeks without food while you’re away.

The best way to keep your Bettas healthy and strong is to maintain a tank environment that is conducive to their survival. To begin, the water should be heated to a temperature of between 76 and 78 degrees Fahrenheit. Never allow your tank water to become extremely cold or extremely hot, as this will stress or kill your fish.

How to Increase the Lifespan of Your Betta Fish

Betta fish are tropical freshwater fish that come in a variety of colors and shapes. Their average life expectancy of is three years. The following factors will affect your Betta Fish’s life expectancy:

  • If you keep your Bettas in the proper tank conditions, they can live a longer life. Ascertain that the water in your aquarium is clean and contains all of the necessary parameters.
  • Male Bettas are distributed at one year of age. This is the time of year when their colors and fins are most noticeable. Females, on the other hand, are sold at six months of age and have a slightly longer life expectancy than males. However, male Bettas are preferred by the majority of aquarists due to their vibrancy and attractiveness.
  • When selecting Betta fish for your aquarium, look for those that are robust and healthy. Above all, you should purchase your fish from a reputable fish store. If you notice any of the following characteristics in certain fish, do not purchase them: Fins that have been ripped Discoloration of the skin, Bruised body, Prominent eyes
  • Consider those Bettas that are vibrant and have crystal clear eyes.
  • Ascertain that the Betta fish you choose has the fastest response time possible.

Final Remarks

Betta fish are among the most stunning and vibrant aquarium fish you’re likely to encounter in an aquarium setup. These tropical freshwater fish are aggressive and prefer to feed on the surface. Given the hardiness of Bettas, you can leave them without food for a maximum of five days while on vacation.

These fish can go up to 14 days (two weeks) without eating, but it is not recommended to let them go that long without eating unless you want to risk losing them. If you intend to leave your Bettas at home for a short period of time, ensure that their tank conditions are favorable for their survival.
