Average Life Span of A Tankfish

Average Lifespan of A Tank Fish

Introduction

Having an aquarium at your home will elevate your mood, and as time passes! And as the tank mates slowly become a part of your family. You may wonder what will be the Average Life Life span of Tank Fishes or your Aquarium fishes. The Average Life Expectancy of Aquarium fishes differs just like the average life expectancy of humans. Some fishes may live for only a few years, and some aquarium fishes can live long up to several decades. Smaller fishes usually live a shorter life span compared to bigger fishes.  Also, Fishes that lay eggs tend to live more compared to fishes that give birth to their young ones. The two most popular fishes of the aquarium, Betta and Gold Fishes, can be compared for this. Bettas usually live only up to 2 – 2.5 years, and Goldfishes, when taken good care of, can live up to several decades. You may have won a goldfish as a prize by participating in summer fairs, and within months, the fish would have died. This makes people usually think that fishes can survive only up to several months or maybe a year. But, all these happen only due to lack of fish keeping and poor maintenance. If taken care of and maintained properly, all aquatic and tank fishes can be grown for years down the lane. This blog will talk about the average age of these fishes and How some fishes lived for even several decades in great care.  We will also help you with how to take care of your cute little mates if you are completely new to fish keeping and petting. So, sit back, relax and enjoy the blog!

Short Lifespan Fishes

Anger reduces lifespan, say our ancestors. And to our surprise, it is applicable to fishes too. Most tempered fish have a short life span. Kill Fishes are the fishes within The Shortest Longevity with a lifespan of a maximum of 2 years. Bettas too are capable of living only two years, even in great conditions. Live-bearing fishes usually live for less than five years of age. Some examples are mollies, Swordfishes and Plates.

Long Lifespan Fishes

Our all-time favourite Goldfishes top the list when it comes to both calmness and longevity. They can live up to 20 to 25 years on great care and good maintenance. But, on poor care and maintenance, Goldfishes too can survive only a few years. Loaches like Clown Loach and Weather Loach can live up to 15 years. Convict Cichlid can live up to 20 years, and silver dollars can live till 10 years. There is even a history of a goldfish living till the age of 45 in most care and maintenance. So, this shows us how caring and maintenance plays a major role in your fishes’ health and lifespan. We have listed some of the records of the oldest fishes lived and their variety as follows.

Sharky is a White Goldfish with a fighter attitude. Paul Palmer won Sharky in a local fair, and his sister, too, won another fish.

Bob

The only player on the list who went to a $250 surgery at the age of 20 to remove his lumps was Bob. He was successfully treated by doctors and recovered quickly. These were some of the exceptional lifetimes of Goldfishes. But usually, fishes don’t live up to decades. They have a relatively short span of a lifetime. Let us see the average lifespan of different varieties of fishes in aquariums.

Average Lifespan of Aquarium Fish

The average lifespan of Aquarium fishes is unpredictable, just like the average lifespan of humans. Various factors affect the lifespan of tank fishes. Like said prior, small fishes live a shorter life span compared to long fishes. Egg-laying fishes have more life expectancy compared to fishes giving birth to their offsprings. The average life span of any tank fish variety can range between 2- 5 years. Small, Active, and angry fishes like Bettas and Kill fishes live 2 years maximum. Calmer fishes tend to live longer. So, we guess it is a calmness that can help live a longer life for both fishes and humans. Gold Fishes can live long with a comfortable life period. When taken good care of and kept under good maintenance, they can live even for decades like Goldie and Sharky. Things that kelp fishes to live longer are
  • Greater and broader tank capacity
  • Good water quality
  • Adequate nutrition
  • Lighting and heating of tank (if needed)
Now let us see the ways to improve the health and lifespan of your cute little tank mates.

How to Improve the Lifespan of Tank Fishes?

Fishes usually die so soon because of a lack of knowledge about the requirements of that species. So, Fish keepers must give a simple study on what species they are about to grow, about the water quality, lighting, and food needed by the fish. Ignorance to teach yourself is the reason why most of your fishes may die sooner in your aquarium. So, if you are wondering whether to add Goldfish or a Betta to your aquarium, perform a study and then plan on buying the needed. Buying the right tank also plays an important role. Make sure you are buying tanks and fishes from a reputable seller or online.  It is better to buy healthy fish initially, rather than buy a sick fish and treat it.  Apart from tank size and nutrition,
  • Water Temperature
  • Water pH
  • Hardness
  • Cleanliness
  • Tank plants
These criteria play a role in your fishes’ health and mood. Some tips to improve the lifespan of your pet fish are

Provide a bigger and better tank

Extra room is loved by every species on Earth. So, why not provide your cute pets with a bigger and better tank from initial stages. As a rule of thumb, it is advised to have one gallon extra for every inch your fish grows.  So, it is better to start with a minimum of 5 gallon tanks for your aquariums.

Try to Reduce Stress

Stress can be caused by various factors like
  • Stream Speed
  • No Inmates fighting for territory
  • Decorations inside the tank. 
So, Perform a study on what sort of stream speed, flooring, plants, and decorations are proffered by your species type and plan accordingly.  It is also better to have fewer inmates to reduce fighting for territorial dominations.  For Bettas, for God’s sake doesn’t even consider adding another fish inside the tank as an inmate.

Buy and Use Quality Tank Equipments

All equipment, including the tank, must be purchased of higher quality. This will help you with fewer problems in the long run.  It is also necessary to take care of the water once after filling. It is better advised to set up a 3-stage filtration system to eliminate all solid and dissolved waste in the water. You may also Add Lighting depending on your fish being Photo-philic or Photo-Phobic.  Adding A Tank Heater will help fish to be warm and cozy. Whatever equipment you buy from the store without taking proper care there is no way to safeguard it. Know more about cleaning the fish tank and it’s equipment through our posts. 

Test and Change Water Regularly

Test your tank water for pH and Salinity and once a week, it is good to change 10-25% of the water with fresh water.

Buy Good Quality Food

 It is much needed to provide your fishes with food that is highly neutral to keep them healthy. Add plant-herbivore-related products if your fish is an herbivore. You can give a party by feeding
  • Brines
  • Shrimps
  • Mealworms
  • Feeder fish to your pets who are omnivores or carnivores.
Adding some live plants will definitely help reduce the dissolved CO2 in water and improve dissolved O2. This makes breathing easier and less stressful for your fishes, enlightening their moods and showing off great health.

Conclusion

In fact, it is more of an art than a hobby.  Growing your fish for a longer time requires more attention, but can be done easily in a time course. Once you love the process, you will enjoy every bit done, and seeing them grow along with you is the biggest gift that fish keeping and growing can afford you.
