But the pools evaporate in the dry season with some drying up completely. This annual cycle of birth and death means that Killifish complete their whole lifecycle in just one year, so if you buy an adult annual Killifish like the gorgeous Nothobranchius rachovii, it may not live for longer than a few months in your tank. Next are the nano fish species. So many small tropical fish can also complete their life cycle in just one year in the wild through having to.
In the space of a year, they can hatch, grow, mature, find a mate and breed, and pass on their DNA to future generations before something causes their premature death. Cardinal tetras may live for four or five years in a home tank, whereas they are considered annuals in the Rio Negro in Brazil. Medium-sized fish species like Gouramis and Angelfish can live for five to 10 years in captivity, provided water quality and diet are good, and stress levels are low. Catfish are particularly long-lived for fish and even Corydoras may live for 10 years or more.
Synodontis catfish can live for 25 years, so consider carefully before purchasing them as they will need a forever home. Most large cichlids like Oscars can live for years so again plan for if you will be able to provide a large aquarium and all the associated costs for the next 20 years. Do you intend to move house? Will you want a sofa there one day? Are other pets or children on the horizon? How much will it cost for electricity and food? I have two that I have had for 17 years bought in a third one died a few years back at around Interestingly, I had to separate them a few months back after all those years living relatively peacefully together.
I think some Cories can live longer than many think they do. I had two Pandas that I bought in that I am fairly certain lived for 14 years.
I still have three of their offspring living on in the same community tank. Save my name, email, and website in this browser for the next time I comment. By using this form you agree with the storage and handling of your data by this website.
Sign in. They generally only live for a bit more than two years. Bettas are not far behind. There have been documented cases of bettas living five years or more, but that is not the norm.
Livebearing fish such as mollies , platys, and swordtails generally live less than five years. Goldfish are on the other end of the lifespan spectrum. There are many documented cases of goldfish living a quarter of a century.
They are perhaps the best example of how poor habitat and care shortens the lifespan of aquarium fish. The majority of goldfish are not properly cared for and as a result, live only a few years.
Other fish that live longer include loaches, such as the clown loach and weather loach , which often live 10 to 15 years. Silver dollars and pacus also live 10 years or more, and the ever-popular convict cichlid can live for more than 10 years as well. It depends on a variety of factors, including how much attention you give them, the quality of their water , the aggressiveness of other fish in the tank, the type of food you give them, and the cleanliness of the fish tank.
The fish with the shortest lifespan is known to be the killifish, which only lives about a year, but many fish live upwards of 10 to 15 years, with the average being about 7. Following is the average lifespan of common aquarium fish based on a variety of sources.
