As with other small aquarium fish, people often assume that the lifespan of the betta fish is rather short, and that their fish will only survive for a year or two. But is this true? How long do betta fish live?
In this article, we will discuss how long betta fish live for on average, plus factors that can influence the health and lifespan of your fish.
How long do betta fish live?
Kept within a suitable environment, a healthy betta fish of either sex can be expected to live for at least three years. In some cases, however, owners have reported betta fish living for as long as ten years within their tank, though this is quite rare!
How you care for your fish, accommodate for their needs and keep them safe from predators will dictate how long your own betta is likely to live.
The danger of fighting
One of the biggest risks to the health and longevity of the male betta is their tendency to fight with other males! This is of course how they acquired the name “Siamese fighting fish.”
Unless you keep a really large aquarium with plenty of room for different territories, it is strongly discouraged to keep more than one male betta together. Injuries, infections and other side effects of fighting can all shorten the lifespan of your bettas, and in some cases, two territorial males will fight to the death.
In addition to this, the bright colors of the betta and their long, trailing fins and tails will make them a target for some other breeds of fish, who may nip at their fins and chase after them.
Other factors that affect how long betta fish live
The tank conditions and living environment of your fish will of course contribute to how long they live. As with any other fish, it is important to provide enough room in the tank for all of your fish and ensure that the filtration is adequate and the water quality suitable for their needs.
Bettas also need to be fed an appropriate diet. You can find betta-specific fish food offered for sale in larger aquarium retailers and online.
All of this will help to ensure that your betta stays fit and healthy, and lives to a good old age.
