Betta Fish normally live between two and four years. Although, if one cares really well about them, some of them reach five, or even seven years. Few Betta Fish according to rumour, managed to live around ten years.
The lifetime of them really depends on factors like genetics, quality of the breeding and the care that they receive.
How Long Do Betta Fish Live?
Almost all Betta Fish that one sells in stores for pets already have six months to one year when one buys them. Assumed, babies in those stores usually are around four months old. So the fish maybe already is halfway in his life, before it arrives to new home.
Some Betta Fish from stores can be even two years old, what implies that they will not live much more after the purchase.
Rating of the precise Age of Betta Fish is really very difficult. One way to approximate it is observe the size. Adult Betta Fish measure around three inches of length, with long and flowing fins.
Young fishes look more small, with fins shorter. Old Betta Fish commonly move less, their colours become a bit darker, and they hardly find their food. Some older Betta Fish lose colour on the face, that turns to pale grey near the gills.
Even so, size of teh fins alone do not suffice to faithfully determine the Age.
Betta Fish bad bred from big chain stores for pets commonly do not reach long life. Genetics play a lead hear. Fishes from good breeders can live seven to nine years, if one cares properly.
While that, Betta Fish in little bowls rare pass eighteen months to two years. One can keep Betta Fish in more spacious tanks, that allows them to live more than seven or eight years.
Bad quality of the water can badly shorten the lifetime of Betta Fish. PH of 7.0, that is neutral, works best for them. Although Betta Fish tolerate low levels of oxygen thanks to their labyrinth organ, wrong conditions in water push them vulnerable to diseases like rot of fins and loss of scales.
It is knowingly best to use at least five gallons of water for Betta Fish, instead of little bowls or one-gallon tanks.
Cool water slows the metabolism of Betta Fish, what can help them Age more slowly. But water full of ammonia, without proper minerals, weaken their immune system and cause problems like rot of fins. So cool water alone do not ensure long life.
Four years is considered old for Betta Fish. Around five to six years are typical for old Age, although most pet Betta Fish die sooner because of bad conditions in stores. One Betta Fish, according to rumour, lived more than three years and yet seemed nearly energeticfish of middle years, before it caught disease from a friend in ill tank.
