which fish live for long time2007-11-24 23:43:01Answers:

Generally, the larger the fish the longer the life span. Those with slower growth rates also tend to have longer life spans.

Most smaller aquarium fish last less than 10 years.

Many mid sized/larger aquarium fish can live between 10 to 20 years.

There are always exceptions however.

examples -

-goldfish 30+ years

-clown loaches i hear can reach 50.. I'll tell you in 50 years if mine is still alive

-bloodfin tetra are small but can live past 10 years

Sturgeons have very long lifespans, and have been known to live in excess of 100 years. However, they may be beaten by certain kinds of carp; there is a report of a koi (a japanese carp) named Hanako who lived to the age of 226, making her the oldest fish and possibly the oldest animal ever known, if the report is true. At any rate, it is known that carp can have very long lifespans.

I've had a black moor for the past seven years, and he's still going strong. The main key to a long-lived fish is taking care of it. Change the water at least once a month, don't feed it too much, keep a good water temperature, and have a good filter.

Most fish have a fairly decent life span, as long as they are in idea condtions!

stugeons can live up to more than 100 years but are quite hard to take care of. clown loaches live to about 40 and oscars are also long lived. bichirs can live up to 40+ years and so would anglefish. koi fish have the longest recorded life span, tho.

The life span of a fish depends greatly on it's size. Small species, with a high metabolic rate, use up the same number of heartbeats faster than larger animals with slower heartbeats. The general rule is the heart is designed to beat only a limited number of times. Larger fish will tend to live longer lives than smaller ones. Smaller common freshwater livebearers live for two to three years, and gouramis three to four years. Larger catfish, calico sharks and some cichlids can live up to eight to ten years.
