Grzegorz, There is no study on apisto breeding & longevity. My personal experience is that my apistos females live about 50% than those in Uwe Römer's longevity experiment. His females were constantly breeding. Mine I breed only 3 - 4 times each year (I separate the males from the females after spawning). My feeling is that spawning & raising fry causes more stress than simply eating & swimming. Stress tends to "age" everyone by making us more susceptible to diseases, etc. Mike Wise Grzegorz Prusinowski wrote: > Hello folks, > > I'm a starting apisto maniac from Poland.
