I've kept Africans (Malawian mbuna) for several years now but have never kept any of them long enough to have one die of "natural causes" AFAIK
. My current tank was started slightly over a year ago and I still have virtually every one of my original stock. They were all introduced as small juveniles and are now reaching maturity. My question is: what is the natural lifespan of most Malawian mbuna? I know that most species don't reach full size for several years but I have no idea what their average lifespan is. Thanks!
