I've known them to live for less than 18 months here in total, dependent on frequency of breeding and temperature. If you purchase adult pairs of Caca's you may be lucky to get 6 months out of them, but at the moment I'm sat with a Killi expert who keeps his fish room at lower temperatures than many of us would think appropriate, and yet he breeds more A. nijsseni than anyone I know, and has males which have reached 3.5 years old. At these lower temps he's had Caca's for 3 years, so it doesn't always apply.
