I have heard records of them living past 15. Is this possible for the little things, and if so, how do people keep them alive that long? I have never kept kuhlis, though I do plan on keeping them somewhere down the line, and I'd like to have them for as long as possible (more for the sake of not needing to replace a naturally short lived fish often, especially because the pangio kuhli I like are hard to breed in captivity reliably)
