There are reasons for these being only wild caught I'm no expert but AFAIK no one in the world is breeding ATF of any kindLOL...well you never know. I'm currently working towards breeding the Red Tail Barracuda (A. Falcatus). Also working with breeding Cichla Intermedia at the moment. The Tiger Fish might be on my list, perhaps only with the species that grows the smallest at adult size.
If it's breeding behavior is anything similar to the Barracuda, then there is always a possibility as long as you have a large tank.
