well, from what i know mate, breeding wise, a few people have done it, the same way as you can get any of this sp. family to breed, but no one has managed to either hatch or keep alive the fry. id imagine another inch/half an inch, and theyll def. be sexually mature (although they may be now at 4.5"). anyhow, you gotta think how to keep your fry alive if you manage it, as this looks like its the problem
