The Wolf: In which case, no dilemma, IMO: assuming you can beleive what you're being told, then purchasing the fish does no harm. It's not depleting wild stocks of endangered animal, so, no issue...
Tokis: what are the "???" for...?
To clarify: most people who are serious about breeding endangered fish will have researched and made sure they have an appropriate set-up. I'm sure that in setting up and considering breeding them yourself, you've thought out the problems and come up with solutions.
However, if you compare that to someone who wants to keep rare Fish A and thinks along the lines of "ooh, well, i can always breed them and that will make it OK" it's fairly obvious that one is more likely to be successful and not end up with badly inbred fish than the other!!
