Very very interesting Patrick :)

Actually, I'll take the conservation note a step further (not a lecture, but
more of a reminder :) and ask that we never reintroduce captive specimens to
open systems anywhere. A farm pond without any outlet is one thing (warn
the owner you there's a miniscule chance that you're going to hose his pond
heh), but an open stream might just give the opportunity for an aquarist to
wipe out one of these species (as we've just established :) with some type
of pathogen. I don't think anyone wants that kind of blood on their hands
when talking to St. Peter at the Pearly Gates ;)

What I'm getting at is... Don't take what you're not planning to keep for
the lifetime of that animal... And if something comes up where you have to
get rid of them, find another home (aquarists, shops, zoos, etc) or
euthenize the specimen. I find that by telling myself "I will have to kill
this animal if I can't care for it any longer" when collecting puts a lot of
fish right back into the water and avoids the whole unpleasantness down the
road :)

With that said... Back to this interesting discussion! :)
