very good point T1 i wonder how many will get really big too.
large tigers are few and far between and getting one too 12-15'' is a very long process taking quite a few years in the aquarium.
i would say same goes for wild fish what happens when the stocks run low, it takes approx 15 month to double the population but what if the same happens next year to them if the area they are from has the same problems ie the D pulcher.
it seems the IT's and others are really in abundance in the wild at present but things can change and i hope this does not change.
