What proof and evidence do you have that all silvers are wild caught?

It goes both ways. Without evidence it's all hearsay and speculation, not "stipulation" as you suggested. A stipulation is a condition, come on Neil, surely you know that
What proof? The simple fact they LIVE in the wild and breed there.. Also, for the past 40 years silvers have been bought into the hobby via collecting in SA.. Now, UNless you have real evidence that this collecting method no longer exists and arowana are all farm raised. Please, show us.. But dont give me that "Oh, well I think" crap. Because that is subjective opinion and we dont want it.
Also- I was discussing some DROA stuff with my GF at the time I was writing my last post. THat is where the "stipulation" problem came in, hehe.
No I have no certificate, because my fish is not farm raised, it was imported from South America to Spain. The cobra snakehead I have was imported from a farm in Asia, it's captive bred.
How do you know this? what is your proof? How do you know your fish was from SA? or Asia? Because the idiot on the phone who sold it to you, told you this?
When did I mention barca? What on earth are you on about? Barca have NEVER been bred - do you even know what a channa barca is? There are somewhere around 10 in captivity and ashdavid has 3 of them. 2 of them were imported to the UK by Tom Halvorsen, before being sold to ashdavid.
Tell me - given the mass breeding of Asian aros in Asia, why is it so hard to fathom that silver aros are also mass bred? And acestros and hydrolycus are not what I would consider common, at least not in England. Like I said, they both had to be ordered. The only place I've visited in the UK that stock them both routinely is Wildwoods, one of the best fish places in England.
It doesnt matter if asian arowana are being bred by the millions. Because those are a DIFFERENT fish. It is stupid to think- "well asian aros are being bred! So that must mean silvers and blacks are too!!! Because those asians love to breed everything!!"
The simple fact is, you have no proof, and untill you do. You shouldnt post.
In the average LFS in the US are you more likely to see a silver aro or a cuda or vamp tetra?
Freshwater cudas are more common then silvers, So are Vamp tettras.
