Wes I once offered hooking you up with some wels breeders, are you still interested, because you could get 4" albino wels for 10 dollars and 2 feet normals for 50.. + shipping. You'ld have to care about all the shipping though, and I'm not sure if they'd really do it.
yes, the problem is like you said is to find someone to ship them to me, and at the small amount, lets say I get 30 fish x10 that would be $300.00 but shipping for a box plus fish and wildlife inspection fees, shipping, time, and then my effort and profit, it just wouldn't be worth it. that is probably why this fish has rarely been offered in the US in the past, almost non, I only know of one occasion by a few private hobbyists.
the same is like peacock bass are food fish in Brazil, diamond leopoldi were pests and killed by fisherman in Brazil and command tens of thousands in the US.
