ATM, I am convinced they are never, perhaps barring the rarest of accidents, imported into the US and EU.
Perhaps, the few that we have seen (IIRC Enrico from Germany has one) were a special order, which, again, is tricky because relying on the locals who catch them for the ID is not a good way to go. Those TSNs look so similar when young and the local fishermen and the catchers of fish for ornamental trade are not educated in the fine things of the ID process and often are simply uneducated. They know how to catch a fish for food. The exporters are most often too. From there, the ignorance propagates all the way to the end consumer.
As stated before, all we see in the US and EU are fasciatum by far and large (perhaps, in a big part because it is farmed... to make the fasciatum x RTC hybrid), rarely tigrinum, and even more rare reticulatum.
Wednesday, Necro, and Arapaimag (and BigRich and Ted from anythingfish?) are the three I'd heed on this topic but I am sure there are others.
