Actually, the rumor of how the "tip off" occurred goes something like this:
Someone had customers in Japan and Tawaiian that wanted the Clarions. This guy hadn't purchased the fish yet (I think he's a jobber), but he went to Fish and Wildlife to see what type of permits would be required to export the Clarions. I guess F&W didn't recall ever seeing any permits for Clarions to enter the US and got suspicious.
