i can't imagine someone an imported fish would sell for under $10 bucks...so i think that's right. Costs of shipping, govt standards, customs and the whole lot...
So, I agree with the doc, at prices like these its hard to believe anything such as that would be imported...no matter what the vendor says. They are most likely domestic.
And some sneaky vendors like to say their fish are imported because perhaps the parents could have been japanese, but the offspring are all domestic... a nasty gimmick for sure.
And imported can mean anything outside of the US, so someone can be breeding fish in thailand and shipping 'em here and that would be considered "imported,"
So, as doc says, If someone is saying imported. As for the bill of lading or customs docs as proof.
