Black rays only come from the Xingu river system in central Brazil, FAR from Peru. Like Miles said, if this was legit and the rays were farm raised in Peru they would go to Asia and sell for double what they could get here.
Why your at it bring in those $1200 armatus. If you don't know anything about rays and there are many many people here that are very knowledgeable on the subject why argue?
In case you can get some fish as a basement importer that big time experienced importers cant get for some odd reason I will take two!
