Seeing as we seem to be running with it, I assumed the "what was illegally transported" remark was a joke. It seems unlikely unless I'm missing something that this is how that stuff came in.
I know the aquarium in Dallas gets pretty grumpy about people trying to call them to take their oscars that outgrow their tanks, stray stuff, etc. Not sure if they have any connection to customs there though. It really is a crummy situation when something gets caught smuggled in as Customs isn't exactly a group of reefkeeping experts, nor could they be from a practical perspective even if they were so inclined.
