I am sorry this happened to you. I recently moved from the New Orleans area to start a PhD in Zoology at Michigan State University. Let me tell you the whole story of this fish. A few of them came in to a LFS that deals in rare predators. They were white when they came in, but were not labeled as platinum from the distributor or from the LFS. They were priced for about 150, not sure what was actually paid for them, buyer likes to haggle. He then turned around and put them up for sale as "Platinum Jardinis." I am sorry that this happened to you. I hope that he comes to his senses and does the right thing. The seller does import and resell on a regular basis, but this was not one of those times.
On a separate note, the tank is very cool. I would love to see some more videos of it.
