I have seen only two made. I used to work for the mad man that was behind the idea. They were never ment to be a salt water display piece, but more of a showcase of the fabrication skills. He got out of the tank business due to a business deal that went bad. Great guy, and I still have contact with him from time to time. I would keep that tank, because of all the pictures that were taken and all the magazines that it was in. Kinda famous. Good luck, Jason
