Jackpot Fish? (Acanthurus Tang cross?)
I have emailed you before about my Horn Shark tank still going really good after 8 months ( grown a good 4 inches! ) and he is over three feet.
He eats really well shows good color. 
<Ahh, glad to read of your success>
I also asked you a lot of questions about my angelfish tank 800 gallons which after a long drawn out series of events was taking down and the contents were auctioned off. Its back to reef the and my other reef tank of 600 gallons is gone. All are doing great. In my sons room we have a 75 gal fish only for a total of three tanks in the house. He has three fish in there that have lived for over a year as of Dec 29. A Koran Angelfish, Huma Trigger, and Tang of some sort. All are 4 inches. The tang was sold to us as a misc. ocean tang. I thought it was a Gold Rimmed (nigricans) but it just never looked quite like my id pictures. 
<Please take a look through the many images of tangs posted on WetWebMedia.com>
Recently, I was searching for some fish at www.themarinecenter.com and I came across what's being sold as a cross between the Gold Rim and an Achilles hybrid.
<Yes, this "happens">
The picture is exact to what I had. Like identical. Our fish was sold for $24.99,
<Bargain, considering "what it takes" to collect, hold, ship... such a live animal>
about how much is it worth? What exactly is it? It eats everything, big algae eater too. Any help again appreciated.
