My friend had one. He got it from a friend of his that worked at the wholesaler. It was a very nice fish. It did have a protruding lower jaw. It's a much slower growing/slender fish and doesn't have the drop eye like the silvers. It was solid pearl white metallic. Yes, he managed to kill it about 2 years ago at about 24". It suddenly quite eating and went down hill.
Platinum Black Aro look different from Platinum Silver Aro.
