I had the chance to get one off craiglist last year- so I consulted a good friend of mine, whos advice on arowanas I respect very much- he advised me that its a fairly common defect and not worth the $100 price-but I really liked it, and still might have taken it, but then I found out it already had DE in both eyes at 10"! thats 2 too many defects for a $100 silver in my book-
yours looks awesome and if you do end up selling it, please put me on top of the list!
