The person selling this says it's a good specimen, but I am not that knowledgeable when it comes to arowana grades and quality. Hence wanted check what it could be worth, the asking price is nearly 500usd.
That price seems fair if not good value imho (if again it's healthy and robust upon subsequent viewing); comparatively a mostly crossed (6th level) BBXB with cert from a good farm will go for about US$1,000-$1,200+ nowadays.
