Maybe it's just me, but that picture definitely doesn't look flattering. If I was looking for a 300 gallon type fish I'd go with a Sohal. More aggressive, but vibrant colors at half the price. Even more likely a Vlamingi.
I want a Sohal also but just scared it might whoop all my other fish! Lol
I'd be worried it would bite and scratch me.
I just bought one yesterday for $78
