It's not an arowana at all. I knew that when I saw the voting.
What I want to know, is honestly who has an arapaima in an aquarium on the boards. Of course I'll have to wait, but honestly you need a 1000 gallon tank for them. They get HUGE. I'm suspicious if that's a real picture from someone's aquarium on the forum or if it was pulled off the internet. Of course I mean no offense or am judging against it. I just have a hard time believing it.
