For those who are curious, it was collected from cayenne river in Guyana. Very unique pattern, new to me as well. It was brought in at 70cm, just over two feet and has since grown 16cm in a tank that's not that big at all. 160x80x70 which means it's grown longer than the width of the tank. Amazing... Housed alone.
I'll ask him tmr, I've seen him post about it since early last year so just under a year and half I suppose. Its going price is just about 8k usd actually which isn't unreasonable which I'm sure many on MFK here would agree with. It will take so many years to get to this size.
