wow, very good. I was about to get arowana, many years ago, I have booked 2 baby red arowana (3" each) for over HK$10000 with licensed. I did a lot of reasearch (before the internet time)and realise in the natural world, they will jump up and eat the insects on the tree branch above water, thats why they call 龍吐珠 then I have cancel the order, because this setup is difficult
