Do some research, and you'll find out that it's prohibit to capture or sell wild Asian arowana everywhere in the world
It's prohibited? Really? That must mean it doesn't exist, because people never do things that are illegal...
Sigh...Ewurm is quite correct, there is a market for wild caught and poached animals. It is however, not advertised for everyone to see. These fish aren't chipped and can't be openly sold as the distribution of arowanas is regulated by the Indonesian agriculture agencies if I'm not mistaken...
Yes, they may not have the brightest color like farm raised stock, but imagine if you could wander down to your local river and scoop a few 24" Reds...and then sell 'em for a couple grand...
