You know, contrary to popular belief, a well kept and colored (due to proper feeding) Silver arowanas can be just as prized as some of their asian cousins.
While I agree that a silver arowana is still a nice fish, I find that asian arowanas have more colour to them, which is the principle reason i select them over a silver.
Is it true too that asian arowanas get stouter body mass when they mature to full size? Because i personally have never seen a really stout bodied silver.
