I know but somehow arowanas can taste the difference.
I know this because my silver arowanas will not eat cichlid pellets at all and eats the sticks everyday.
My jardini no longer accepts cichlid pellets and only eats the sticks as well.
May be a difference and good for the ultra picky arowanas, myself I would just convert to the cichlid gold instead of paying three times the price for the jumbos.
