i was considering doing this as well just one prob for me is that one bag would last forever!!! the nutrients are "garunteed" 
i really don't see why they couldn't "compete" with hikari...
by compete i mean see same results growth, color.....
i only saw floating catfish pellets...i'll check another feed store for the others
my aro eats the large floating pelets by hakari only b/c i ordered in bulk and i've got 3bags left.....this is a good link for ordering food at discounted prices!!!
