No cheaper than KensFish. There's Kens and then there's all-the-others in 2nd place as far as price. Kens has such a huge variety, too. That's what I like. You can switch your fish's food around and still get it all for the same great price.
there was one other site, but i believe they were mostly flakes, and were about the same price as kens.
order from kensfish.com. you wont be dissapointed if you order there. just dont order the no-carb pellets, myself and other members had several fish that refused it over and over.
Your Aro won't eat food unless it's shaped in sticks? Just kidding Seriously though-look at the ingredients in those "Aro Sticks" and compare to ingredients in some of the stuff Ken's sells. I can almost guarrantee you'll find the exact same (& better) ingredients in some of the stuff he sells except it's not shaped into sticks (or maybe it is cuz he sells sticks, too).
