Regarding the above poster who says the food is pre-ground: I is not supposed to be pre-ground. It is supposed to be 1/4" flakes. My LFS just sent 2 cases of it (read: dust) back to the manufacturer. At least I got my money back!
This is the most crumbly, dustiest flake food I've seen yet. At first I thought that the can may have been shipped or stored upside-down because when I opened the can it looked like what you normally see at the bottom of a can of flake food. However, I dumped the can into a bowl and saw that the entire can was like that! It is very very dry and has only a faint, stale odor as opposed to Omega One’s nice dead fish smell.
My fish seemed to like it enough, but as soon as the food hit the surface, it formed a CLOUD of dust in the water. It kept them busy for about 15 minutes, chasing all over the tank to try and suck up a bit of dust here and there.
