Things in that picture do look like meat patties. I can'f fool you guys. That is probably why the fish like them so well. The ones on the bottom look as if they have a glaze on them which is maybe stuff they spray on the pellets after they are extruded. I've read that manufacturers will spray heat sensitive oils and vitamins on the pellets after they come out of the extruder. Not sure if Purina does this to the AM pellets.
Now to put this discussion to rest, I received this from Bob Wucher at Purina Mills, District Manager, Livestock & Pet Specialist, who attended the PBoss V conference: ""They are filled with air but are not air tight so water will be absorbed into the pellet over time. As the water displaces the air they do become less buoyant and start to sink. Hope this helps."" Thanks a lot Bob, it did help my argument in the discussion. I hope my friend Cecil is not mad at me for winning this debate.
