For the life of me, I can't figure this out. No matter what online resource I check with, it's always suggested that sinking pellets be fed to fancies and goldies, in general, instead of flakes. I have always fed the Omega One Goldfish Flakes to my fancies in the past, and when I attempted to introduce the New Life Spectrum Goldfish Pellets, the fish never really took to them...in fact, it made them downright lethargic after they attempted to digest them.
Fast-forward to today and my new setup: I went to the local Petco just now to pick up fresh API test solutions and a bottle of the NLS pellets (I already began feeding my two new inhabitants the Omega One flakes, which they seem to love), and when I attempted to feed the new pellets, the same thing happened with these new guys -- they started eating them as they fell from the surface, but they're acting weird now, staying on the bottom and moving their mouths as if they can't really digest them or something. They DON'T behave like this with flakes.
What is the deal with these pellets? Are they as good as their reputation makes them out to be? Is it normal for the fish to behave as if they're "bloated" and "full" after eating them?
As a matter of reference, here's what I picked up:
