I Agree with fish freek. I divide food into daily portions, and then refreeze it, and when it is time to feed, I drop a frozen food cube in an old shot glass with water, and wait till it softens up a bit before feeding.
I make my own frozen food and I put it into sandwith bags and I break off a chunk when I feed. The food smells so bad when its good its hard to tell when its really gone bad.

I keep the packs frozen and only pull out a pack/or cube, cut off the amount I want to feed and let it thaw in a cup of tank water and put the rest of the cube back in the pack and the freezer.
