To the manufacturer's credit, they do have a date on the bottom of the package. It was sealed with foil, but it came off fairly quickly and I wonder if this was loose. The age of the product may relate to why some of the fussier fish haven't fallen all over themselves taking some of these flakes. On the other hand, we're not "cheating" and using a taste attractant with it.

Maybe I should try to get some garlic in solution and soak a couple of these flakes in it. In a week or so they will be used up anyway.

However those livebearers who shamelessly devour anything, really chow it down. Even a new pair of killies from the African Savanna (being baby-sat) do a pretty good job of taking it.

I'm trying to use up samples and other purchased foods before buying any others. It simply isn't fair to feed antique flake foods to the fish. :)

Budgie, this sample of one does suggest that other foods may be taken more enthusiastically. On the other hand, one should test feed products produced at about the same time. Different fishes will be attracted to different foods too.
