It seems to me like this stuff would be best off as a supplement or something to use in a pinch. I believe you're best off feeding your Pacs/Pyxies whole animal prey, whether it's bugs or vertebrates. In addition the fish meal, dried potato products, and wheat gluten struck me as being really unnatural-you kinda have to figure the only plant matter they'd ingest in a wild setting is either predigested by their prey to some extent, OR something they'd accidentally swallow along with a prey item. That's just my opinion though. I hope this helps!
