Both of mine are picky. It took me FOREVER to find a pellet that my female likes because she only would eat flakes. My male, only likes the small pellets by Hagen (he has a small mouth). He refuses any other type of food, and will actually sulk if you try to give him something other than those pellets. He doesn't even like bloodworms. This summer, when we have fruit flies again, I'll try to catch a few and see if he'll eat those. My female LOVES fruit flies and almost took her life chasing after one.
