starve them for a few days to a week....I know mine love dried Krill/Shrimp so if you just want to get them taking manufactured foods, you can always try that and mix pellets on......should probably feed a variety of foods anyway, I use several different pellets, frozen foods, dried foods, and sometimes live crickets, waxworms, mealworms, earthworms etcIll try to get some better pics but i had them for about a month and i think thay about 4 inc how can i get them to eat pellets
