mazuri feed has diets for all types of animals. i have fed my snappers on the croc diet large pellets. they also offer one for water turtles. both come in different size pellets and also a gel that can be mixed and stored in the freezer. the only problem i had with it is that i had to make more water changes. but to sum it up as for as pellet foods go, ally snappers remind me of dinosaurs " they want to hunt. they dont want to be fed" LOL
