Query: Not happening

I have 2 RES turtles, and neither of them will touch this food. I've tried giving it to them over a dozen times and using several strategies: mixing it in with their other food, letting it sit with them for 10 minutes before giving them anything else (when they're at their hungriest), even dusting it with their favorite vitamins. They sniff it and move on, no matter how hungry they are.
