I have 3 holdbacks and only one will eat for me. The "leonis phases wont eat!

I've tried:

Live pinkies
Brained
Cut in half longways (worked on the others that eat)
Yolk dipped half-pinks
anole tail sections

Any other suggestions, they are still in the incubation closet that stays at 81-84 should I move them into a cooler room?

Save these two from death and being fed to a zonata!
