What other treats have you tried?
Flax, hemp, sunflower & pumpkin seeds all go down well, only in moderation though!
If he's enjoying his mix you could just hand feed some of that too.
Nuts are fine, I tend to give just tiny pieces more often rather than large pieces left in the cage except monkey nuts, I generally leave one of those in the cage for nibbling on along with a piece of biscrok dog biscuit.
Does he have any antos chews/whimzees? I'm sure he'd love those.
