Oh yeah I totally forgot about that- most breeders I have read about and the one breeder I have talked to (mentioned above) feed exclusively commercial Crested Gecko diet, though they often start with gargoyle diet when the cresteds are young - my guess is that it has either higher protein or calcium. Judy is right commercial crestie diet is good- also Marla knows a TON on cresteds. In fact she has her own little community!
