Once you find their favorite food stick to it.
Back in the days before pangea was around Rephashy was THE food however they mess around and changed their formula and many people complained that their gecko did not eat as much anymore.
Pangea is a GREAT food, I no longer feed the one with bugs since I actually offer Dubias once or twice a weeks but I feed the Banana Apricot right now (Chahoua loves it, Gargoyle not so much), based on sales (since I work a friend's table who sales geckos and food) the most popular in order are Watermelon, Apricot & Banana and Fruit Mix with bugs.
