*Digs out of the day gecko book*

I believe day geckos have roughly the same diet requirements. They also eat fruit, crickets etc. Day geckos can have a problem with the chitin of mealworms if given, though. Apparently the chitin can lead to impactions. Day geckos are more of a pollen and nectar eating gecko.

Gargoyle Geckos have basically the same diet requirements as cresties, but they eat more insects, according to the species complete guide book
