Yeah, you can feed crested geckos solely on Crested Gecko Diet if you don't want to deal with crickets.

The young ones tend to be more spazzy than the adults. But then I'd spaz too if some huge hand was coming after me.

My two new little ones, I just open the kritter keeper lid and they come out on their own.

I'm not sure if they like to be held, but they tolerate it well.
