Just a note on king/super mealworms...

I fed those to my leos once. They ate them quickly, however, 5 mins later I noticed that two of the geckos had regurgitated them.

I'm not sure of the cause, but I thought it was weird that two of them did the same thing.

I'm not sure on nightcrawlers, though...seems like they'd be a pretty large meal for a leo...
