where are you getting the night crawlers?...Someone tld me that the ones you buy as bait have stuff in them to plump them up which may be bad for the lizard...I have a Chinese Water Dragon and I fed him those...I stopped though...I drop my dragons crickets in his water bowl...they can't get out and it is fun watching him dive for em...BUT earthworms from a retile feeder supply would be goos...and they are high in nutrition...
