Cheers guys, especially Varanophile for laying out that info, very helpful, it covers a few things that were a bit murky for me. There's soooo much info out there on google - as a newbie it's hard to know what is right or wrong, and just where to begin. I think I'll also pick up the bearded dragon manual at some stage, just so I've got something that's not on line based to flick through.
Re. worms, what is the reason they are not so good to feed? Is it that they might tangle and cause impaction? (Just a guess)
Also, vet checks - how often do people find their beardie might need a vet trip? Do they need to go in for worming etc
