I've been using freeze dried crickets. My beardie had no problems switching over to them. They are not all that cheap, but they are not messy, dont make a sound, and are very easy to feed, and are convienient (sp). They are made from flukers and are about 5-7 dollars. My dragon usually prefers the greens and I find about a dozen a day is about what he will eat without wasting. And they usually last about 2 weeks. I have only been able to find them at petco ($7-8.00 and on Foster and Smith (only $5.00 there) I tried the pellets and they gave my dragon very loose stools.(I've since stopped them, and Its still going on.) (He never had it before I started the pellets. They were the t-rex soft moist pellets for juvies. And advice on that would be great. Is it possibly a sign of good hydration??
