So I picked up a new beardie yesterday at the arlington convention. He is a Citrus Italian leatherback

so they were not specific on feeding, this morning I started giving him meal worms, I started with 5 then gave him one at a time and it got to like 20 so I stopped because I didnt know if they just eat and eat or they eat till they are full. I also am going to get him other protein this is just what I picked up from petco, today im going to a better pet store for a wider variety of food. And I know to give him some greens. Also, how often should he eat?? 3 times a day?

Ill post pictures of his size and his cage so i can get some feedback. The light I use is the powersun that is the all in one for uvb, uva, heat and light. And please dont hesitate on giving me any other information I should know!
