Big crickets and new owner

Hello! i’m a first time beardie owner and my 5month old beardie is around 13 inches. i got him on may 12. he eats mostly celery leaves, mustard greens, strawberry, cucumber, carrots, grapes, and occasionally tomatoes. he eats crickets that are a little bit bigger than he should eat but all i have near my house is hardware stores that sell large crickets. the nearest pet smart is about 30 minutes away so i use the ones from hardware stores. i do break off the legs so they are easier to eat but he eats them just fine and poops 1-2 times a day. he has never had a problem with eating them. He is in a 25 gal tank and i plan on getter my a very big one around december. he is very happy and is kinda hyper when i handle him but he still is young. considering the crickets are big, i give hime 6-12 a day and he FOR SURE is not under fed. he is quite plump actaully. haha! anyway i want to make sure i’m doing everything right and being a good owner. ask any questions you have and any feedback too.

If he seems to be handling them ok then I think he's fine. I would probably order online as they are much cheaper and you can get the size you want. http://www.premiumcrickets.com/Products/1000-Crickets__1000.aspx
