Ohhhhhhhhh dear.....sorry to break it to you, but your beardies' diets are horrible!!! Most petstores do have it very wrong all the time...
here are two great websites to help you with correct bearded dragon care.
www.reptilerooms.com
www.bearded-dragons.com/boards
I'll give you a short version...first...if your boys are housed together, seperate them immediately. Beardies are solitary creatures, and they are very territorial. They may seem fine and happy now, but they can be stressing each other out, and they can snap and turn on each other...if you need more explaination, those two sites explain it.
Now diet...veggies should be given everyday to a dragon over a year old here is a website for good and bad foods to feed:
http://www.beautifuldragons.503xtrem...Nutrition.html
protein should be given once a week. Crickets, goliath worms, silkworms, phoenix worms...mealworms are addictive, very poor in nutritional value, and somewhat dangerous (hard exoskeleton could cause impaction)
the dragon pellets can be used as a garnish on their greens, but alone they have as much nutritional value as cardboard.
Read through the websites, they are a great learning tool!!!
