Bearded dragons will need there greens chopped up. The smaller the reptile the more finely chopped. A good mix of vegetables for these lizards are raw shredded carrots (not to much as it reduces the absorbtion of calcium), collard greens,water cress, beetroot leaf, dandelion greens, mustard greens, kale, and frozen vegetables like peas (shelled), and beans. You should avoid spinach and broccoli because too much can be harmful. Bearded dragons also like green leaf and romaine lettuce but these should be used sparingly due to the limited nutritional value. Vegetables should be fed to your animal daily. All these foods are easily attained in the produce section of your local grocery store.
Common insects available for reptiles are crickets, meal-worms, super-worms, and wax worms (wax worms should be treated as sweets to children). Bearded dragons will usually eat all types of insects. The insects should be gut loaded before feeding them to your pet lizard. Gut loading is just feeding them a nutritious meal before giving them to your bearded dragon. This way they pass along the nutrients to your lizard. There are many commercially available cricket and insect diets for gut loading. Insects should be a part of your bearded dragon’s diet every other day.
Phoenix Worms2:1 calcium to phosphorous ratio without the risk of a vitamin D-3 overdose.
ButterwormHave a natural fruity smell and a red to yellow colour that reptiles can't resist.
Also known as the Pachnodagrub, these beetle larvae are great for a treat, and offer an excellent, filling live-food alternative.
They are great as a treat, or a supplement.
Second only to Jumbo Silkworms in size, these really are meaty worms
super insects (roaches) - Low Chitin.
Roaches are a very under estimated food source as apart from being creepy and travel at super sonic speeds they full of protein, calcium, low phosphates and low chitin.They have good body-mass for gut-loading.
(Fast breeding easy to keep free food grow to approx 30mm) these have wings but cannot fly but can flutter. They can climb smooth surfaces so use Vaseline around the top of your container around 2-3" width so they cannot grip. Both male and female look the same apart from the female have slightly fatter abdomen.
(Not as fast breeding as the lobster roaches, grow to approx 60mm) Again these are a fantastic food source like the Lobster roaches but are a bit easier to keep as the breed at a slightly slower rate (depending how much heat source you let them have) they are not as fast as the lobster roaches so easier to catch. The males have wings but cannot fly while the females don't have wings as such and both are non climbers. Suggest use males as feeders and keep females for breeding and also balance the young out for feeding to your smaller reptiles.
Madagascan Hissing Roaches
(These have to be one of my favourite roaches, these are more like pets as they don't tend to travel at sonic speeds although they can get upto 2.2mph and are really quite friendly growing approx 50mm - 75mm and 25mm wide) Again easy to keep non flying non climbing roach low chitin huge body-mass for gut loading whilst I would refrain feeding a fully grown roach to my Beardies (maybe chopped in half) the young are easy to catch.The male have horns while the female tends to be a little bigger without horns.
Feeding the roaches
This is easy as eating an apple and chucking the core in for the roaches (will be gone in minutes) fruit = don't leave in the container over night as that creates the perfect environment for mites. apart from that some dry dog-food or dry cat-food biscuits and some water crystals in a small container.
Your pet Bearded Dragon will need a Calcium and vitamin D3 supplement. If your lizard is lacking D3 and calcium it can get metabolic bone disease which can be fatal. The supplement will come in a powder form which you can sprinkle on the vegetables or coat the insects. The easiest way to coat insects is to place them in a bag or cup and shake them around. You should add the supplement to your adult bearded dragon’s diet about once a week. Breeding females, babies, and juveniles will need them more often.
