Well the tank that I have that I can use is 4ftx 1ft x 1.5ft I guess that would be too small for a bearded dragon. Is there a smaller lizard that I could keep a couple of together that would be OK in a tank that size? I already have a few marble geckoes (Christinus marmoratus) and would prefer a diurnal species that won't climb up the glass and escape. Oh and preferably in the same sort of price range
It's a difficult choice and in the end I picked the Beardie.
It's a great pet easy to care for and very friendly with kids.
Heat requirements are a bit of a challenge but in a enclosure like yours it shouldn't be a problem. 100W or 150W white bulb for light and heat. 10.0 UVB light (whether compact next to the white bulb or a tube on top of the enclosure) and eventually a heat pad for the night.
Feeding isn't complicated but required everyday: fresh veggies (carrots, broccoli, red capsicum, lettuce, zucchini), fresh fruit sometimes (apple, strawberries) and meat (crickets, woodies on a regular basis, mealworms as a treat)
I don't know if I read your post well, bu I wouldn't keep a beardie wih geckos, or you're going to end up with only a beardie!
I don't know much about blueys. They look great but I can't say which is better.
Good luck...
Cheers
