1. Do you have to feed beardies pinky mice?
No, you should not feed dragons pinky mice. some people offer them to females after laying eggs, but other than that, you shouldnt feed them pinkys as they are extremely high in raw fat.
2. Do they smell?
No, if you keep the cage clean, it wont smell. Your cickets might smell a little. Its tolerable.
3. What's this UVB light they need? I've got a light for reptiles, it's black and bell-shaped, and has a glow in the dark inside. It had a heat light in there before... is that OK?
Thats probably a black light, which you could use to keep your cage warm at night, without giving off too much light. You will need a UVB bulb as dragons require UVB to digest their food properly. They come in varying lenghts but look similar to a fish tank light. caution: there is a difference.
4. Are they happy alone?
Yes, although they look cute together as babies, its much safer to house them alone. Males will fight with other males. A male and a female will breed constantly (rough on female). 2 females will occasionally get along, but there are exceptions so its not worth the risk to try it.
5. Is there a difference between a male and female, personality-wise?
Not really, males may be slightly more aggressive, but not a big difference.
6. For my first dragon, would I be better off getting a baby or an adult?
Babies require a lot of attention and are a little more work. Adults dont seem to be as energetic and might not excite you. In my opinion, a good age for you first BD would be in the 6-8 month range.
Hope i helped! Good luck!
