my husband wanta a bearded dragon for his b-day which is in a week. Got a 20 long aquarium for a baby ( which we dont have yet )-our funds are kinda low at the moment and I need some advice on lighting mostly. The guy at the LPS said we needed a cacium based substrate for it but researching here I have learned thats not a good idea, right ? So using papertowels or newspaper is ok? What is the best, cheap lighting set up that we cud use--for now--to keep lil guy warm enuff? If we used regular house bulbs what should we get ? Where is the cheapest place to get the heat lamp itself ? Do we have to start off right away with uvb-uva lights or can it wait a couple of weeks ? What is repti-carpet ? what does it look like ? any other info that you can provide will be very welcomed !
