The heat light that's in there now is a all in one is what they called it. The uvb fluorescent is what I was not sure about the strength of it being I bought it at walmart in the listing section and it said green house plants/reptile uvb pallast and bulb. Dose not give much more then that on the box. I like in a small town about a 1hr 15min from any type of pet store that caries anything for reptiles. So I ordered what I could and got what I could from Walmart and hardware store. As far as segregating them I can understand everyone point and have done alot of research on that topic before even getting beardies cuz I see alot of people on youtube with upwards of 5 per cage and my breeder with 2-3 per cage witch I felt was odd then read multiple articles that stated different that what I thought and what some of you guys are saying. That yes wild they are solo lizards but being domesticated they are brought into this world together and left together while being sold. Boosted and Phoenix have been with other dragons since they were born and if anything just hang out together. They bask in there own spots but at night cuddle together when they sleep. Phoenix being healthy dose get to the food faster but I do feed them separately so I can see how much they eat and to give them equal amounts. They arnt mean to each other but being lizards but if the day come were me or my wife see bully or aggression they will be separated, but right now I feel more of a friend ship or a family feeling with them.
