That size tank should be fine for a pair of females but may also be ok for a boy and girl if the boy is not too big. I have been keeping and breeding netted dragons for years and actually prefer to keep them either individually or in a boy/girl pair to eliminate stress and dominance issues. Even girls can fight with each other and whilst they don’t normally dismember each other as boys do, one can often make the other ones life a complete misery and prevent her from getting near the heat and UV so watch out for that. Most netted dragons are fine to handle providing you choose the right time and environment to do it. Mine regularly curl up and go to sleep on me while I sit and watch TV in the lounge chair. I have 7 babies for sale at the moment and take the time to hand feed each of them individually to build human trust with them and even now most of them will jump onto my hand whenever I put it in the tank. Like most pets, it is very important to spend a lot of time with them while they are young if you want an exceptional pet for years to come. As far as breeding goes, they do all the work there and you really don’t have to incubate the eggs if you don’t have the time. One last recommendation would be to consider breeding your own food and this is something you can start right away. Woodies are prolific breeders and their babies grow to a perfect size for feeding young netteds within only a few weeks. The minute effort required and few dollars it takes to setup will save you a small fortune in the long run and lots of wasted time and fuel running backward and forwards to the pet shop.
