I have 1 pair of central bluies and i keep them in much the same way as you would keep common bluies.I feed them on live insects and fruit & veg with calcium & vitamin suppliments.The size of the enclosure ikeep them in is 4ftx18'x18',i suply a basking light at one end of the cage and a uv emitting flouro is used to light the cage by day, i dont heat the cage at night.They are given fresh water every 3-4 days.
