What an adorable pic! You may want to try to make the light/dark more consistent for him if you can. It will be better for him. I completely understand the insomnia thing and the odd hours...don't get me wrong. Try to make his light and dark mimic the daylight hours outside though. When it is light outside, have his lights on...and when it is supposed to be dark...if you can't make it dark in your room for him...maybe put a towel over part of his enclosure to make it darker...as much as you can cover while still giving him air circulation. It helps them to regulate their cycles and be healthy and active when they should be and get rest when they should.
