I have a peacock monitor, its care is essentially the same as the other tree monitors, atm I have it in a 5Lx2.5Wx6T ft enclosure. I'll try to get a few pics but my phone is almost dead lol

. You'll want the monitor to be able to move from one side of the cage to the other without being seen, reptilewhisperer on youtube has some amazing specimens so you should definitely check her out.
