Hi everyone
I need help with my Flexarium (mesh viv). I have a Flexarium for my Cham and it's my first winter with him. I live up North (UK) and in the winter it can hit like -1 to -5 degrees sometimes and I'm worried about the effects of the night temperatures on my Cham. I keep him inside and the room isn't always that warm in the winter. Central heating sadly isn't an option. What could I do to ensure he is warm? Is there any extra heating I could supply for the flexarium to ensure he's warm? Or should I change his enclosure? Please help, no-one else seems to have been able to help
