branches up high, I managed to house a green basilisk and a red foot tortoise together for several months.
Both totally ignored eachother.
I fed the tortoise on the ground and the basilisk in a plastic dish in the branches. Both existed perfectly together.
Eventually the basilisk needed more room so I sold him to a friend with a larger set up who already had another basilisk.
just an idea to show you what can be possible, at least temporarily.
My red foot is still doing great now!
