Aphonopelma Chalcodes Setup

You did well to replace the screen for sure. It’s a little hard to get a feel for the dimensions from that angle but looks like more than enough space. The only thing that sticks out immediately is the vertical space. I would maybe add enough dirt so that if it opts to climb, a fall doesn’t result in a ruptured abdomen. The screen replacement goes part way to resolve that at least. You could add some plants even if just artificial. Not necessary by any means but could provide a greater feeling of safety to your T. I also wanted to ask what type of light fixture you have going on there.
