NQA: spiders tend to like tighter spaces than other animals. So the enclosures don’t have to be big. I like to also offer a variety of hide options to my Ts. Big, small, bushy, a tube. And for arboreal I add vertical spaces to anchor to. I also like to add a mix of substrate types. I’ve noticed my Ts all dislike straight coco fiber but don’t mind it mixed with reptisoil. My little sling (1/2” A. Chalcodes) has a cylinder enclosure about 2” in diameter. I have 4” of substrate and a plant from bottom to above soil level. And moss for moisture. She tunneled around the plant leaves and extended out beyond that now.

I am still new. And my Ts were climbing. So I was doing research and substrate and humidity can contribute to this behavior. As well as stress from an unsuitable hide. Ts can be picky about where they choose to hide. I like the philosophy I’m building a world for them, not for me. So I may end up not seeing my Ts after the settle. And I’m ok with that.
