I haven't kept any trans pecos rat snakes so take this with a grain of salt lol, but as far as lighting goes I do know of a keeper who has quite a few subocs and keeps them with UVB and halogen lighting. They all seem to be doing well and she has made many observations of them basking. Additionally in the book The Complete Suboc by Dusty Rhoads, he mentions that although subocs are naturally nocturnal, in captive settings they do just fine with overhead lighting. Again, I have no personal experience but I thought this was information worth sharing![]()
