I don't know much about the care of a texas wild snake, but I would let it go. It's unfair to take any animal out of the wild and then shove it into a little box. I'm sure you would take really good care of the animal but unless it is injured and you are trying to nurse it back to health, it really is unfair to the animal because you would never be able to provide the same amount of space that the animal used to have. It used to be able to roam the country side and now your going to restrict it to a tank. I know there are WC species out there and people do keep them, but I think most people try to avoid WC animals not because they are harder to keep but more because it's unfair to keep an animal that once lived in the Wild, now contained in a captive enviornment.
Just my 2 cents.
