im glad you understand and i think its good what your doing, also, the snake is fine, i didnt use anything because i wanted to make sure she was okay before puting her in more stress of putting something weird over her face.
i am taking everything in that im being told, i read that this is suppost to be a very friendly site and ive been shown thats only half true. but im still here because i want the best for my snakes.
also about the under tank heater, im careful with it, i check on it several times daily and most of the time, over the substrate its barely even warm.
