First of all your temps are off. Cool side needs to be around 80. 71 is too cold. And hot side shouldn't be more than 90. Your heat sources need to be connected to thermostats to regulate the temps as they can get too hot and burn your snake.
As to the 3rd question your pics didn't show up. Try downloading the Tapatalk app.
