I am going to get my first corn snake at the next White Plains expo. I have a 20L tank with a sliding top and some accoutrements. I know it's not ready yet, I need an under tank heater and substrate, etc. my question is that there seems to be a gap between the tank and the sliding top and I wonder, after reading some of the stories here
, if you think a snake can escape and what I can do to make it more secure. Any advice, about security or care in general, would be welcomed!
