Hi! First off I apologize that this post is long but I just need to get some answers before I go for a cornsnake. Anyways I've always loved snakes but never really had one before. I did have a Ball Python for a couple days at the start of the year but returned him due to personal problems and being stressed about care. That was at the beginning of the year and now I'm certain I have my personal problems sorted out and am willing to try owning a snake again. I have all the supplies from the last snake but cleaned and disinfected them all and have the tank setup again. I'm getting a cornsnake because everyone has said they are a better beginner snake than a Ball Python so I figured I'll get a cornsnake.I am familiar with the different needs between the two species but am not 100% sure so that's what this thread is for.

As for the tank it's a 20G long glass tank with locking mechanism. I have an UTH plugged into a thermostat and set to 85F. The cool end is 70-80F depending whether or not I have my fans on. I have two hides and silk vines for cover and aspen for substrate.

As for my really important questions I'm just wanting to know if the temperatures are correct?

Second question is humidity. I was always worried about the humidity in my BP's tank because it would not stay up no matter what. I'm not sure exactly what the humidity for a cornsnake should be even after reading caresheets. They say household humidity is fine. My current humidity is 20% when my window is open and 30% when it's closed. I live in Eastern Canada if that helps any. There is no water in the bowl currently but may raise it a little and nothing currently over the screen top. Basically is approx. 20-30% humidity alright for a cornsnake with misting during shedding without it getting sick or anything?

Third question is their personality you could call it I suppose? How squirmy and fast are the compared to a BP? I'm aiming to get a yearling depending on what I can get. And are they known for any hunger strikes like a BP? Sorry if it's hard to answer just trying to get a comparison to a BP.

Last question is escapes. Everyone always says they're escape masters which has me worried already. I have a metal screen lid that I set on top and it just sets in place and I rotate two locks at the front. I always give a tug at each corner and 3 are good but there is just a little gap in one that's making me nervous. I can't quite fit my pinkie in there if that helps although I could take a picture for reference if needed. I have 4 dogs and 2 cats. The snake would stay in my room but it couldn't get out or one of my other pets may find it. So I just want to prevent an escape as much as possible and an tips on doing that would be helpful.

Thank you for anyone who reads this as I just needed to ask these questions but didn't know who to ask. Once again I'm sorry for length.
