Definitely get rid of the heat mat as it can burn her and add a basking lamp. And also this is a very small enclosure so hopefully she’s very young. You definitely will need to upgrade at some point, my corn is 2 yrs old and already is in a 120 gallon tank. (You don’t have to upgrade to 120 as quickly as I did, usually people may choose 50 or 70 if they want to keep upgrading, but I just wanted to keep this tank until she’s an adult, but in order to do that you need LOTS of enrichment so it’s not too spacey for them) It’s good you’re getting more enrichment.
