I am planning on getting a corn snake here soon and was wondering what all I needed...I was told that since they are native to my area (southern indiana) I wouldn't have to use a heat source?...I have a 20 gallon tank ( not sure if long or breeder cuz I don't know how to tell)... how long can I kep a corn in that size tank...also information needed on humidity, temps, hides, and do they stress easy like ball pythons...I bought a bp that is my first snake...are corns needs the same as bps.thanks for any info.
