ball python has never shed

Mine is 2 and a half months old and he is in a 20 gallon from 3 weeks old! It took him 3 weeks to eat but never a problem since. You need to add decorations to the tank to fill up that empty space. It should be a little warmer, around 90. You shouldn't need to mist everyday! The humidity is probaly really high! I use coconut fibre and never need to spray the tank. My humidity is about 58%! You really need to invest into a digital thermometer/humidity to get accurate readings!
