Hi, take your time trying to get your new bp to eat before giving him time to acclimate to a new environment. Attempting to feed the day after receiving a new animal is just too soon. Try to get that uth regulated by a thermostat. The humidity issue can be resolved by purchasing a" glass versa top " for a 20 gallon tank. You then have to make appropriate holes in the plastic part of the top for air exchange. Oh, immediately switch substrates to 100% cypress mulch to improve that feeding response! Work on getting this guy on rats also. Stay in peace and not pieces. Good luck. A.C.
