you've only had him three days. imagine some aliens took you and put you in a big tank in their bedroom. you wanna eat? you wanna come out of your cave and let these monsters look at you? well this is essentially what the snake is going through. what is your setup? hot/cold side (temps), hides, substrate, etc. give him time. id let him sit there for a good 4-5 days and DO NOT HANDLE HIM. let him get used to his new tank and then he should eat.
