Hey! I own 3 bosc monitors and believe me you won't tame him untill hes at least a foot long! they are very defensive as babies but its all talk, just get in waste no time and pick him up and he'l soon tame down. I guess with the feeding you could tong feed him crickets etc? or try morios etc.
goodluck!
- The fridge idea sounds good also give that a try
