Next week I am going in vacation for a month. There is no one who can feed my Peacock Mantis while I am away can i just buy a cleanup crew and when he is humgry he will eat them? Will he eat too mutch and die?

it should be ok! thats what i would do!
just make sure he has enough hermits and snails and live shrimp if possible and maybe put your lighting on a timer so it still has proper daylight hours!
