Have you tried f/t, ? Many a red blood are quiet, timid or easy feeders meaning they will just slither up and eat it if left in the enclosure..Many a blood keeper has experienced such and ours often feed this way..Adults and babies from the 09 season..So in essence many are not aggressive feeders but are good feeders, they just go about it in a gentle manner if you will..Of the 13 we hatched this year only one insisted on live and 12 ate f/t as stated above, just costs a buck or 2 to find out..
