I know that the slings might not be eating for a couple reasons.. one they might be near a molt or two they still haven't settled in enough to be ready for food.. but I put a small dubia roach in with each sling and neither has shown interest and as I feared the dubias burrowed under the substrate which is about an inch deep so now I have to remove the slings and dig out the dubia in each container and start over :/ but I remember reading on here that slings will eat pre killed prey so if I smash the roach head is it likely that a 1 to 1 ½ inch p regalis and p fasciata which is the same size will still eat it?
