Don't leave live crickets in with the sling. Pre-kill it first, leave it in the enclosure and remove it if it's not eaten in 24 hours (mainly to prevent mould). The sling, if hungry, will go out and hunt but only if it's completely dark and calm (i.e. your picking up the enclosure likely means the T won't come out, hence leave it undisturbed for 24 hours).Hi All! I have a question regarding feeding and substrate. My Brazilian Black spiderling has burrowed under 2-3” of substrate and the feeder insects aren’t getting down to him. So he’s not eating. What am I doing wrong?
